The onsemi CAT24WC66LA-1-8-G is a 64Kb serial CMOS EEPROM with an 8K x 8 memory organization. This device operates via an I2C serial interface, supporting clock frequencies up to 400kHz. It features a supply voltage range from 1.8V to 5.5V and a typical operating temperature range of -40°C to +105°C. The CAT24WC66 series is designed for applications requiring reliable, non-volatile data storage, including automotive systems, industrial controls, and consumer electronics. Endurance is rated at 1,000,000 write cycles, with data retention exceeding 100 years. The component is housed in an 8-lead PDIP package, specified by JESD-30 code R-PDIP-T8, with a terminal pitch of 2.54mm. Hardware write protection is implemented for data integrity.
