The Microchip Technology AT25256B-PU is a 32K x 8 (262 Kbit) serial CMOS EEPROM. This device utilizes the SPI serial bus interface, supporting clock frequencies up to 20 MHz. It offers dual supply voltage ranges: 2.5V to 5.5V at 10 MHz operation and 1.8V to 5.5V at 5 MHz operation. The AT25256B-PU is housed in a through-hole PDIP8 package with a standard 0.300-inch body width and 0.100-inch terminal pitch. Key features include a maximum write cycle time of 5ms and an operating temperature range of -40°C to +85°C. This component is suitable for applications in industrial control, consumer electronics, and automotive systems requiring reliable non-volatile data storage.
