GENERAL DESCRIPTION
TheMX29F8100isa8-megabitFlashmemoryorganized
as either 512K wordx16 or 1M bytex8. The MX29F8100
includes 8-128KB(131,072) blocks or 8-64KW(65,536)
blocks. MXIC's Flash memories offer the most cost-
effective and reliable read/write non-volatile random
access memory. The MX29F8100 is packaged in 48-pin
TSOP or 44-pin SOP. For 48-pin TSOP, CE2 and RY/BY
are extra pins compared with 44-pin SOP package. This
istooptimizetheproducts(suchassolid-statediskdrives
or flash memory cards) control pin budget. PWD is
available in 48 -pin TSOP for low power environment. All
the above three pins(CE2,RY/BY and PWD) plus one
extra VCC pin are not provided in 44-pin SOP. It is
designed to be reprogrammed and erased in-system or
in-standard EPROM programmers.
To allow for simple in-system reprogrammability, the
MX29F8100 does not require high input voltages for
programming. Five-volt-only commands determine the
operation of the device. Reading data out of the device
is similar to reading from an EPROM.
MXIC Flash technology reliably stores memory contents
even after 10,000 cycles. The MXIC's 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
programming operations produces reliable cycling. The
MX29F8100 uses a 5V ±10% VCC supply to perform the
Auto Erase and Auto Program 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.
The standard MX29F8100 offers access times as fast as
100ns,allowingoperationofhigh-speedmicroprocessors
without wait. To eliminate bus contention, the
MX29F8100 has separate chip enables(CE1 and CE2),
output enable (OE), and write enable (WE) controls.
MXIC's Flash memories augment EPROM functionality
with in-circuit electrical erasure and programming. The
MX29F8100 uses a command register to manage this
functionality. Thecommandregisterallowsfor100%TTL
level control inputs and fixed power supply levels during
erase and programming, while maintaining maximum
EPROM compatibility.
