GENERAL DESCRIPTION
TheMX29F200CT/Bisa2-megabit, single5VoltFlash
memoryorganizedas1Mwordx16or2Mbytex8MXIC's
Flash memories offer the most cost-effective and reli-
able read/write non-volatile random access memory.
TheMX29F200CT/Bispackagedin44-pinSOPand48-
pin TSOP. It is designed to be reprogrammed and
erasedin-systemorin-standardEPROMprogrammers.
TTL level control inputs and fixed power supply levels
duringeraseandprogramming,whilemaintainingmaxi-
mum EPROM compatibility.
MXICFlashtechnologyreliablystoresmemorycontents
evenafter100,000eraseandprogramcycles. TheMXIC
cell is designed to optimize the erase and programming
mechanisms. In addition, the combination of advanced
tunneloxideprocessingandlowinternalelectricfieldsfor
erase and programming operations produces reliable
cycling. The MX29F200C T/B uses a 5.0V ±10% VCC
supply to perform the High Reliability Erase and auto
Program/Erasealgorithms.
ThestandardMX29F200CT/Boffersaccesstimeasfast
as70ns, allowingoperationofhigh-speedmicroproces-
sorswithoutwaitstates. Toeliminatebuscontention,the
MX29F200C T/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
MX29F200C T/B uses a command register to manage
thisfunctionality. Thecommandregisterallowsfor100%
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.
