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).

Features
■ PC100/PC133 Compliant
■ Extended Operating Voltage: 2.7V-5.5V
■ Software Write-Protection for first 128 bytes
■ Hardware Write-Protection for entire memory array
■ 200 µA active current typical
    – 1.0 µA standby current typical (L)
    – 0.1 µA standby current typical (LZ)
■ IIC compatible interface
    – Provides bidirectional data transfer protocol
■ Sixteen byte page write mode
    – Minimizes total write time per byte
■ Self timed write cycle
    - Typical write cycle time of 6ms
■ Endurance: 1,000,000 data changes
■ Data retention greater than 40 years
■ Packages available: 8-pin TSSOP and 8-pin SO
■ Temperature Ranges: Commercial and Extended
