The Microchip 25AA640A/25LC640A is a 64Kbit Serial EEPROM that operates via a Serial Peripheral Interface (SPI) with a maximum clock frequency of 10 MHz. It features a memory organization of 8192 x 8 bits and supports a supply voltage range of 1.8V to 5.5V. The device is designed for low power consumption, with a maximum write current of 5 mA and a standby current of 1 ¬µA at 5.5V. This EEPROM supports self-timed erase and write cycles, with a maximum cycle time of 5 ms. It includes block write protection options, allowing users to protect none, 1/4, 1/2, or the entire memory array. The device also features built-in write protection mechanisms, including power-on/off data protection and a write-protect pin. The 25AA640A/25LC640A is rated for high reliability, with an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. It is available in various package types, including SOIC-8, and is suitable for industrial and automotive temperature ranges, from -40¬8C to +85¬8C and -40¬8C to +125¬8C, respectively.
