Microchip Technology's 24CW640-I-Q4B is a 64-kilobit serial EEPROM featuring an 8K x 8 memory organization. This CMOS device operates via the I2C serial bus with a maximum clock frequency of 1 MHz and a fast 450 ns access time. It supports a wide supply voltage range from 1.6V to 5.5V with a nominal 1.8V operation, and a low standby current of 1 µA. The 24CW640-I-Q4B offers 1 million endurance cycles and a data retention of 200 years at 55°C. Its PDSO8 package is suitable for surface-mount applications. This component finds utility in industrial control, automotive systems, and consumer electronics requiring reliable non-volatile data storage. Software write protection is implemented for enhanced data integrity.
