1) The pick-up should always be left in its conductive bag until immediately prior to use.
2) The pick-up should never be subjected to external pressure or impact.
2. Repair notes
1) The pick-up incorporates a strong magnet, and so should never be brought close to magnetic materials.
2) The pick-up should always be handled correctly and carefully, taking care to avoid external pressure and
impact. If it is subjected to strong pressure or impact, the result may be an operational malfunction
and/or damage to the printed-circuit board.
3) Each and every pick-up is already individually adjusted to a high degree of precision, and for that reason
the adjustment point and installation
screws should absolutely never be touched.
4) Laser beams may damage the eyes!
Absolutely never permit laser beams to enter the eyes!
Also NEVER switch ON the power to the laser output part (lens, etc.) of the pick-up if it is damaged.
5) Cleaning the lens surface
If there is dust on the lens surface, the dust should be cleaned away by using an air bush (such as used
for camera lens). The lens is held by a delicate spring. When cleaning the lens surface, therefore, a cotton swab should be used, taking care not to distort this.
6) Never attempt to disassemble the pick-up.
Spring by excess pressure. If the lens is extremely dirty, apply isopropyl alcohol to the cotton swab. (Do
not use any other liquid cleaners, because they will damage the lens.) Take care not to use too much of
this alcohol on the swab, and do not allow the alcohol to get inside the pick-up.
Storage in conductive bag
NEVER look directly at the laser beam, and don’t let contact
fingers or other exposed skin.

NOTES REGARDING COMPACT DISC PLAYER REPAIRS
1. Preparations
1) Compact disc players incorporate a great many ICs as well as the pick-up (laser diode). These components are sensitive to, and easily affected by, static electricity. If such static electricity is high voltage,
components can be damaged, and for that reason components should be handled with care.
2) The pick-up is composed of many optical components and other high-precision components. Care must
be taken, therefore, to avoid repair or storage where the temperature of humidity is high, where strong
magnetism is present, or where there is excessive dust.
2. Notes for repair
1) Before replacing a component part, first disconnect the power supply lead wire from the unit
2) All equipment, measuring instruments and tools must be grounded.
3) The workbench should be covered with a conductive sheet and grounded.
When removing the laser pick-up from its conductive bag, do not place the pick-up on the bag. (This is
because there is the possibility of damage by static electricity.)
4) To prevent AC leakage, the metal part of the soldering iron should be grounded.
5) Workers should be grounded by an armband (1MΩ)
6) Care should be taken not to permit the laser pick-up to come in contact with clothing, in order to prevent
static electricity changes in the clothing to escape from the armband.
7) The laser beam from the pick-up should NEVER be directly facing the eyes or bare skin.

ESD PRECAUTIONS
Electrostatically Sensitive Devices (ESD)
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated circuits and some field-effect transistors and semiconductor chip components. The following techniques should
be used to help reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off
any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a
commercially available discharging wrist strap device, which should be removed for potential shock reasons
prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ESD devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static"
can generate electrical charges sufficient to damage ESD devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESD
devices.
6. Do not remove a replacement ESD device from its protective package until immediately before you are
ready to install it. (Most replacement ESD devices are packaged with leads electrically shorted together by
conductive foam, aluminum foil or comparable conductive materials).
7. Immediately before removing the protective material from the leads of a replacement ESD device, touch the
protective material to the chassis or circuit assembly into which the device will by installed.
CAUTION : BE SURE NO POWER IS APPLIED TO THE CHASSIS OR CIRCUIT, AND OBSERVE ALL
OTHER SAFETY PRECAUTIONS.
8. Minimize bodily motions when handing unpackaged replacement ESD devices. (Otherwise harmless motion
such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ESD device).

