GENERAL DESCRIPTION
during erase and programming, while maintaining maxi-
mum EPROM compatibility.
The MX29F080 is a 8-mega bit Flash memory organized
as 1024K bytes of 8 bits. MXIC's Flash memories offer
the most cost-effective and reliable read/write non-vola-
tile random access memory. The MX29F080 is pack-
aged in 40-pinTSOP or 44-pin SOP. It is designed to be
reprogrammed and erased in system or in standard
EPROM programmers.
MXIC Flash technology reliably stores memory
contents even after 10,000 erase and program
cycles. The MXIC cell is designed to optimize the
erase and program mechanisms. In addition, the
combination of advanced tunnel oxide processing
and low internal electric fields for erase and
programming operations produces reliable cycling.
The MX29F080 uses a 5.0V±10% VCC supply to
perform the High Reliability Erase and auto
Program/Erase algorithms.
The standard MX29F080 offers access time as fast as
70ns, allowing operation of high-speed microprocessors
without wait states. To eliminate bus contention, the
MX29F080 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
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
MX29F080 uses a command register to manage this
functionality. The command register allows for 100%
TTL level control inputs and fixed power supply levels
