Datasheet - 25LC640

Microchip 25LC640-I/P is a 64 Kbit Serial Electrically Erasable PROM [EEPROM]. The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD).

Low-Power CMOS Technology, Write current: 3 mA, typical, Read current: 500 μA, typical, Standby current: 500 nA, typical
