DESCRIPTION

The M28010 devices consist of 128Kx8 bits of low

power,

parallel

EEPROM,

fabricated

with

STMicroelectronics’ proprietary double polysilicon

CMOS technology. The devices offer fast access

time, with low power dissipation, and require a

single voltage supply (5V, 3V or 2V, depending on

the option chosen).
