The Microchip Technology AT93C66B-XHM-B is a 4Kb serial EEPROM memory organized as 256 words by 16 bits. This CMOS device communicates via the 3-wire SPI-compatible Microwire interface, enabling operation with a single 4.5V to 5.5V supply or a wider 1.7V to 5.5V range. It boasts a maximum clock frequency of 2MHz and offers a data retention period of 100 years with an endurance rating of 1,000,000 write cycles. The AT93C66B-XHM-B features software write protection and operates across an industrial temperature range of -40°C to +85°C. Housed in an 8-lead TSSOP package with a 0.65mm terminal pitch, this component is suitable for applications in industrial control, automotive systems, and consumer electronics where reliable non-volatile data storage is critical.
