The CAT24M01WI-GT3 is a 1 Mb I2C CMOS serial EEPROM designed for reliable data storage. It supports Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C protocols and features a 256-byte page write buffer. This device operates over a supply voltage range of 1.8 V to 5.5 V and an industrial temperature range of -40°C to +85°C. Additional features include hardware write protection, on-chip ECC for high reliability, and low power consumption. With an endurance of 1,000,000 program/erase cycles and 100-year data retention, it is well-suited for applications requiring long-term, non-volatile memory.
