Overview
The CAT24C16C4ATR is a 16 kb CMOS Serial EEPROM device manufactured by onsemi. This device is organized internally as 128 pages of 16 bytes each, totaling 2048 x 8 bits. It supports both the Standard (100 kHz) and Fast (400 kHz) I2C protocol, making it versatile for various applications. The device features a 16-byte page write buffer, allowing data to be written in one internal write cycle after loading the buffer. Data is read by providing a starting address and then shifting out data serially while automatically incrementing the internal address count. The CAT24C16C4ATR also includes external address pins, enabling up to eight devices to be addressed on the same bus.
