Microchip Technology presents the 24CW644-E-SN66KVXX, a serial CMOS EEPROM from the 24CW644 series. This component offers an 8K x 8 memory organization with a density of 64 Kbits and features a maximum access time of 450 ns. Operating via the I2C serial bus with a maximum clock frequency of 1 MHz, it supports a wide supply voltage range from 1.6V to 5.5V, with a nominal operating voltage of 1.8V. The device is designed for endurance with 1 million write cycles and provides 200 years of data retention at 55°C. Packaged in an 8-lead PDSO (SOP) surface-mount configuration with a 1.27mm terminal pitch, it meets AEC-Q100 standards. Applications span automotive, industrial, and consumer electronics sectors requiring non-volatile data storage. Software write protection is implemented.
