Overview
The CAT24C04C4ATR is a 2-Kb I2C Serial EEPROM device produced by onsemi. This device is organized internally as 32 pages of 16 bytes each, supporting both Standard (100 kHz) and Fast (400 kHz) I2C protocols. It is designed for low-power CMOS technology and features a wide supply voltage range of 1.7 V to 5.5 V. The device includes a 16-byte page write buffer and hardware write protection for the entire memory. It also incorporates Schmitt triggers and noise suppression filters on the I2C bus inputs (SCL and SDA) to ensure reliable data transmission.
