The CAT93C66YI-GT3 is a 4 kb Microwire Serial CMOS EEPROM from Quarktwin Technology Ltd. It features a selectable memory organization, allowing configuration as either 256 registers of 16 bits or 512 registers of 8 bits. The device operates at a supply voltage range of 1.8 V to 5.5 V and supports high-speed operation up to 2 MHz. It includes features such as sequential read, software write protection, and power-up inadvertent write protection. The CAT93C66YI-GT3 is designed for low power consumption, with a typical power supply current of 1 mA during write operations and 500 ¬µA during read operations. It has a reliability rating of 1,000,000 program/erase cycles and 100 years of data retention. The product is available in an 8-lead TSSOP package and is compliant with RoHS standards. This EEPROM is suitable for industrial applications, operating within a temperature range of -40¬8C to +85¬8C.
