NM24C02U

The NM24C02U/NM24C03U are 2K (2,048) bit serial interface CMOS EEPROMs (Electrically Erasable Programmable Read- Only Memory). NM24C02U fully conform to the Standard I2C™ 2-wire protocol which uses Clock (SCL) and Data I/O (SDA) pins to synchronously clock data between the "master" (for example a microprocessor) and the "slave" (the EEPROM device). In addition, the serial interface allows a minimal pin count packaging of NM24C02U designed to simplify PC board layout requirements and offers the designer a variety of low voltage and low power options.

NM24C03U incorporates a hardware "Write Protect" feature, by which, the upper half of the memory can be disabled against programming by connecting the WP pin to VCC. This section of memory then effectively becomes a ROM (Read-Only Memory) and can no longer be programmed as long as WP pin is connected to V_CC.

Fairchild EEPROMs are designed and tested for applications requiring high endurance, high reliability of NM24C02U  and low power consumption for a continuously reliable non-volatile solution for all markets.