SETUP AND CONNECTIONS
• Ensure that the power switch of this unit (and of
other equipment to be connected) is set to “Off”
before commencing connection. We also strongly
recommend that you leave all system components
unplugged from AC power until after you have completed the interconnections described in this section.
• Do not block the ventilation holes of any of the
equipment and arrange them so that air can
circulate freely.
• Read through the instructions before connecting
other equipment.
• Ensure that you observe the color-coding when connecting audio and video cables.
VIDEO NOTES:
• While we suggest the use of component video for
higher quality pictures, you may also use the standard S-video or composite video connection if your
TV does not have component video inputs.The
component and S-video outputs are not available
simultaneously.
• The composite video output (yellow) combines the
complete video signal (composite) and sends it to
the TV (or to the A/V receiver) by one cable only.
Use this video output when your TV set is equipped
with a video input jack only.
• The S (separate) video output connector separates
the color (C) and luminance (Y) signals before transmitting them to the TV set in order to achieve a
sharper picture. Use the S-video cable when con-
necting the player to a TV equipped with an S-video
input for improved picture clarity.
• The component video outputs further separate the
color components of the video signal, optimizing the
DVD 27’s video performance. Component video
connections are preferred, when available on your
TV or receiver. If you are using a television or video
display that is compatible with high-resolution 480P
video signals, make sure to use the input jacks on
the video display marked “HD Component,” if available.Also, make sure to configure the display’s input
settings for use with “480P” video signals. You will
also need to change the scan type in the DVD 27’s
Video Setup menu from “Interlaced” to “Progressive.”
See page 20.
• Modern audio/video receivers are capable of connection to several video source devices, such as
the DVD 27 and a VCR, cable television set-top
box, HDTV tuner or other device. The receiver is
equipped with video monitor outputs for connection
to your television, projector or plasma display. As
you select any input source device, the receiver
selects the correct video input and routes it to the
correct video monitor output to your television. It is
recommended that you connect one of the video
outputs from the DVD 27 to the corresponding input
on your receiver to simplify operation of your home
entertainment system. Refer to the owner’s guide for
your receiver for more information.
• If your receiver is capable of multiroom operation, it
is recommended that you connect both the component and composite video outputs of the DVD 27 to
the receiver. This enables the highest-quality picture
(component video) for viewing in the main listening
room, while enabling the multiroom system, if it is
video-capable, to distribute the composite video signal to the remote zone. Consult the owner’s guide
for your receiver to determine whether it has video
multiroom capability.
Connecting to a TV Only
When using the DVD 27 with a television but no audio
receiver or processor, connect it as follows. Make the

SETUP AND CONNECTIONS
Connecting to a Receiver/Amplifier With a Dolby Digital or DTS Decoder
One of the major advantages of the DVD format is its
ability to use a variety of digital audio formats for the
ultimate in sonic performance. However, in order to
enjoy the benefits of digital audio, you must use a
receiver or processor that has digital audio decoding
capabilities and make an optical or coaxial digital audio
connection between the DVD 27 and your home theater system. This simple connection is made as shown
below with an optional coax or optical cable. Only one
of these connections is required, and both should not
be made at the same time.
NOTES FOR ANALOG AUDIO:
•If you wish to use the DVD 27 as the input for a
multiroom system, the
should be connected to the standard analog left/
right DVD or CD inputs on your digital receiver or
processor.
• The connection from the

using your DVD 27 alone, without turning on your
complete system, this connection must be made.

• When the audio signal is to be fed to an analog
receiver rather than to the TV, connect the

• The analog audio connection should also be made if
you wish to play high-resolution 96kHz PCM audio
discs where your receiver does not support 96kHz

