The onsemi CAT24C21RI-REVB is a 1024-bit CMOS serial EEPROM organized as 128 words by 8 bits. This device employs the industry-standard I2C serial bus interface, supporting clock frequencies up to 400 kHz. Operating within a voltage range of 2.5V to 5.5V, it is suitable for applications requiring non-volatile data storage. The CAT24C21 series is designed for general-purpose data retention in various electronic systems. The component is housed in an 8-lead PDSO (TSSOP) package with a 0.65mm terminal pitch, facilitating compact board layouts. Extended industrial temperature operation from -40°C to +85°C ensures reliability across diverse environments. Typical applications include configuration data storage, parameter settings, and small data logging in consumer electronics, industrial control, and automotive systems. The write cycle time is a maximum of 5ms.
