GENERAL DESCRIPTION  
The MX29LV081 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 MX29LV081 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 MX29LV081 uses a 2.7V~3.6V VCC supply  
to perform the High Reliability Erase and auto Program/  
Erase algorithms.  
The standard MX29LV081 offers access time as fast as  
70ns, allowing operation of high-speed microprocessors  
without wait states. To eliminate bus contention, the  
MX29LV081 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  
MX29LV081 uses a command register to manage this  
functionality. The command register allows for 100%  
TTL level control inputs and fixed power supply levels
