GENERAL DESCRIPTION
The MX29F022T/B is a 2-mega bit Flash memory
organized as 256K bytes of 8 bits only. MXIC's Flash
memories offer the most cost-effective and reliable read/
write non-volatile random access memory.The
MX29F022T/B is packaged in 32-pin PDIP, PLCC and
32-pin TSOP(I). It is designed to be reprogrammed and
erased in-system or in-standard EPROM programmers.
The standard MX29F022T/B offers access time as fast
as 55ns, allowing operation of high-speed microproc
essors without wait states. To eliminate bus contention,
the MX29F022T/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
MX29F022T/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
maximum EPROM compatibility.
MXIC's 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 combina-
tion of advanced tunnel oxide processing and low
internal electric fields for erase and programming
operations produces reliable cycling. The MX29F022T/
B uses a 5.0V
鹵
10% VCC supply to perform the High
Reliability Erase and 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.
