Overview
The CAT24C04YI-GT3 is a 4-Kb I²C serial EEPROM device produced by onsemi. It is organized internally as 32 pages of 16 bytes each, supporting both the Standard (100 kHz) and Fast (400 kHz) I²C protocol. This device is designed for applications requiring non-volatile memory storage and is particularly useful in systems where data needs to be retained even when power is turned off.
The device operates within a supply voltage range of 1.7 V to 5.5 V and features low power CMOS technology, ensuring minimal power consumption. It also includes hardware write protection for the entire memory and Schmitt triggers and noise suppression filters on the I²C bus inputs (SCL and SDA).
