General Description

The NM34W02 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).
