GENERAL DESCRIPTION

The Austin Semiconductor, Inc. AS58C1001 is a 1 Megabit CMOS

Electrically Erasable Programmable Read Only Memory (EEPROM)

organized as 131, 072 x 8 bits. The AS58C1001 is capable or in

system electrical Byte and Page reprogrammability.

The AS58C1001 achieves high speed access, low power consump-

tion, and a high level of reliability by employing advanced MNOS

memory technology and CMOS process and circuitry technology and

CMOS process and circuitry technology.

This device has a 128-Byte Page Programming function to make its

erase and write operations faster. The AS58C1001 features Data

Polling and a Ready/Busy signal to indicate completion of erase and

programming operations.

This EEPROM provides several levels of data protection. Hard-

ware data protection is provided with the RES pin, in addition to noise

protection on the WE signal and write inhibit during power on and off.

Software data protection is implemented using JEDEC Optional Stan-

dard algorithm.

The AS58C1001 is designed for high reliability in the most de-

manding applications. Data retention is specified for 10 years and

erase/write endurance is guaranteed to a minimum of 10,000 cycles in

the Page Mode.
