The onsemi CAT24C21YE-G is a 128 x 8 bit serial CMOS EEPROM with a 1024 bit memory density. This device utilizes an I2C serial interface, supporting standard and fast mode operation, controlled via a specific I2C control byte pattern (1010XXXR). Designed for robust operation, it offers a data retention time of at least 100 years and an endurance rating of 1,000,000 write cycles. The component operates across a wide temperature range from -40°C to +125°C. Packaged in a compact, rectangular TSSOP8 (R-PDSO-G8) with a 0.635mm terminal pitch, it is suitable for surface-mount applications. Typical industries leveraging this device include industrial control, consumer electronics, and automotive systems requiring reliable non-volatile memory for configuration data or operational parameters. The CAT24C21 series provides a low standby current of 1µA and a maximum supply current of 2mA.
