General Description,
The NM24C08U/09U devices are 8K (8,192) 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.
Features
■ 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
Functions
■ I2C™ compatible interface
■ 8,192 bits organized as 1,024 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
■ NM24C09U: Memory "Upper Block" Write Protect pin
