Overview
The CAT25020YI-GT3 is a 2-Kb Serial EEPROM device manufactured by ON Semiconductor. It is internally organized as 256x8 bits and utilizes advanced CMOS technology to significantly reduce power requirements. This device supports the Serial Peripheral Interface (SPI) protocol and is enabled through a Chip Select (CS) input. It includes necessary bus signals such as a clock input (SCK), data input (SI), and data output (SO) lines. Additionally, a HOLD input can be used to pause any serial communication. The device features both software and hardware write protection, including partial and full array protection.