TEST SCREEN
DVD is one of the highest quality sources ever made
available for in-home playback of prerecorded pictures
and sound. In order to make certain that your home
theater system is fully optimized to take advantage of
DVD’s superb picture quality, the DVD 27 offers a
built-in video test signal that makes it easy to calibrate
your TV or video display for proper playback.
Test Screen
With the test screen showing on your video display, the
following adjustments may be made:
• The proper color intensity setting on your TV.
• Proper color adjustments using the color bars, which
should be (left to right) black, white, yellow, cyan
(turquoise), green, magenta, red, blue, black.
• The proper color transition, seen as sharp
separation of the bars.
• The performance of the color circuits in your TV
(with “Video” signals); bar edges should show
no vertical crawling dots.
With the gray scale and the black/white fields below
the color bars, the brightness and contrast of your
screen can be adjusted.
NOTE: Most of the video adjustments using the
DVD 27’s test screen should be made using the
controls on your video display, with the DVD 27’s
controls set at their factory default position in the
center. If necessary, you may tweak the brightness
and sharpness using the controls found in the
DVD 27’s video adjustments menu.
Figure 9
TV Picture Adjustment With Test Screen
Brightness Adjustment:
1. Turn down the color control on your TV until the
color bars are visible in black and white.
2. Adjust the contrast on your TV to the lowest level
where you still can see all bars within the gray scale
in the test picture separately and clearly.
3. Adjust the brightness using the DVD 27 video
adjustments control so that the bars in the gray
scale are all visible.The bar furthest to the left has
to be as black as possible rather than gray, but the
next gradation must clearly be distinct from it.
All the bars in the gray scale should be gradually
and evenly changing from black to white, going
from left to right.
Contrast Adjustment:
1. Adjust the contrast on your TV until you see a bright
white bar in the lower right corner of the screen
and a deep-dark-black bar to the left. The optimal
contrast setting will depend on your preference and
the surrounding light in the TV room.
2. If the brightness of the white bar no longer increases
when the contrast is turned up or the borders of the
white “harman/kardon” letters on top bloom (overlight) into the black areas (drastically decreasing
the sharpness of the type), the contrast has been
turned up too much. Reduce the contrast until
these effects disappear and the video still looks
realistic.
3. If you are watching TV with customary surrounding
daylight, adjust the contrast so that a normal video
picture has about the same look as the surroundings in your room. That way the eye is relaxed
when watching the TV picture. This contrast setting
may be reduced when the surrounding light is
dimmed, thereby usually improving the sharpness
of a video significantly.
4. The gray scale in the middle line needs to have
the same clear difference between each bar as
before the contrast adjustment. If not, go back to
“
Brightness Adjustment” and repeat Step 3 and
then
“
Contrast Adjustment,” making only minor
adjustments each time for optimization.
Color Adjustment
1. When the brightness and contrast are set optimally,
turn up the color control to the level of your preference.Adjust to the level where the colors look
strong but still natural, not overdone. If the color
level is too high, depending on the TV, some of the
bars will seem wider or the color intensity will not
increase while the control is turned up. Then the
color control must be reduced again. Ultimately, you
also should test the color intensity with a video –
e.g., pictures of natural faces, flowers, fruit and vegetables, and other common natural articles for an
optimal setting of the color intensity.
2. Use the large white bar below the gray scale to
tweak the warmth of the picture. Every viewer has a
preference as to how the glow of the picture should
be. Some prefer a little colder picture, some a
warmer glow. The Tint function on your TV and the
white bar can be used to control this.Adjust the Tint
to the level where you feel the white color has the
tone you prefer.
Sharpness Adjustment
Contrary to intuition, the picture will appear sharper
and clearer with the sharpness, or Edges, setting
backed off from the maximum setting. Reduce the
sharpness setting on your television, and the Edges
setting on the DVD 27 video adjustments menu if necessary, to minimize the appearance of any white lines
between the bars in the gray scale portion of the test
screen.
Convergence and Edge Focus
The crosshatch pattern that surrounds the test screen
may be used to evaluate edge focus and convergence
in front- or rear-projection video displays. However, the
controls used to adjust these parameters are often not
user-accessible. In any event, these adjustments are
extremely complex, and require proper training and
experience to avoid worsening the situation. Therefore,
it is recommended that if you are unable to improve
the picture using the available controls, contact the
video display manufacturer’s authorized service representative for assistance.
When all desired setup and configuration entries have
been made, use the
⁄¤ Navigation Buttons n

Adjustments submenu. Press the

1 INTRODUCTION
The ST72F324L and ST72324BL devices are
members of the ST7 microcontroller family designed for the 3V operating range. They can be
grouped as follows:
– The 32-pin devices are designed for mid-range
applications
– The 44-pin devices target the same range of ap-
plications requiring more than 24 I/O ports.
All devices are based on a common industrystandard 8-bit core, featuring an enhanced instruc-

tion set and are available with FLASH or ROM program memory.
Under software control, all devices can be placed
in WAIT, SLOW, ACTIVE-HALT or HALT mode,
reducing power consumption when the application
is in idle or stand-by state.
The enhanced instruction set and addressing
modes of the ST7 offer both power and flexibility to
software developers, enabling the design of highly
efficient and compact application code. In addition
to standard 8-bit data management, all ST7 microcontrollers feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing
modes.

