The onsemi CAT24C21PE is a 1Kbit serial CMOS EEPROM organized as 128 words by 8 bits. This device operates via an I2C serial bus, supporting clock frequencies up to 400 kHz. It features a wide operating voltage range of 2.5V to 5.5V and a temperature range of -40°C to +125°C. The CAT24C21PE is housed in an 8-lead PDIP package with a 2.54mm terminal pitch, suitable for through-hole mounting. Typical applications include industrial control systems, automotive electronics, and consumer devices requiring non-volatile data storage. The maximum write cycle time (tWC) is 5ms.
