www.DataSheet4U.com NM24C16U/NM24C17U – 16K-Bit Serial EEPROM 2-Wire Bus Interface August 1999 NM24C16U/NM24C17U 16K-Bit Serial EEPROM 2-Wire Bus Interface General Description The NM24C16U/17U devices are 16K (16,384) bit serial interface CMOS EEPROMs (Electrically Erasable Programmable ReadOnly Memory). These devices 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 designed to simplify PC board layout requirements and offers the designer a variety of low voltage and low power options. NM24C17U 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 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.
