The onsemi CAT24C21YI-GT3 is a 1024-bit serial CMOS EEPROM organized as 128 words by 8 bits. It operates via the I2C serial bus interface, supporting clock frequencies up to 400 kHz. This device offers robust data retention exceeding 100 years and an endurance rating of 1 million write cycles. The I2C control byte format is 1010XXXR. The CAT24C21 series component is housed in a compact R-PDSO-G8 package (TSSOP8), featuring a rectangular shape with a 0.65 mm terminal pitch and a seated height of 1.2 mm. Its operating temperature range is from -40°C to +85°C, with a supply voltage range of 2.5V to 5.5V. Typical applications include consumer electronics, industrial control systems, and automotive electronics requiring non-volatile data storage.
