DESCRIPTION
The M28010 devices consist of 128Kx8 bits of low
power, parallel EEPROM, fabricated with
STMicroelectronics鈥?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).
