The onsemi CAT24C21U is a 128 x 8 bit serial CMOS EEPROM from the CAT24C21 series. Featuring an I2C interface, this component operates synchronously with a maximum clock frequency of 400 kHz. It offers a memory density of 1 Kbit, organized as 128 words by 8 bits. The device is housed in a compact, rectangular PDSO8 (TSSOP) package with a 0.65 mm terminal pitch, suitable for surface mounting. Operating within a supply voltage range of 2.5V to 6.0V, it has a typical supply current of 3mA and a write cycle time of 10ms. This EEPROM finds application in industrial control, automotive systems, and consumer electronics where non-volatile data storage is required.
