The Microchip 25AA040A/25LC040A is a 4 Kbit Serial EEPROM designed for use in industrial and automotive applications, with an operating temperature range of -40¬8C to +85¬8C for industrial and up to +125¬8C for automotive. It features a 512 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 and read current of 5 mA at 5.5V, and a standby current of 5 ¬µA. It includes write protection features, such as a write-protect pin and power-on/off data protection circuitry. The EEPROM has a high endurance rating of 1,000,000 erase/write cycles and offers data retention exceeding 200 years. It is available in various package types, including 8-lead PDIP, SOIC, MSOP, TSSOP, DFN, and SOT-23, and is compliant with RoHS standards.
