DESCRIPTION
Each device is an electrically erasable program-
mable memory (EEPROM) fabricated with STMi-
croelectronics’s
High
Polysilicon, CMOS technology. This guarantees
an endurance typically well above one million
Erase/Write cycles, with a data retention of
40 years. The memory operates with a power sup-
ply as low as 2.5 V.
The M14C32 is available in wafer form (either
sawn or unsawn) and in micromodule form (on
film). The M14C64 is available in micro-module
Endurance,
