The Microchip 25AA040A/25LC040A is a 4 Kbit Serial EEPROM organized as 512 x 8 bits, designed for low-power applications. It operates within a voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz. The device features a write page mode allowing up to 16 bytes to be written in a single operation, and it includes self-timed erase and write cycles with a maximum duration of 5 ms. This EEPROM provides robust data protection with built-in write protection features, including a write-protect pin and power-on/off data protection circuitry. It has a high endurance rating of 1,000,000 erase/write cycles and offers data retention exceeding 200 years. The device is available in an 8-pin TSSOP package and is RoHS compliant, making it suitable for various industrial and automotive applications with operating temperature ranges from -40¬8C to +125¬8C.
