The 93C66B-E/MS is a 4Kbit low-voltage serial EEPROM from Quarktwin Technology Ltd., designed for applications requiring nonvolatile memory. It operates within a voltage range of 4.5V to 5.5V and supports a 16-bit word size. The device features low-power CMOS technology, making it suitable for energy-efficient designs. It includes self-timed erase and write cycles, automatic erase before write, and a power-on/off data protection circuit. The EEPROM supports an industry-standard 3-wire serial I/O interface and has a data retention capability exceeding 200 years, with a durability of 1,000,000 erase/write cycles. The device is available in various package types, including 8-lead MSOP, and is compliant with RoHS standards. It operates within industrial temperature ranges of -40¬8C to +85¬8C and automotive ranges of -40¬8C to +125¬8C, making it versatile for different environmental conditions.
