The Microchip 25AA256/25LC256 is a 256 Kbit Serial EEPROM that operates within a temperature range of -40¬8C to +125¬8C, making it suitable for automotive applications as it is AEC-Q100 qualified. It features a 32,768 x 8-bit memory organization and communicates via a Serial Peripheral Interface (SPI) with a maximum clock frequency of 10 MHz. The device supports low-power operation with a maximum write current of 5 mA and a read current of 6 mA at 5.5V. It includes built-in write protection mechanisms and offers endurance of up to 1,000,000 erase/write cycles with data retention exceeding 200 years. The EEPROM is available in various package types, including 8-lead PDIP and SOIC, and is RoHS compliant.
