Microchip Technology's 93LC66AT-I-SM is a 4Kb serial CMOS EEPROM organized as 512 words by 8 bits. This device operates with a synchronous Microwire interface, supporting clock frequencies up to 2 MHz. It features a robust endurance rating of at least 1,000,000 erase/write cycles and data retention exceeding 200 years, ensuring long-term reliability. The 93LC66 series component is housed in an 8-lead PDSO (SOP) package, suitable for surface-mount applications. Operating over an industrial temperature range of -40°C to +85°C, it requires a supply voltage from 2.5V to 6.0V. Typical applications include automotive systems, industrial controls, and consumer electronics requiring non-volatile data storage. Software write protection is supported.
