FM24C02U/03U – 2K-Bit Standard 2-Wire Bus Interface Serial EEPROM
The FM24C02U/03U devices are 2048 bits of CMOS non-volatile electrically erasable memory designed to conform to the Standard IIC 2-wire protocol. These devices minimize device pin count and simplify PC board layout requirements, with the upper half of the FM24C03U memory optionally write-protected.
The datasheet provides detailed electrical characteristics, including an extended operating voltage range of 2.7V to 5.5V and a maximum clock frequency of 400 KHz. It includes absolute maximum ratings, DC electrical parameters such as active power supply current, AC test conditions for timing waveforms, and package ordering information.
