The Microchip 25AA040A/25LC040A is a 4 Kbit Serial EEPROM that operates at a maximum clock frequency of 10 MHz. It features a memory organization of 512 x 8 bits and supports a supply voltage range of 1.8V to 5.5V for the 25AA040A and 2.5V to 5.5V for the 25LC040A. The device is designed for low power consumption, with a maximum write current of 5 mA and a standby current of just 5 ¬µA at 5.5V. This EEPROM supports write page mode for up to 16 bytes and offers self-timed erase and write cycles with a maximum duration of 5 ms. It includes block write protection options and built-in write protection features such as power-on/off data protection circuitry and a write-protect pin. The device is rated for high reliability, with an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. The operating temperature ranges are from -40¬8C to +85¬8C for industrial applications and -40¬8C to +125¬8C for automotive applications. The product is available in various package types, including the SOT-23-6, and is compliant with RoHS standards.
