GENERAL DESCRIPTION
The MX29F400C T/B is a 4-mega bit Flash memory or-
ganized as 512K bytes of 8 bits or 256K words of 16 bits.
MXIC's Flash memories offer the most cost-effective and
reliable read/write non-volatile random access memory.
The MX29F400C T/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 MX29F400C T/B offers access time as
fast as 55ns, allowing operation of high-speed micropro-
cessors without wait states. To eliminate bus conten-
tion, the MX29F400C T/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
MX29F400C T/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 MX29F400C T/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.
