DESCRIPTION

The M28LV16 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 2.7V to 3.6V power

supply. The circuit has been designed to offer a

flexible microcontroller interface featuring both

hardware and software handshaking with Data

Polling and Toggle Bit. The M28LV16 supports 64

byte page write operation. A Software Data Protec-

tion (SDP) is also possible using the standard

JEDEC algorithm.
