• Low VCC write inhibit is equal to or less than 3.2V

• Package type:

- Sector Erase (16K-Byte x1, 8K-Byte x 2, 32K-Byte

x1, and 64K-Byte x 3)

• Auto Erase (chip & sector) and Auto Program

- Automatically erase any combination of sectors or

the whole chip with Erase Suspend capability.

- Automatically programs and verifies data at speci-

fied address

• 20 years data retention

GENERAL DESCRIPTION

The MX29F022T/B is a 2-mega bit Flash memory

organized as 256K bytes of 8 bits only. MXIC's Flash

memories offer the most cost-effective and reliable read/

write non-volatile random access memory. The

MX29F022T/B is packaged in 32-pin PDIP, PLCC and

32-pinTSOP(I). It is designed to be reprogrammed and

erased in-system or in-standard EPROM programmers.

MXIC's 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 combina-

tion of advanced tunnel oxide processing and low

internal electric fields for erase and programming

operations produces reliable cycling. The MX29F022T/

B uses a 5.0V ± 10% VCC supply to perform the High

Reliability Erase and auto Program/Erase algorithms.

The standard MX29F022T/B offers access time as fast

as 55ns, allowing operation of high-speed microproces-

sors without wait states. To eliminate bus contention,

the MX29F022T/B 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

MX29F022T/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.
