The 93C66CT-E/ST is a 4Kbit low-voltage serial EEPROM from Quarktwin Technology Ltd., designed for low-power applications. It operates within a voltage range of 4.5V to 5.5V and supports both 8-bit and 16-bit word sizes, selectable via an ORG pin. The device features self-timed erase and write cycles, including an automatic erase before write function, ensuring efficient data management. It is rated for 1,000,000 erase/write cycles and offers data retention exceeding 200 years, making it suitable for long-term storage needs. The EEPROM is compliant with RoHS standards and is available in various package types, including 8-lead PDIP and SOIC, as well as advanced packaging options. It operates effectively across a temperature range of -40¬8C to +125¬8C for automotive applications and -40¬8C to +85¬8C for industrial applications. The device also includes power-on/off data protection circuitry and a ready/busy status signal, enhancing its reliability in various applications.
