GENERAL DESCRIPTION
The MX29LV800BT/BB is a 8-mega bit Flash memory
organized 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 MX29LV800BT/BB 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.
100% TTL level control inputs and fixed power supply
levels during erase and programming, while maintaining
maximum 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 cycling. The MX29LV800BT/BB uses a 2.7V~3.6V VCC
supply to perform the High Reliability Erase and auto
Program/Erase algorithms.
The standard MX29LV800BT/BB offers access time as
fast as 70ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29LV800BT/BB 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 protection is proved for stresses up to 100 milliamperes 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
MX29LV800BT/BB uses a command register to manage this functionality. The command register allows for
