Microchip Technology’s 24CW643T-I-SN is a 64Kb serial EEPROM memory device organized as 8K x 8 bits. This CMOS component operates via the I2C serial bus with a maximum clock frequency of 1MHz and features a fast 450ns access time. It supports a wide supply voltage range from 1.6V to 5.5V, with a nominal operation at 1.8V, and offers software write protection. The device boasts 1,000,000 endurance cycles and a data retention of over 200 years at 55°C. The 24CW643 series is suitable for applications in industrial control, consumer electronics, and automotive systems requiring non-volatile data storage. Packaged in a PDSO8 (SOP8) surface-mount configuration with an 8-pin interface and open-drain outputs, it conforms to the R-PDSO-G8 standard.
