onsemi Integrated Circuits (ICs) - Memory - Memory FM24C09UN

The FM24C09UN is an 8K-bit CMOS non-volatile electrically erasable memory device that operates on a 2-wire IIC bus interface. It supports an operating voltage range of 2.7V to 5.5V and features a maximum clock frequency of 400 KHz. The device includes a hardware write protect feature for the upper half of the memory, ensuring data integrity during critical applications. Typical active current consumption is 200 µA, with standby currents as low as 0.1 µA, making it suitable for low-power applications. The FM24C09UN has a write cycle time of approximately 6 ms and offers an endurance of 1,000,000 write cycles with a data retention period exceeding 40 years. It is available in multiple package types, including 8-pin DIP, SOIC, and TSSOP, and can operate across various temperature ranges, including commercial, extended, and automotive grades. This device is ideal for applications requiring reliable data storage with low power consumption and high endurance.
