Microchip Technology, Inc. Memory 25AA256-E/MF

The Microchip Technology 25AA256/25LC256 is a 256 Kbit Serial Electrically Erasable PROM (EEPROM) that utilizes a Serial Peripheral Interface (SPI) for communication. It operates within a voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz. The memory is organized as 32,768 x 8 bits and features a 64-byte page size for efficient data handling. This device is designed with low-power CMOS technology, achieving a maximum write current of 5 mA and a read current of 6 mA at 5.5V. It includes self-timed erase and write cycles with a maximum duration of 5 ms. The 25AA256/25LC256 also offers block write protection options, allowing users to protect none, 1/4, 1/2, or the entire memory array. The product is rated for high reliability, with an endurance of 1,000,000 erase/write cycles and a data retention period exceeding 200 years. It is also compliant with RoHS standards and qualified for automotive applications under AEC-Q100. The device is available in various package types, including PDIP, SOIC, DFN, and TSSOP, making it suitable for a wide range of applications.
