The onsemi CAT24C21JI is a 128x8 bit serial CMOS EEPROM. This memory device operates via an I2C serial bus, supporting a maximum clock frequency of 400 kHz. It features a 1024 bit (128 words x 8 bits) memory organization and requires a supply voltage ranging from 2.5V to 5.5V, with a nominal value of 3V. The CAT24C21JI is housed in an 8-lead PDSO (Small Outline) package with a 1.27mm terminal pitch and a rectangular footprint measuring 4.9mm length and 3.9mm width, with a maximum seated height of 1.75mm. Operating within a temperature range of -40°C to +85°C, this component is suitable for applications in industrial control, automotive systems, and consumer electronics. The maximum write cycle time is 10ms.
