NM24C04U

The NM24C04U/05U devices are 4K (4,096) bit serial interface CMOS EEPROMs (Electrically Erasable Programmable Read- Only Memory). NM24C04U 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 of NM24C04U allows a minimal pin count packaging designed to simplify PC board layout requirements and offers the designer a variety of low voltage and low power options.

NM24C05U incorporates a hardware "Write Protect" feature, by which, the upper half of the memory of NM24C04U 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 VCC.

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