The M29W160E is a 16 Mbit (2Mb x8 or 1Mb x16)
non-volatile memory that can be read, erased and
reprogrammed. These operations can be performed using a single low voltage (2.7 to 3.6V)
supply. On power-up th e memory defaults to its
Read mode where it can be read in the same way
as a ROM or EPROM.
The memory is divided into blocks that can be
erased independently so it is possible to pres erve
valid data while old data is erased. Each block can
be protected independently to prevent accidental
Program or Erase commands from modifying the
memory. Program and Erase com m ands are wri tten to the Command Interface of t he memory. An
on-chip Program/Erase Controller simplifies the
process of programming or erasing the memory by
taking care of all of the special operations that are
required to update the memory contents.
The end of a program or erase operation can be
detected and any error conditions identified. The
command set required to control the memory is
consistent with JEDEC standards.
The blocks in the memory are asymmetrically arranged, see Figures 5 and 6, Block Addresses.
The first or last 64 KBytes have been divided into
four additional blocks. The 16 KByte Boot Block
can be used for small initialization code to start the
microprocessor, the two 8 KByte Parameter
Blocks can be used for parameter storage and the
remaining 32K is a small Main Block where the application may be stored.
Chip Enable, Output Enable and Write Enable signals control the bus operation of the memory.
They allow simple conne ction to most m icroprocessors, often without additional logic.
The memory is offered TSOP48 (12 x 20mm) and
TFBGA48 (0.8mm pitch) packages. The memory
is supplied with all the bits erased (set to ’1’).

DEVICE OPERATIONS
CLOCK (CLK)
The clock input is used as the reference for all SDRAM
operations. All operations are synchronized to the positive
going edge of the clock. The clock transitions must be
monotonic between V
high all inputs are assumed to be in valid state (low or high)
for the duration of setup and hold time around positive edge
of the clock for proper functionality and Icc specifications.
CLOCK ENABLE(CKE)
The clock enable (CKE) gates the clock onto SDRAM. If
CKE goes low synchronously with clock (set-up and hold
time same as other inputs), the internal clock suspended
from the next clock cycle and the state of output and burst
address is frozen as long as the CKE remains low. All other
inputs are ignored from the next clock cycle after CKE goes
low. When all banks are in the idle state and CKE goes low
synchronously with clock, the SDRAM enters the power
down mode from the next clock cycle. The SDRAM remains
in the power down mode ignoring the other inputs as long as
CKE remains low. The power down exit is synchronous as
the internal clock is suspended. When CKE goes high at
least “1CLK + tSS” before the high going edge of the clock,
then the SDRAM becomes active from the same clock edge
accepting all the input commands.
BANK ADDRESSES (A13~A12)
This SDRAM is organized as four independent banks of
1,048,576 words x 16 bits memory arrays. The A13~A12
inputs are latched at the time of assertion of
CAS to select the bank to be used for the operation. The
banks addressed A13~A12 are latched at bank active, read,
write, mode register set and precharge operations.
ADDRESS INPUTS (A0~A11)
The 20 address bits are required to decode the 1,048,576
word locations are multiplexed into 12 address input pins
(A0~A11). The 12 row addresses are latched along with
RAS and A13~A12 during bank active command. The 8 bit
column addresses are latched along with
A13~A12 during read or with command.

4.Issue 2 or more auto-refresh commands.
5.Issue a mode register set command to initialize the
mode register.
cf.) Sequence of 4 & 5 is regardless of the order.
The device is now ready for normal operation.
MODE REGISTER SET (MRS)
The mode register stores the data for controlling the
various operating modes of SDRAM. It programs the
CAS latency, burst type, burst length, test mode and
various vendor specific options to make SDRAM useful
for variety of different applications. The default value of
the mode register is not defined, therefore the mode
register must be written after power up to operate the
SDRAM. The mode register is written by asserting low
CS , RAS , CAS and WE (The SDRAM should
on
be in active mode with CKE already high prior to writing
the mode register). The state of address pins A0~A11
and A13~A12 in the same cycle as
WE going low is the data written in the mode
and
register. Two clock cycles is required to complete the
write in the mode register. The mode register contents
can be changed using the same command and clock
cycle requirements during operation as long as all banks
are in the idle state. The mode register is divided into
various fields into depending on functionality. The burst
length field uses A0~A2, burst type uses A3, CAS
latency (read latency from column address) use A4~A6,
vendor specific options or test mode use A7~A8,
A10/AP~A11 and A13~A12. The write burst length is
programmed using A9. A7~A8, A10/AP~A11 and
A13~A12 must be set to low for normal SDRAM
operation. Refer to the table for specific codes for
various burst length, burst type and CAS latencies.
CS , RAS , CAS
When
performs no operation (NOP). NOP does not initiate any new
operation, but is needed to complete operations which
require more than single clock cycle like bank activate, burst
read, auto refresh, etc. The device deselect is also a NOP
and is entered by asserting
the command decoder so that
the address inputs are ignored.

