Microchip Technology's 24CW646 series offers a 64Kb serial CMOS EEPROM with an 8K x 8 organization. This device supports I2C serial bus communication, operating with a maximum clock frequency of 1 MHz and a minimum supply voltage of 1.6V up to 5.5V. Featuring a fast access time of 450ns, it provides 200-year data retention at 55°C and 1,000,000 endurance cycles. The 24CW646-I-CS0668 is packaged in a 2x2mm, 16-ball VFBGA with 0.5mm terminal pitch, suitable for surface-mount applications. Its robust design and low standby current make it ideal for industrial, automotive, and consumer electronics where reliable non-volatile memory is critical. Software write protection is implemented.
