The CAT24C04YI-GT3 is an integrated non-volatile memory device manufactured by ON Semiconductor. It is a 4K-bit EEPROM (Electrically Erasable Programmable Read-Only Memory) interface with an I2C serial communication protocol. It operates using a 1.8V to 5.5V supply voltage with a maximum current rating of 2.5mA.This memory device is capable of holding up to 4K bits of data. Data storage is non-volatile, ensuring data won’t be lost if power is lost. This device also includes security features such as a write protect pin, which prevents data from being overwritten, and a write-ability detection pin. In addition, the CAT2404YI-GT3 has a low power capability, allowing it to enter a low power mode to reduce power consumption when not in use.The CAT24C04YI-GT3 is ideal for applications such as consumer electronics, electronic voting systems, and mass transit systems. It is also suitable for data logging and medical applications that require non-volatile and secure data storage.
