Microchip 25AA256-I/P are 256 Kbit Serial Electrically Erasable PROMs. 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).

Max. Clock 10 MHz
Low-Power CMOS Technology: - Max. Write Current: 5 mA at 5.5V, 10 MHz, - Read Current: 6 mA at 5.5V, 10 MHz, - Standby Current: 1 μA at 5.5V
Self-Timed Erase and Write Cycles (5 ms max.)
Block Write Protection: - Protect none, 1/4, 1/2 or all of array
Built-In Write Protection: - Power-on/off data protection circuitry, - Write enable latch, - Write-protect pin
