DESCRIPTION
The M28C64 devices consist of 8192x8 bits of low
power, parallel EEPROM, fabricated with
STMicroelectronics’ proprietary single polysilicon
CMOS technology. The devices offer fast access
time, with low power dissipation, and require a
single voltage supply (5V or 3V, depending on the
option chosen).
The device has been designed to offer a flexible
microcontroller interface, featuring both hardware
and software handshaking, with Ready/Busy,
Data Polling and Toggle Bit. The device supports
a 64 byte Page Write operation. Software Data
Protection (SDP) is also supported, using the
standard JEDEC algorithm.
