- Provides a hardware method of detecting program
or erase operation completion.
• Sector protection
- Sector protect/chip unprotect for 5V/12V system.
- Hardware method to disable any combination of
sectors from program or erase operations
- Tempory sector unprotect allows code changes in
previously locked sectors.

• Compatibility with JEDEC standard
- Pinout and software compatible with single-power
supply Flash
GENERAL DESCRIPTION
The MX29F800T/B is a 8-mega bit Flash memory or-
ganized as 1M bytes of 8 bits or 512K words of 16 bits.
MXIC's Flash memories offer the most cost-effective and
reliable read/write non-volatile random access memory.
The MX29F800T/B is packaged in 44-pin SOP, 48-pin
TSOP. It is designed to be reprogrammed and erased
in system or in standard EPROM programmers.
The standard MX29F800T/B offers access time as fast
as 70ns, allowing operation of high-speed microproces-
sors without wait states. To eliminate bus contention,
the MX29F800T/B 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
MX29F800T/B uses a command register to manage this
functionality. The command register allows for 100%
TTL level control inputs and fixed power supply levels
during erase and programming, while maintaining maxi-
mum EPROM compatibility.
MXIC Flash technology reliably stores memory contents
even after 100,000 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 program operations produces reliable cy-
cling. The MX29F800T/B uses a 5.0V±10% VCC sup-
ply to perform the High Reliability Erase and auto Pro-
gram/Erase algorithms.
The highest degree of latch-up protection is achieved
with MXIC's proprietary non-epi process. Latch-up pro-
tection is proved for stresses up to 100 milliamps on
address and data pin from -1V to VCC + 1V.

COMMAND DEFINITIONS
Device operations are selected by writing specific ad-
dress and data sequences into the command register.
Writing incorrect address and data values or writing them
in the improper sequence will reset the device to the
read mode. Table 1 defines the valid register command
sequences. Note that the Erase Suspend (B0H) and
Erase Resume (30H) commands are valid only while
the Sector Erase operation is in progress. Either of the
two reset command sequences will reset the
device(when applicable).
