DESCRIPTION
This device is an electrically erasable programma-
ble memory (EEPROM) fabricated with
STMicroelectronics’s High Endurance, Advanced
Polysilicon, CMOS technology. This guarantees
an endurance typically well above one million
Erase/Write cycles, with a data retention of 10
years. The memory operates with a power supply
as low as 3 V.
The device is available in wafer form (either sawn
or unsawn) and in micromodule form (on film).
The memory is compatible with the I²C standard.
This is a two wire serial interface that uses a bi-di-
rectional data bus and serial clock. The memory
carries a built-in 7-bit unique Device Type Identifi-
er code (1010000) in accordance with the I²C bus
definition. Only one memory can be attached to
each I²C bus.