DEVICE OPERATIONS (Continued)
BANK ACTIVATE
The bank activate command is used to select a random row
in an idle bank. By asserting low on RAS and CS with
desired row and bank address, a row access is initiated. The
read or write operation can occur after a time delay of t
(min) from the time of bank activation. tRCD is the internal
timing parameter of SDRAM, therefore it is dependent on
operating clock frequency. The minimum number of clock
cycles required between bank activate and read or write
command should be calculated by dividing tRCD(min) with
cycle time of the clock and then rounding of the result to the
next higher integer. The SDRAM has four internal banks in
the same chip and shares part of the internal circuitry to
reduce chip area, therefore it restricts the activation of four
banks simultaneously. Also the noise generated during
sensing of each bank of SDRAM is high requiring some time
for power supplies to recover before another bank can be
sensed reliably. tRRD (min) specifies the minimum time required
between activating different bank. The number of clock
cycles required between different bank activation must be
calculated similar to t
required for the bank to be active to initiate sensing and
restoring the complete row of dynamic cells is determined by
RAS (min). Every SDRAM bank activate command must satisfy
t
t
RAS (min) specification before a precharge command to that
active bank can be asserted. The maximum time any bank
can be in the active state is determined by tRAS (max) and tRAS
(max) can be calculated similar to tRCD specification.
BURST READ
The burst read command is used to access burst of data on
consecutive clock cycles from an active row in an active
bank. The burst read command is issued by asserting low on
CS and RAS with WE being high on the positive edge
of the clock. The bank must be active for at least tRCD (min)
before the burst read command is issued. The first output
appears in CAS latency number of clock cycles after the
issue of burst read command. The burst length, burst
sequence and latency from the burst read command is
determined by the mode register which is already
programmed. The burst read can be initiated on any column
address of the active row. The address wraps around if the
initial address does not start from a boundary such that
number of outputs from each I/O are equal to the burst
length programmed in the mode register. The output goes
into high-impedance at the end of burst, unless a new burst
read was initiated to keep the data output gapless. The burst
read can be terminated by issuing another burst read or
burst write in the same bank or the other active bank or a
precharge command to the same bank. The burst stop
command is valid at every page burst length.
BURST WRITE
The burst write command is similar to burst read command
and is used to write data into the SDRAM on consecutive
clock cycles in adjacent addresses depending on burst
length
RCD specification. The minimum time
RCD
and burst sequence. By asserting low on
WE with valid column address, a write burst is
and
initiated. The data inputs are provided for the initial
address in the same clock cycle as the burst write
command. The input buffer is deselected at the end of
the burst length, even though the internal writing can be
completed yet. The writing can be complete by issuing a
burst read and DQM for blocking data inputs or burst
write in the same or another active bank. The burst stop
command is valid at every burst length. The write burst
can also be terminated by using DQM for blocking data
and procreating the bank t
be written into the active row. See DQM OPERATION
also.
DQM OPERATION
The DQM is used mask input and output operations. It
works similar to
writing during write operation. The read latency is two
cycles from DQM and zero cycle for write, which means
DQM masking occurs two cycles later in read cycle and
occurs in the same cycle during write cycle. DQM
operation is synchronous with the clock. The DQM
signal is important during burst interrupts of write with
read or precharge in the SDRAM. Due to asynchronous
nature of the internal write, the DQM operation is critical
to avoid unwanted or incomplete writes when the
complete burst write is required. Please refer to DQM
timing diagram also.
PRECHARGE
The precharge is performed on an active bank by
asserting low on clock cycles required between bank
activate and clock cycles required between bank
activate and
A13~A12 of the bank to be procharged. The precharge
command can be asserted anytime after t
satisfy from the bank active command in the desired
bank. t
cycles required to complete row precharge is calculated
by dividing tRP with clock cycle time and rounding up to
the next higher integer. Care should be taken to make
sure that burst write is completed or DQM is used to
inhibit writing before precharge command is asserted.
The maximum time any bank can be active is specified
RAS (max). Therefore, each bank activate command. At
by t
the end of precharge, the bank enters the idle state and
is ready to be activated again. Entry to power-down,
Auto refresh, Self refresh and Mode register set etc. is
possible only when all banks are in idle state.

