GENERAL DESCRIPTION
The MX29LV040 is a 4-mega bit Flash memory orga-
nized as 512K bytes of 8 bits. MXIC's Flash memories
offer the most cost-effective and reliable read/write non-
volatile random access memory. The MX29LV040 is
packaged in 32-pin PLCC and TSOP. It is designed to
be reprogrammed and erased in system or in standard
EPROM programmers.
The standard MX29LV040 offers access time as fast as
55ns, allowing operation of high-speed microprocessors
without wait states. To eliminate bus contention, the
MX29LV040 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
MX29LV040 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 MX29LV040 uses a 2.7V~3.6V 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 pro-
tection is proved for stresses up to 100 milliamps on
address and data pin from -1V to VCC + 1V.
