The device powers on in the read mode. Command
sequences are used to place the device in other operation
modes such as program and erase. The device has the
capability to protect the data in any se ctor. Once the d ata
protection for a given sector is enabled, the data in that
sector cannot be changed usin g input levels between
ground and V

CC

.

The device is segmented into two memory planes. Reads
from memory plane B may be performed even while pro­gram or erase functions are being executed in memory
plane A and vice versa. This operation allows improved
system performance by no t requiri ng the syst em to wait for
a program or erase operation to complete before a read is
performed. To further increase the flexibility of the device, it

contains an Erase Suspend feature. This feature will put
the Erase on hold for any amount of time and let the user
read data from or program data to any of the remaining
sectors within the same memo ry plane. There is no rea son
to suspend the erase operation if the data to be read is in
the other memory plane. The end of a program or an Erase
cycle is det ect e d by th e Rea dy / Bu sy

pin, Data polling, or by

the toggle bit.
A V

PP

pin is provided to improve program/erase times at
lower supply vo ltages. Thi s pin does not ne ed to be uti­lized. If it is not used the pin should be connected to ground
or V

CC

. To take advantage of faster pr ogramming, the pi n
should supply 5.0 volts during program and erase opera­tions.

A six byte command (bypass unlock) sequence to remove
the requirement of entering the three byte prog ram
sequence is offered to further improve programming time.
After entering the six byte code, only si ngle pulses on the
write control lines are required for writing into the device.
This mode (single pulse byte/word program) is exited by
powering down the device, or by pulsing the RESET

pin

low and then bringing it back to V

CC

. Erase and Erase Sus­pend/Resume commands will not work while in this mode;
if entered they will result in data being programmed into the
device. It is not recommended that the six byte code reside

in the software of the final produ ct but only exist in external
programming code.

The BYTE

pin controls whethe r the device data I/O pins

operate in the byte or word configuration. If the BYTE

pin is
set at logic “1”, the device is in word configuration, I/O0­I/O15 are active and controlled by CE

and OE.

If the BYTE

pin is set at logic “0”, the devi ce is in byte con­figuration, and only data I/O pins I/O0-I/O7 are active and
controlled by CE

and OE. The data I/O pins I/O8-I/O14 are
tri-stated, and the I/O1 5 pin is us ed a s an inp ut for the LSB
(A-1) address function.

Block Diagram

Device Operation

READ:

The AT49BV16X4(T) is accessed like an EPROM.

When CE

and OE are low and WE is high, the data stored
at the memory location determined by the address pins are
asserted on the outputs. The outputs are put in the high
impedance state whenever CE

or OE is high. This dual-line
control gives designers flexibility in preventing bus conten­tion.

COMMAND SEQUENCES:

When the device is first pow­ered on it will be reset to the read or standby mode
depending upon the state of the control line inputs. In order
to perform other device functions, a series of command

sequences are entered into the device. The command
sequences are shown in the Com mand Definition s table
(I/O8 - I/O15 are don't care inputs for the command codes).
The command sequences are written by applying a low
pulse on the WE

or CE input with CE or WE low (respec-

tively) and OE

high. The address is latched on the falling

edge of CE

or WE, whichever occurs last. The data is

latched by the first rising edge of CE

or WE. Standard
microprocessor write timings are used. The address loca­tions used in the command sequences are not affected by
entering the command sequences.

RESET:

A RESET

input pin is p rov ided to e ase some sy s-

tem application s. When RE SET

is at a logic high level, the
device is in its standa rd oper at ing mod e. A low l evel on th e
RESET

input halts the prese nt device oper ation and puts
the outputs of the de vice in a hi gh impedan ce stat e. When
a high level is reasse rted on the RES ET

pin, the device
returns to the Read or Standby mod e, depending upon the
state of the control inputs. By applying a 12V ± 0.5V input
signal to the RESET

pin any sector can be reprogrammed
even if the sector lockout feature has been enabled (see
Sector Programming Lockout Override section).

ERASURE:

Before a byte/word ca n be reprogramm ed, it
must be erased. The erased state of memory bits is a logi­cal “1”. The entire device can be erased by using the Chip
Erase command or individual sectors can be erased by
using the Sector Erase commands.

