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 I2Câ„¢ 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
â–  The I2Câ„¢ interface allows the smallest I/O pincount of any EEPROM interface
â–  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
â–  Endurance: Up to 1,000,000 data changes
â–  Data retention greater than 40 years

Functions
â–  I2Câ„¢ compatible interface
â–  4,096 bits organized as 512 x 8
■ Extended 2.7V – 5.5V operating voltage
â–  100 KHz or 400 KHz operation
â–  Self timed programming cycle (6ms typical)
â–  "Programming complete" indicated by ACK polling
â–  NM24C17U: Memory "Upper Block" Write Protect pin
