General Description
The FM34W02U is 2048 bits of CMOS non-volatile electrically erasable memory. This device is specifically designed to support Serial Presence Detect circuitry in memory modules. This communications protocol uses CLOCK (SCL) and DATA I/O (SDA) lines to synchronously clock data between the master (for example a microprocessor) and the slave EEPROM device(s).
