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.
