The Microchip Technology 25AA640-I/SN is a 64 Kbit Serial Electrically Erasable PROM (EEPROM) utilizing Low-Power CMOS technology. It is accessed via a standard Serial Peripheral Interface (SPI) compatible serial bus, requiring SCK, SI, and SO lines, with control managed by a Chip Select (CS) input. The device supports sequential reads and features built-in write protection mechanisms, including a write-protect pin.
This EEPROM is organized as 8192 x 8 bits with a 32-byte page size and a maximum write cycle time of 5 ms. It operates within a voltage range of 1.8V to 5.5V and supports an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a typical write current of 3 mA, a typical read current of 500 μA, and a very low typical standby current of 500 nA. Reliability is high, with data retention exceeding 200 years and ESD protection greater than 4000V.
The 25AA640-I/SN is available in an 8-pin SOIC package, suitable for surface mounting. Its features make it suitable for various applications requiring non-volatile memory storage.
