Microchip Technology's AT24C256CW-SH-T is a 262,144-bit (32K x 8) CMOS serial EEPROM. This device operates via an I2C-compatible interface, supporting clock frequencies up to 400 kHz. It offers robust data retention of at least 40 years and a high endurance of 1 million write cycles. The AT24C256 series supports both hardware and software write protection for data integrity. Designed for a wide operating voltage range from 1.8V to 5.5V, it is suitable for applications requiring low standby current (1 µA max) and efficient operation (3 mA max during writes). The component is housed in an 8-lead Small Outline Package (SOP) with a 1.27 mm terminal pitch, ideal for surface-mount assembly. Typical applications include industrial control, consumer electronics, and automotive systems. The I2C control byte format is 1010DDDR.
