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.
