Microchip Technology's AT24C256-W1-8-11 is a 262Kbit (32K x 8) serial CMOS electrically erasable programmable read-only memory (EEPROM). This device supports I2C bus communication up to 1MHz, offering efficient data transfer. It features hardware and software write protection for data integrity. Applications span industrial control, automotive systems, and consumer electronics, where reliable non-volatile data storage is critical. The AT24C256 series is designed for robust operation across a -40°C to +85°C temperature range and benefits from a wide supply voltage range of 4.5V to 5.5V. Endurance is rated at 1,000,000 write cycles, with a data retention period of at least 40 years. The device also operates at 100kHz at a minimum supply of 1.8V. It utilizes a 32K word organization with 8-bit memory width.
