The onsemi CAT93C66LI-1-8-G is a 4Kb serial CMOS EEPROM organized as 256 words by 16 bits. This component features a Microwire serial interface for efficient data transfer and supports software write protection. With a robust endurance of 1,000,000 write cycles and a data retention of at least 100 years, it is suitable for applications requiring reliable non-volatile storage. The CAT93C66 series operates across a temperature range of -40°C to +85°C. This through-hole DIP-8 package variant is commonly found in industrial control systems, consumer electronics, and automotive applications where persistent data logging or configuration storage is critical. Its low standby current of 10µA and maximum operating current of 3mA make it power-efficient for embedded designs.
