GENERAL DESCRIPTION
The MX29LV081B is a 8-mega bit Flash memory orga-
nized as 1M bytes of 8 bits. MXIC's Flash memories
offer the most cost-effective and reliable read/write non-
volatile random access memory. The MX29LV081B is
packaged in 40-pin TSOP. It is designed to be repro-
grammed and erased in system or in standard EPROM
programmers.
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 MX29LV081B uses a 2.7V~3.6VVCC supply
to perform the High Reliability Erase and auto Program/
Erase algorithms.
The standard MX29LV081B offers access time as fast
as 70ns, allowing operation of high-speed microproces-
sors without wait states. To eliminate bus contention,
the MX29LV081B has separate chip enable (CE) and
output enable (OE) controls.
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.
MXIC's Flash memories augment EPROM functionality
with in-circuit electrical erasure and programming. The
MX29LV081B uses a command register to manage this
functionality. The command register allows for 100%
TTL level control inputs and fixed power supply levels
