NM24C04UFLZN Datasheet

4K-Bit Serial EEPROM 2-Wire Bus Interface


General Description
The NM24C04U/05U devices are 4K (4,096) bit serial interface CMOS EEPROMs (Electrically Erasable Programmable Read Only 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.

■The I2C™ interface allows the smallest I/O pincount of any EEPROM interface
■16 byte page write mode to minimize total write time per byte
■Typical 200µA active current (ICCA)
■Typical 1µA standby current (ISB) for "L" devices and 0.1µA standby current for "LZ" devices
■Endurance: Up to 1,000,000 data changes
■Data retention greater than 40 years

■I2C™ compatible interface
■4,096 bits organized as 512 x 8
■Extended 2.7V – 5.5V operating voltage
■100 KHz or 400 KHz operation
■Self timed programming cycle (6ms typical)
■"Programming complete" indicated by ACK polling
■NM24C05U: Memory "Upper Block" Write Protect pin
