GENERAL DESCRIPTION
The MX28F2000P is a 2-mega bit Flash memory organized as 256K bytes of 8 bits each. MXIC's Flash
memories offer the most cost-effective and reliable
read/write non-volatile random access memory. The
MX28F2000P is packaged in 32-pin PDIP, PLCC
and TSOP. It is designed to be reprogrammed and
erased in-system or in-standard EPROM programmers.
The standard MX28F2000P offers access times as
fast as 70 ns, allowing operation of high-speed
microprocessors without wait states. To eliminate
bus contention, the MX28F2000P has separate chip
enable (CE) and output enable (OE ) controls.
MXIC's Flash memories augment EPROM functionality with in-circuit electrical erasure and
programming. The MX28F2000P uses a command
register to manage this functionality, while
maintaining a standard 32-pin pinout. The
command register allows for 100% TTL level control
inputs and fixed power supply levels during erase
and programming, while maintaining maximum
EPROM compatibility.
• Auto Erase (chip & block) and Auto Program
– DATA polling
– Toggle bit
• 10,000 minimum erase/program cycles
• Latch-up protected to 100mA from -1 to VCC+1V
• Advanced CMOS Flash memory technology
• Compatible with JEDEC-standard byte-wide 32-pin
EPROM pinouts
• Package type:
– 32-pin plastic DIP
– 32-pin PLCC
– 32-pin TSOP (Type 1)
MXIC Flash technology reliably stores memory contents even after 10,000 erase and program cycles.
The MXIC cell is designed to optimize the erase and
programming mechanisms. In addition, the combination of advanced tunnel oxide processing and low
internal electric fields for erase and programming
operations produces reliable cycling. The
MX28F2000P uses a 12.0V ± 5% VPP supply to
perform the Auto Program/Erase algorithms.
The highest degree of latch-up protection is
achieved with MXIC's proprietary non-epi process.
Latch-up protection is proved for stresses up to 100
milliamps on address and data pin from -1V to VCC
+ 1V.

MX28F2000P
AUTOMATIC PROGRAMMING
The MX28F2000P is byte programmable using the
Automatic Programming algorithm. The Automatic
Programming algorithm does not require the system to
time out or verify the data programmed. The typical
room temperature chip programming time of the
MX28F2000P is less than 5 seconds.
AUTOMATIC CHIP ERASE
The device may be erased using the Automatic Erase
algorithm. The Automatic Erase algorithm automatically programs the entire array prior to electrical erase.
The timing and verification of electrical erase are
controlled internal to the device.
AUTOMATIC BLOCK ERASE
The MX28F2000P is block(s) erasable using MXIC's
Auto Block Erase algorithm. Block erase modes allow
blocks of the array to be erased in one erase cycle.
The Automatic Block Erase algorithm automatically
programs the specified block(s) prior to electrical
erase. The timing and verification of electrical erase
are controlled internal to the device.
AUTOMATIC PROGRAMMING ALGORITHM
MXIC's Automatic Programming algorithm requires
the user to only write a program set-up command and
a program command (program data and address). The
device automatically times the programming pulse
width, provides the program verify, and counts the
number of sequences. A status bit similar to DATA
polling and a status bit toggling between consecutive
read cycles, provide feedback to the user as to the
status of the programming operation.
AUTOMATIC ERASE ALGORITHM
MXIC's Automatic Erase algorithm requires the user to
only write an erase set-up command and erase command. The device will automatically pre-program and
verify the entire array. Then the device automatically
times the erase pulse width, provides the erase verify,
and counts the number of sequences. A status bit
similar to DATA polling and a status bit toggling
between consecutive read cycles, provide feedback to
the user as to the status of the erase operation.
Commands are written to the command register using
standard microprocessor write timings. Register contents serve as inputs to an internal state-machine
which controls the erase and programming circuitry.
During write cycles, the command register internally
latches address and data needed for the programming
and erase operations. For system design simplification, the MX28F2000P is designed to support either
WE or CE controlled writes. During a system write
cycle, addresses are latched on the falling edge of WE
or CE whichever occurs last. Data is latched on the
rising edge of WE or CE whichever occur first. To
simplify the following discussion, the WE pin is used as
the write cycle control pin throughout the rest of this
text. All setup and hold times are with respect to the
WE signal.
MXIC's Flash technology combines years of EPROM
experience to produce the highest levels of quality, reliability, and cost effectiveness. The MX28F2000P electrically erases all bits simultaneously using Fowler-Nordheim tunneling. The bytes are programmed one byte at
a time using the EPROM programming mechanism of hot
electron injection.

