Microchip Technology's 25AA040XT-E-ST is a 4Kb Serial EEPROM with a memory organization of 512 words by 8 bits. This CMOS device operates via a standard SPI serial interface, supporting clock speeds up to 10 MHz. It features hardware and software write protection, and a data retention capability exceeding 200 years. The endurance rating is 1 million write cycles.
Designed for robust operation, the 25AA040XT-E-ST operates across an industrial temperature range of -40°C to +125°C. It is housed in a compact 8-lead TSSOP (Thin Shrink Small Outline Package) with a 0.635mm terminal pitch, suitable for surface-mount applications. This component finds utility in automotive, industrial, and consumer electronics sectors requiring reliable non-volatile data storage. Its low standby current of 2µA and active supply current of 5mA make it suitable for power-sensitive designs.
