GENERAL DESCRIPTION
The MX26LV004T/B 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 MX26LV004T/B is
packaged in 40-pin TSOP. It is designed to be repro-
grammed and erased in system or in standard EPROM
programmers.
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 2,000 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 MX26LV004T/B uses a 3.0V~3.6VVCC sup-
ply to perform the High Reliability Erase and auto Pro-
gram/Erase algorithms.
The standard MX26LV004T/B offers access time as fast
as 55ns, allowing operation of high-speed microproces-
sors without wait states. To eliminate bus contention,
the MX26LV004T/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
MX26LV004T/B uses a command register to manage
this functionality. The command register allows for 100%
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.