MX28F2000P
COMMAND DEFINITIONS
When low voltage is applied to the VPP pin, the contents of the command register default to 00H, enabling
read-only operation.
Placing high voltage on the VPP pin enables read/write
operations. Device operations are selected by writing
specific data patterns into the command register. Table 1 defines these MX28F2000P register commands.
Table 2 defines the bus operations of MX28F2000P.

NOTES:
1. VPPL may be grounded, a no-connect with a resistor tied
to ground, or < VCC + 2.0V. VPPH is the programming
voltage specified for the device. When VPP = VPPL,
memory contents can be read but not written or erased.
2. Manufacturer and device codes may also be accessed
via a command register write sequence. Refer to Table
1. All other addresses don't care.
3. VID is the Silicon-ID-Read high voltage.(11.5V to 13v)
4. Read operations with VPP = VPPH may access array
data or Silicon ID codes.
5. With VPP at high voltage, the standby current equals ICC
+ IPP (standby).
6. Refer to Table 1 for valid Data-In during a write operation.
7. X can be VIL or VIH.

MX28F2000P
READ COMMAND
While VPP is high, for erasure and programming,
memory contents can also be accessed via the read
command. The read operation is initiated by writing
00H into the command register. Microprocessor read
cycles retrieve array data. The device remains enabled for reads until the command register contents
are altered.
The default contents of the register upon VPP powerup is 00H. This default value ensures that no spurious
alteration of memory contents occurs during the VPP
power transition. Where the VPP supply is hard-wired
to the MX28F2000P, the device powers up and
remains enabled for reads until the command register
contents are changed.
SILICON-ID-READ COMMAND
Flash-memories are intended for use in applications
where the local CPU alters memory contents. As such,
manufacturer- and device-codes must be accessible
while the device resides in the target system. PROM
programmers typically access signature codes by raising A9 to a high voltage. However, multiplexing high
voltage onto address lines is not a desired systemdesign practice.
contain an all-zero pattern, a self-timed chip erase and
verify begin. The erase and verify operations are
complete when the data on DQ7 is "1" at which time the
device returns to the Read mode. The system is not
required to provide any control or timing during these
operations.
When using the Automatic Chip Erase algorithm, note
that the erase automatically terminates when
adequate erase margin has been achieved for the
memory array(no erase verify command is required).
The margin voltages are internally generated in the
same manner as when the standard erase verify
command is used.
The Automatic set-up erase command is a commandonly operation that stages the device for automatic
electrical erasure of all bytes in the array. Automatic
set-up erase is performed by writing 30H to the
command register.
To command automatic chip erase, the command 30H
must be written again to the command register. The
automatic chip erase begins on the rising edge of the
WE and terminates when the data on DQ7 is "1" and
the data on DQ6 stops toggling for two consecutive
read cycles, at which time the device returns to the
Read mode.
The MX28F2000P contains a Silicon-ID-Read operation to supplement traditional PROM-programming
methodology. The operation is initiated by writing 90H
into the command register. Following the command
write, a read cycle from address 0000H retrieves the
manufacturer code of C2H. A read cycle from address
0001H returns the device code of 2AH.
SET-UP AUTOMATIC CHIP ERASE/ERASE
COMMANDS
The automatic chip erase does not require the device
to be entirely pre-programmed prior to excuting the
Automatic set-up erase command and Automatic chip
erase command. Upon executing the Automatic chip
erase command, the device automatically will program
and verify the entire memory for an all-zero data
pattern. When the device is automatically verified to
SET-UP AUTOMATIC BLOCK ERASE/ERASE
COMMANDS
The automatic block erase does not require the device
to be entirely pre-programmed prior to executing the
Automatic set-up block erase command and
Automatic block erase command. Upon executing the
Automatic block erase command, the device automatically will program and verify the block(s) memory for an
all-zero data pattern. The system is not required to
provide any controls or timing during these operations.
When the block(s) is automatically verified to contain
an all-zero pattern, a self-timed block erase and verify
begin. The erase and verify operations are complete
when the data on DQ7 is "1" and the data on DQ6 stops
toggling for two consecutive read cycles, at which time
the device returns to the Read mode. The system is
not required to provide any control or timing during
these operations.

