GENERAL DESCRIPTION
The MX29LV800T/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 MX29LV800T/B is packaged in 44-pin
SOP, 48-pin TSOP, and 48-ball CSP. It is designed to be
reprogrammed and erased in system or in standard
EPROM programmers.
The standard MX29LV800T/B offers access time as fast
as 70ns, allowing operation of high-speed microproces-
sors without wait states. To eliminate bus contention,
the MX29LV800T/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
MX29LV800T/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 MX29LV800T/B uses a 2.7V~3.6V 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.