CHIP ERASE:

The entire device can be erased at one
time by using the 6-byte chip erase software code. After the
chip erase has been in itiate d, the devi ce wil l internal ly tim e
the erase operation so that no external clocks are required.
The maximum time to erase the chip is t

EC

.

If the sector lockout has been enabled, the Chip Erase will
not erase the data in the secto r th at ha s be en l oc ked; it wi ll
erase only the unprotected sectors. After the chip erase,
the device will return to the read or standby mode.

SECTOR ERASE:

As an alternative to a full chip erase, the
device is organized into forty sectors (SA0 - SA39) that can
be individually erased . The Secto r Erase comm and is a six
bus cycle operation. The sector ad dress is latched on the
falling WE

edge of the sixth cy cle whil e the 30H d ata inpu t

command is latched on the rising edge of WE

. The sector

erase starts after the rising edge of WE

of the sixth cycle.
The erase operation is i nterna ll y con troll ed ; it wi ll aut oma ti­cally time to completion. The maximum time to erase a sec­tion is t

SEC

. When the sector programming lockout feature
is not enabled, the sector will erase (from the same sector
erase command). Once a sector has been protected, data
in the protected s ectors cannot be changed unles s the
RESET pin is taken to 12V ± 0. 5V. An attempt to erase a
sector that has been pr otected wi ll result in the operation
terminating in 2 µs.

BYTE/WORD PROGRAMMING:

Once a memory block is
erased, it is programmed (to a logical “0”) on a byte-by-byte
or on a word-by- word ba si s. Pr o gr amm ing i s ac co mpl is he d
via the intern al device command r egister and is a 4-b us
cycle operation. The devic e will automati cally gener ate the
required internal program pulses.

Any commands written to the c hip during the em bedded
programming cycle will be ignored. If a hardware reset hap­pens during programming, the data at the location being
programmed will be corrupted. Please note that a data “0”
cannot be programmed back to a “1”; only erase operations
can convert “0”s to “1”s. Programming is completed after

the specified t

BP

cycle time. The DATA polling feature or
the toggle bit feature may be used to indicate the end of a
program cycle.

SECTOR PROGRAMMING LOCKOUT:

Each sector has a
programming lockout featur e. This feature prevents pro­gramming of data in the design ated sectors o nce the fea­ture has been enabled. These sectors can contain secure
code that is used to bring up the system. Enabling the lock­out feature will all ow the boot code to stay i n the device
while data in the rest of the device is upd ated. Thi s featur e
does not have to be activated; any sector’s usage as a
write protected region is optional to the user.

Once the feature is enabled, the data in the protected sec­tors can no longer be erased or programmed when input
levels of 5.5V or less are used. Data in the remaining sec­tors can still be changed through the regular programming
method. To activate the lo ck ou t fea tur e, a seri es of s ix pr o­gram commands to specific addresses with specific data
must be performed. Please refer to the Command Defini­tions table.

SECTOR PROGRAMMING LOCKOUT OVERRIDE:

The
user can override the sector programming lockout by taking
the RESET

pin to 12V ± 0.5V. By doing this prote cted da ta
can be altered through a chip erase, sector era se or
byte/word program ming. When the RESET

pin is brought
back to TTL levels th e secto r programm ing lock out featu re
is again active.

ERASE SUSPEND/ERASE RESUME:

The erase suspen d
command allows the system to interrupt a sector erase
operation and then program or read data from a different
sector within the same plane. Since this device has a dual
plane architecture, there is no need to use the erase sus­pend feature while erasin g a sec tor when y ou want to r ead
data from a sector in the other plane. After the erase sus­pend command is given, the device requires a maximum
time of 15 µs to suspend the erase operation. After the
erase operation has been suspended, the plane which con­tains the suspended sec tor enters th e erase-s uspend-r ead
mode. The system can then read data or program da ta to
any other sector within the device. An address is not
required during the erase suspend comm and. During a
sector erase suspend, another sector cannot be erased. To
resume the sector erase operation, the system must write
the erase resume command. The erase resume command
is a one bus cycl e co mma nd, whi c h d oes req ui re the p lan e
address (determined by A18 and A19). The device also
supports an erase suspend during a complete chip erase.
While the chip erase is suspen ded, the use r can read from
any sector within the me mory that is protec ted. The com­mand sequence for a ch ip erase suspen d and a sector
erase suspend are the same.

