GENERAL DESCRIPTION
The MX29F200T/B is a 2-mega bit, single 5 Volt Flash
memory organized as 1M word x16 or 2M bytex8 MXIC's
Flash memories offer the most cost-effective and reli-
able read/write non-volatile random access memory.
The MX29F200T/B is packaged in 44-pin SOP and 48-
pin TSOP. It is designed to be reprogrammed and
erased in-system or in-standard EPROM programmers.
The standard MX29F200T/B offers access time as fast
as 55ns, allowing operation of high-speed microproces-
sors without wait states. To eliminate bus contention, the
MX29F200T/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
MX29F200T/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 programming operations produces reliable
cycling. The MX29F200T/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.
