DESCRIPTION

This specification covers a range of 2K bit serial

EEPROM products, the ST93C56, 56C specified

at 5V ± 10% and the ST93C57C specified at 3V to

5.5V. In the text, products are referred to as

ST93C56.

The ST93C56 is a 2K bit Electrically Erasable

ProgrammableMemory(EEPROM)fabricatedwith

SGS-THOMSON’s High EnduranceSingle Polysili-

con CMOS technology. The memory is accessed

through a serial input (D) and output (Q). The 2K

bit memory is divided into either 256 x 8 bit bytes

or 128 x 16 bit words. The organization may be

selected by a signal applied on the ORG input.
