Microchip Technology's 93C66AT-E-SN is a 4 Kbit serial CMOS EEPROM, organized as 512 words by 8 bits. This component operates over a wide voltage range from 1.8V to 5.5V, with a nominal supply voltage of 2.5V. It supports a maximum clock frequency of 1MHz and features the Microwire serial bus interface. The device offers 1,000,000 endurance cycles and 200 years of data retention. Designed for surface mounting, it is housed in an 8-lead PDSO package (SOP8) with a 1.27mm terminal pitch. Applications include automotive, industrial control, and consumer electronics where reliable non-volatile data storage is required. The 93C66 series supports software write protection and a toggle bit for efficient status monitoring.
