NM24C04/05 – 4K-Bit Standard 2-Wire Bus Interface Serial EEPROM February 2000 NM24C04/05 – 4K-Bit Standard 2-Wire Bus Interface Serial EEPROM General Description The NM24C04/05 devices are 4096 bits of CMOS non-volatile electrically erasable memory. These devices conform to all specifications in the Standard IIC 2-wire protocol and are designed to minimize device pin count, and simplify PC board layout requirements. The upper half (upper 2Kbit) of the memory of the NM24C05 can be write protected by connecting the WP pin to VCC. This section of memory then becomes unalterable unless WP is switched to VSS. 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).