DEVICE OPERATIONS (Continued)
AUTO PRECHARGE
The precharge operation can also be performed by using
auto precharge. The SDRAM internally generates the timing
to satisfy t
and CAS latency. The auto precharge command is issued at
the same time as burst write by asserting high on A10/AP,
the bank is precharge command is asserted. Once auto
precharge command is given, no new commands are
possible to that particular bank until the bank achieves idle
state.
BOTH BANKS PRECHARGE
Both banks can be precharged at the same time by using
Precharge all command. Asserting low on CS , RAS , and
WE with high on A10/AP after all banks have satisfied tRAS
(min) requirement, performs precharge on all banks. At the
end of t
state.
AUTO REFRESH
The storage cells of SDRAM need to be refreshed every
64ms to maintain data. An auto refresh cycle accomplishes
refresh of a single row of storage cells. The internal counter
increments automatically on every auto refresh cycle to
refresh all the rows. An auto refresh command is issued by
asserting low on
and
with both banks being in idle state and the device is not in
power down mode (CKE is high in the previous cycle). The
time required to complete the auto refresh operation is
specified by t
required can be calculated by driving t
time and them rounding up to the next higher integer. The
auto refresh command must be followed by NOP’s until the
auto refresh operation is completed. The auto refresh is the
preferred refresh mode when the SDRAM is being used for
normal data transactions. The auto refresh cycle can be
performed once in 15.6us or the burst of 4096 auto refresh
cycles in 64ms.

SELF REFRESH
The self refresh is another refresh mode available in the
SDRAM. The self refresh is the preferred refresh mode
for data retention and low power operation of SDRAM.
In self refresh mode, the SDRAM disables the internal
clock and all the input buffers except CKE. The refresh
addressing and timing is internally generated to reduce
power consumption. The self refresh mode is entered
from all banks idle state by asserting low on
RAS , CAS and CKE with high on WE . Once the self
refresh mode is entered, only CKE state being low
matters, all the other inputs including clock are ignored
to remain in the refresh.
The self refresh is exited by restarting the external clock
and then asserting high on CKE. This must be followed
by NOP’s for a minimum time of t
reaches idle state to begin normal operation. If the
system uses burst auto refresh during normal operation,
it is recommended to use burst 4096 auto refresh cycles
immediately after exiting self refresh.

SERIAL DATA (SDA): The SDA pin is bi-directional for serial data transfer. This pin is
open-drain driven and may be wire-ORed with any number of other open-drain or opencollector devices.
DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1 and A0 pins are device
address inputs that are hard wired for the AT24C01A and the AT24C02. As many as
eight 1K/2K devices may be addressed on a single bus system (device addressing is
discussed in detail under the Device Addressing section).
The AT24C04 uses the A2 and A1 inputs for hard wire addressing and a total of four 4K
devices may be addressed on a single bus system. The A0 pin is a no connect.

devices on a single bus to one. The A0, A1 and A2 pins are no connects.
WRITE PROTECT (WP): The AT24C01A/02/04/08A/16A has a Write Protect pin that
provides hardware data protection. The Write Protect pin allows normal read/write operations when connected to ground (GND). When the Write Protect pin is connected to

