The AT25256B-MAPDGV-T is a 256 Kbit (32,768 x 8) Serial EEPROM from Quarktwin Technology Ltd., designed for automotive applications. It features a Serial Peripheral Interface (SPI) compatible with modes 0 and 3, allowing for flexible integration into various systems. The device operates within a voltage range of 1.7V to 5.5V and supports an extended temperature range of -40¬8C to +125¬8C, making it suitable for harsh environments. This EEPROM supports a maximum clock rate of 5 MHz and includes a 64-byte page mode for efficient data writing. It offers block write protection options, allowing users to protect portions of the memory array, and features a write-protect pin for additional security. The write cycle is self-timed, with a maximum duration of 5 ms, ensuring quick data updates. The AT25256B-MAPDGV-T is automotive AEC-Q100 qualified, ensuring high reliability with an endurance of 1,000,000 write cycles and a data retention period of up to 100 years. It is available in a compact 8-Pad UDFN package, which is lead-free, halide-free, and compliant with RoHS standards. This product is ideal for engineers seeking a reliable and robust memory solution for automotive applications.
