The onsemi CAT24C21WE-REVB is a 128x8 bit serial EEPROM designed for applications requiring non-volatile data storage. This CMOS device operates via a two-wire, bidirectional serial interface, commonly known as I2C. With a memory organization of 128 words by 8 bits, it offers 1 kilobit of storage capacity. The CAT24C21 series supports a maximum clock frequency of 400 kHz, enabling efficient data transfer. It features a wide operating voltage range from 2.5V to 5.5V and operates across an industrial temperature range of -40°C to +125°C. The component is housed in an 8-lead PDSO (Small Outline) package with a 1.27mm pitch, suitable for surface-mount assembly. Key applications include industrial control systems, consumer electronics, and automotive systems where persistent configuration data or operational parameters need to be stored. The write cycle time (tWC) is rated at a maximum of 5ms.
