Microchip Technology's AT24C256 is a 262,144-bit serial CMOS EEPROM, organized as 32K x 8 bits. This device operates via a two-wire serial interface, supporting I2C protocols up to 1 MHz. It features a robust endurance of 1,000,000 write cycles and a data retention of 40 years. The AT24C256BU2-UU-T is housed in an 8-lead PBGA package with a 0.75mm terminal pitch, supporting a wide supply voltage range from 1.8V to 5.5V. Applications include industrial control, automotive systems, and consumer electronics requiring non-volatile data storage. Hardware and software write protection are implemented. The maximum operating temperature is 85°C.
