Microchip Technology's 24CW640T-I-OT is a 64-kilobit serial EEPROM with an 8K x 8 organization, designed for robust data storage. This CMOS device operates via the I2C serial bus with a maximum clock frequency of 1 MHz and a fast 450ns access time. It supports a wide supply voltage range from 1.6V to 5.5V, with a nominal 1.8V operation, and features software write protection. The device offers a data retention of 200 years at 55°C and an endurance of 1 million write cycles. Packaged in a 5-lead PDSO (LSSOP) surface-mount configuration with a 0.95mm terminal pitch, it is suitable for applications requiring compact memory solutions in sectors such as automotive (AEC-Q100 qualified), industrial control, and consumer electronics. The open-drain output and low standby current of 1µA contribute to efficient power management.
