The CAT93C66SI is a 4K-bit Microwire Serial EEPROM memory device designed for high-speed operation at 1 MHz. It operates within a voltage range of 1.8 to 6.0 volts and features selectable memory organization in either 8-bit or 16-bit formats, depending on the ORG pin configuration. The device supports self-timed write cycles with auto-clear functionality and includes both hardware and software write protection mechanisms. Manufactured using advanced CMOS technology, the CAT93C66SI is rated for 1,000,000 program/erase cycles and offers a data retention period of up to 100 years. It is available in multiple package types, including 8-pin DIP, SOIC, TSSOP, and TDFN, making it versatile for various applications. The device also includes power-up inadvertent write protection and is suitable for commercial, industrial, and automotive temperature ranges. Engineers may find this product suitable for applications requiring reliable non-volatile memory with low power consumption and high endurance.
