The Microchip 24AA256/24LC256/24FC256 is a 256 Kbit Serial Electrically Erasable PROM (EEPROM) designed for low-power applications. It operates within a voltage range of 1.7V to 5.5V and supports a maximum clock frequency of 400 kHz. The device features a memory configuration of 32K x 8 bits and allows for both random and sequential reads. It includes a page write capability of up to 64 bytes and can be cascaded with up to eight devices on the same bus, providing a total address space of 2 Mbit. The EEPROM is available in multiple package types, including TSSOP-8, and is compliant with RoHS standards. It offers low power consumption with a maximum read current of 400 µA and a standby current of 1 µA. The device is rated for over one million erase/write cycles and has a data retention period exceeding 200 years. It also features hardware write protection and ESD protection greater than 4000V, making it suitable for a variety of applications in industrial and automotive environments.
