Overview
The CAT24AA08TDI-GT3 is an 8-kb CMOS Serial EEPROM device produced by onsemi. It is internally organized as 1024x8 bits and features a 16-byte page write buffer. This device supports 100 kHz, 400 kHz, and 1 MHz I2C protocols, making it versatile for various applications. Unlike the CAT24C04/24C08, the CAT24AA08 does not have external address pins, making it suitable for use as a single device on the I2C bus.
