The onsemi CAT24C21YE is a 1Kbit serial CMOS EEPROM featuring a memory organization of 128 words by 8 bits. It operates via the I2C serial bus with a maximum clock frequency of 400 kHz. This device supports a supply voltage range of 2.5V to 5.5V and offers a data retention time exceeding 100 years, with an endurance rating of 1 million write cycles. The CAT24C21YE is housed in a compact 8-lead TSSOP package (JESD30 code R-PDSO-G8) with a 0.65mm pitch, suitable for surface mounting. It is AEC-Q100 qualified, making it appropriate for automotive and industrial applications where reliable non-volatile data storage is critical. The I2C control byte format is 1010XXXR. Operating temperature range is -40°C to +125°C.