Device AddressingThe 1K, 2K, 4K, 8K and 16K EEPROM devices all require an 8-bit device address word
following a start condition to enable the chip for a read or write operation (see to Figure
7 on page 9).
The device address word consists of a mandatory “1”, “0” sequence for the first four
most significant bits as shown. This is common to all the Serial EEPROM devices.
The next 3 bits are the A2, A1 and A0 device address bits for the 1K/2K EEPROM.
These 3 bits must compare to their corresponding hardwired input pins.
The 4K EEPROM only uses the A2 and A1 device address bits with the third bit being a
memory page address bit. The two device address bits must compare to their corresponding hardwired input pins. The A0 pin is no connect.
The 8K EEPROM only uses the A2 device address bit with the next two bits being for
memory page addressing. The A2 bit must compare to its corresponding hardwired
input pin. The A1 and A0 pins are no connect.
The 16K does not use any device address bits but instead the three bits are used for
memory page addressing. These page addressing bits on the 4K, 8K and 16K devices
should be considered the most significant bits of the data word address which follows.
The A0, A1 and A2 pins are no connect.
The eighth bit of the device address is the read/write operation select bit. A read operation is initiated if this bit is high and a write operation is initiated if this bit is low.
Upon a compare of the device address, the EEPROM will output a “0”. If a compare is
not made, the chip will return to a standby state.
Write OperationsBYTE WRITE: A write operation requires an 8-bit data word address following the
device address word and acknowledgment. Upon receipt of this address, the EEPROM
will again respond with a “0” and then clock in the first 8-bit data word. Following receipt
of the 8-bit data word, the EEPROM will output a “0” and the addressing device, such as
a microcontroller, must terminate the write sequence with a stop condition. At this time
the EEPROM enters an internally timed write cycle, t
inputs are disabled during this write cycle and the EEPROM will not respond until the
write is complete (see Figure 8 on page 10).
PAG E WRITE: The 1K/2K EEPROM is capable of an 8-byte page write, and the 4K, 8K
and 16K devices are capable of 16-byte page writes.
A page write is initiated the same as a byte write, but the microcontroller does not send
a stop condition after the first data word is clocked in. Instead, after the EEPROM
acknowledges receipt of the first data word, the microcontroller can transmit up to seven
(1K/2K) or fifteen (4K, 8K, 16K) more data words. The EEPROM will respond with a “0”
after each data word received. The microcontroller must terminate the page write
sequence with a stop condition (see Figure 9 on page 10).
The data word address lower three (1K/2K) or four (4K, 8K, 16K) bits are internally
incremented following the receipt of each data word. The higher data word address bits
are not incremented, retaining the memory page row location. When the word address,
internally generated, reaches the page boundary, the following byte is placed at the
beginning of the same page. If more than eight (1K/2K) or sixteen (4K, 8K, 16K) data
words are transmitted to the EEPROM, the data word address will “roll over” and previous data will be overwritten.
, to the nonvolatile memory. All
WR
ACKNOWLEDGE POLLING: Once the internally timed write cycle has started and the
EEPROM inputs are disabled, acknowledge polling can be initiated. This involves send-

77
ing a start condition followed by the device address word. The read/write bit is
representative of the operation desired. Only if the internal write cycle has completed
will the EEPROM respond with a “0”, allowing the read or write sequence to continue.
Read OperationsRead operations are initiated the same way as write operations with the exception that
the read/write select bit in the device address word is set to “1”. There are three read
operations: current address read, random address read and sequential read.
CURRENT ADDRESS READ: The internal data word address counter maintains the
last address accessed during the last read or write operation, incremented by one. This
address stays valid between operations as long as the chip power is maintained. The
address “roll over” during read is from the last byte of the last memory page to the first
byte of the first page. The address “roll over” during write is from the last byte of the current page to the first byte of the same page.
Once the device address with the read/write select bit set to “1” is clocked in and
acknowledged by the EEPROM, the current address data word is serially clocked out.
The microcontroller does not respond with an input “0” but does generate a following
stop condition (see Figure 10 on page 10).
RANDOM READ: A random read requires a “dummy” byte write sequence to load in the
data word address. Once the device address word and data word address are clocked
in and acknowledged by the EEPROM, the microcontroller must generate another start
condition. The microcontroller now initiates a current address read by sending a device
address with the read/write select bit high. The EEPROM acknowledges the device
address and serially clocks out the data word. The microcontroller does not respond
with a “0” but does generate a following stop condition (see Figure 11 on page 11).
SEQUENTIAL READ: Sequential reads are initiated by either a current address read or
a random address read. After the microcontroller receives a data word, it responds with
an acknowledge. As long as the EEPROM receives an acknowledge, it will continue to
increment the data word address and serially clock out sequential data words. When the
memory address limit is reached, the data word address will “roll over” and the sequential read will continue. The sequential read operation is terminated when the
microcontroller does not respond with a “0” but does generate a following stop condition
(see Figure 12 on page 11).

Quality, low-cost, bipolar fabrication with innovative design concepts is employed for the TL3472 operational
amplifier. This device of fers 4 MHz of gain-bandwidth product, 13-V/µs slew rate, and fast settling time, without
the use of JFET device technology . Although the TL3472 can be operated from split supplies, it is particularly
suited for single-supply operation because the common-mode input voltage range includes ground potential
(V
). With a Darlington transistor input stage, this device exhibits high input resistance, low input offset
CC–
voltage, and high gain. The all-npn output stage, characterized by no dead-band crossover distortion and large
output voltage swing, provides high-capacitance drive capability, excellent phase and gain margins, low
open-loop high-frequency output impedance, and symmetrical source/sink ac frequency response. This
low-cost amplifier is an alternative to the MC33072 and the MC34072 operational amplifiers.