MX28F2000P
When using the Automatic Block Erase algorithm, note
that the erase automatically terminates when adequate
erase margin has been achieved for the memory array
(no erase verify command is required). The margin
voltages are internally generated in the same manner
as when the standard erase verify command is used.
The Automatic set-up block erase command is a command only operation that stages the device for automatic electrical erasure of selected blocks in the array.
Automatic set-up block erase is performed by writing
20H to the command register.
To enter automatic block erase, the user must write
the command D0H to the command register. Block
addresses are loaded into internal register on the 2nd
falling edge of WE. Each successive block load cycles,
started by the falling edge of WE, must begin within
30us from the rising edge of the preceding WE.
Otherwise, the loading period ends and internal auto
block erase cycle starts. When the data on DQ7 is "1"
and the data on DQ6 stops toggling for two
consecutive read cycles, at which time auto erase
ends and the device returns to the Read mode.
Refer to page 2 for detailed block address.
SET-UP AUTOMATIC PROGRAM/PROGRAM
COMMANDS
RESET COMMAND
A reset command is provided as a means to safely
abort the erase- or program-command sequences.
Following either set-up command (erase or program)
with two consecutive writes of FFH will safely abort the
operation. Memory contents will not be altered. Should
program-fail or erase-fail happen, two consecutive
writes of FFH will reset the device to abort the
operation. A valid command must then be written to
place the device in the desired state.
WRITE OPERATON STATUS
TOGGLE BIT-DQ6
The MX28F2000P features a "Toggle Bit" as a method
to indicate to the host sytem that the Auto Program/
Erase algorithms are either in progress or completed.
While the Automatic Program or Erase algorithm is in
progress, successive attempts to read data from the
device will result in DQ6 toggling between one and
zero. Once the Automatic Program or Erase algorithm
is completed, DQ6 will stop toggling and valid data will
be read. The toggle bit is valid after the rising edge of
the second WE pulse of the two write pulse sequences.
The Automatic Set-up Program is a command-only
operation that stages the device for automatic programming. Automatic Set-up Program is performed by
writing 40H to the command register.
Once the Automatic Set-up Program operation is performed, the next WE pulse causes a transition to an
active programming operation. Addresses are
internally latched on the falling edge of the WE pulse.
Data is internally latched on the rising edge of the WE
pulse. The rising edge of WE also begins the
programming operation. The system is not required to
provide further controls or timings. The device will
automatically provide an adequate internally
generated program pulse and verify margin. The
automatic programming operation is completed when
the data read on DQ6 stops toggling for two
consecutive read cycles and the data on DQ7 and
DQ6 are equivalent to data written to these two bits, at
which time the device returns to the Read mode (no
program verify command is required).
P/N: PM0380
DATA POLLING-DQ7
The MX28F2000P also features Data Polling as a
method to indicate to the host system that the
Automatic Program or Erase algorithms are either in
progress or completed.
While the Automatic Programming algorithm is in operation, an attempt to read the device will produce the
complement data of the data last written to DQ7. Upon
completion of the Automatic Program algorithm an
attempt to read the device will produce the true data
last written to DQ7. The Data Polling feature is valid
after the rising edge of the second WE pulse of the two
write pulse sequences.
9
REV. 1.5, OCT 29, 1998
Page 10
While the Automatic Erase algorithm is in operation,
DQ7 will read "0" until the erase operation is completed. Upon completion of the erase operation, the
data on DQ7 will read "1". The Data Polling feature is
valid after the rising edge of the second WE pulse of
two write pulse sequences.
The Data Polling feature is active during Automatic
Program/Erase algorithms.
POWER-UP SEQUENCE
The MX28F2000P powers up in the Read only mode.
In addition, the memory contents may only be altered
after successful completion of a two-step command
sequence. Power up sequence is not required.
SYSTEM CONSIDERATIONS
MX28F2000P
During the switch between active and standby conditions, transient current peaks are produced on the
rising and falling edges of Chip Enable. The
magnitude of these transient current peaks is
dependent on the output capacitance loading of the
device. At a minimum, a 0.1uF ceramic capacitor (high
frequency, low inherent inductance) should be used
on each device between VCC and GND, and between
VPP and GND to minimize transient effects. In
addition, to overcome the voltage drop caused by the
inductive effects of the printed circuit board traces on
FLASH memory arrays, a 4.7uF bulk electrolytic
capacitor should be used between VCC and GND for
each eight devices. The location of the capacitor
should be close to where the power supply is connected to the array.

CE=VIL.
5. VIL min. = -0.6V for pulse width < 20ns.
6. If VIH is over the specified maximum value, programming
operation cannot be guranteed.
7. All currents are in RMS unless otherwise noted.(Sampled, not
100% tested.)