PRODUCT IDENTIFICATION:

The product identification

mode identifies the device and manufacturer as Atmel. It

AT49BV16X4(T)

5

may be accessed by hardware or software operation. The
hardware operation mode can be used by an external pro­grammer to identify the correct programming algorithm for
the Atmel product.

For details, see O peratin g Modes (for har dware operatio n)
or Software Product Identification. The manufacturer and
device code is the same for both modes.

DATA POLLING:

The AT49BV16X4(T) features DATA
polling to indicate the end of a program cycle. During a pro­gram cycle an attempted read of the last byte/word loaded
will result in the complement of the loaded data on I/O7.
Once the program cycle has been completed, true data is
valid on all outputs and th e next cyc le may be gin. Du ring a
chip or sector erase operation, an attempt to read the
device will give a “0” on I/O7. Once the program or erase
cycle has completed, true data will be read from the device.
DATA

polling may begi n at any ti me during the program

cycle. Please see “Status Bit Table” for more details.

TOGGLE BIT:

In addition to DATA

polling the
AT49BV16X4(T) provides another method for determining
the end of a program or erase cycle. Du ring a program or
erase operation, successive attempts to read data from the
same memory plane will result in I/O6 toggling between
one and zero. Once the program cycle has completed, I/O6
will stop toggling and valid data will be read. Examining the
toggle bit may begin at any time during a program cycle.

An additional to ggle bit is available on I/O2 whi ch can be
used in conjunction with the toggle bit which is available on
I/O6. While a sector is erase suspe nded, a read or a pro­gram operation fr om th e su sp ended sector will re sul t in th e

I/O2 bit togglin g. Please see s tatus bit table fo r more
details.

RDY/BUSY

:

An open drain READY/BUSY

output pin pro­vides another method of detecting the end of a progr am or
erase operation. RDY/BUSY

is actively pulled low during
the internal program and erase cycles and is released at
the completion of the cycle. The open drain connection
allows for OR-tying of several devices to the same
RDY/BUSY

line.

HARDWARE DATA PROTECTION:

Hardware features
protect against inadvertent programs to the
AT49BV16X4(T) in the following ways: (a) V

CC

sense: if

V

CC

is below 1.8V (typical), the program function is inhib-

ited. (b) V

CC

power on delay: once VCC has reached the

V

CC

sense level, the device will automatically time out 10
ms (typical) before prog ramming. (c) Program inhibi t: hold­ing any one of OE

low, CE high or WE high inhib its pro­gram cycles. (d) Noise filter: pulses of less than 15 ns
(typical) on the WE

or CE inputs will not initiate a program

cycle.

INPUT LEVELS:

While operating with a 2.7V to 3.6V

power supply, the ad dress inpu ts and cont rol inputs (OE

,

CE

, and WE) may be dr iven from 0 to 5.5V without
adversely affecting the operation of the device. The I/O
lines can only be driven from 0 to V

CC

+ 0.6V.

OUTPUT LEVELS:

Output High Levels (V

OH

) are equal to

V

CCQ

- 0.2V (n ot VCC). For 2.7V - 3.6V output levels, V

CCQ

must be tied to VCC. For 1.8V - 2.2V output leve ls, V

CCQ

must be regulated to 2.0V ± 10% while VCC must be regu­lated to 2.7V - 3.0V (for minimum power).

Notes: 1. The DATA FORMAT in each bus cycle is as follows: I/O15 - I/O8 (Don’t Care); I/O7 - I/O0 (Hex).

The ADDRESS FORMAT in each bus cycle is as follows: A15 - A0 (Hex), A-1, A14 - A19 (Don’t Care).

2. Either one of the Product ID Exit commands can be used.

3. SA = sector address. Any byte/word address within a sector can be used to designate the sector address (see next four
pages for details).

4. When the sector programming lockout feature is not enabled, the sector will erase (from the same sector erase command).
Once the sector has been protected, data in the protected sectors cannot be changed unless the RESET

pin is taken to

12V ± 0.5V.

5. PA is the plane address (A19 - A18).
