DESCRIPTION
The M28C16 is a 2K x 8 low power Parallel
EEPROM fabricatedwith SGS-THOMSON proprie-
tary single polysilicon CMOS technology. The de-
vice offers fast access time with low power
dissipation and requires a 5V power supply. The
circuit has been designed to offer a flexible micro-
controller interface featuring both hardware and
software handshaking with Data Polling and Toggle
Bit. The M28C16 supports 64 byte page write op-
eration. A Software Data Protection (SDP) is also
possible using the standard JEDEC algorithm.
