GENERAL DESCRIPTION
The MX28F2000T is a 2-mega bit Flash memory or-
ganized as 256K bytes of 8 bits each. MXIC's Flash
memories offer the most cost-effective and reliable
read/write non-volatile random access memory. The
MX28F2000T is packaged in 32-pin PDIP and PLCC
. It is designed to be reprogrammed and erased in-
system or in-standard EPROM programmers.
The standard MX28F2000T offers access times as
fast as 90 ns, allowing operation of high-speed
microprocessors without wait states. To eliminate
bus contention, the MX28F2000T has separate chip
enable (CE) and output enable (OE) controls.
MXIC's Flash memories augment EPROM function-
ality with in-circuit electrical erasure and
programming. The MX28F2000T uses a command
register to manage this functionality, while
maintaining a standard 32-pin pinout. 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 con-
tents even after 10,000 erase and program cycles.
The MXIC cell is designed to optimize the erase and
programming mechanisms. In addition, the combi-
nation of advanced tunnel oxide processing and low
internal electric fields for erase and programming
operations produces reliable cycling. The
MX28F2000T uses a 12.0V ± 5% VPP supply to
perform the 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.
