GENERAL DESCRIPTION
The Austin Semiconductor, Inc. AS58LC1001 is a 1 Megabit CMOS
Electrically Erasable Programmable Read Only Memory (EEPROM)
organized as 131, 072 x 8 bits. The AS58LC1001 is capable or in
system electrical Byte and Page reprogrammability.
The AS58LC1001 achieves high speed access, low power
consumption, 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 AS58LC1001 features Data
Polling and a Ready/Busy signal to indicate completion of erase and
programming operations.
This EEPROM provides several levels of data protection.
Hardware 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 Standard algorithm.
The AS58LC1001 is designed for high reliability in the most
demanding 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.
