DESCRIPTION
The M24164 is a 16 Kbit EEPROM. The memory
is an electrically erasable programmable memory
(EEPROM) fabricated with STMicroelectronics’s
High Endurance Single Polysilicon CMOS technol-
ogy which guarantees an endurance typically well
above one million erase/write cycles with a data
retention of 40 years. The "-W" version operate with
a power supply value as low as 2.5V and the "-R"
version operate down to 1.8V.
Both Plastic Dual-in-Line and Plastic Small Outline
packages are available.
