GENERAL DESCRIPTION
The MX29F004T/B is a 4-mega bit Flash memory
organized 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
MX29F004T/B is packaged in 32-pin PLCC, TSOP,
PDIP. It is designed to be reprogrammed and erased in
system or in standard EPROM programmers.
The standard MX29F004T/B offers access time as fast
as 70ns, allowing operation of high-speed
microprocessors without wait states. To eliminate bus
contention, the MX29F004T/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
MX29F004T/B 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
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 MX29F004T/B uses a 5.0V鹵10% 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 protection is proved for stresses up to
100 milliamps on address and data pin from -1V to
VCC + 1V.
