Overview
The CAT25040VI-GT3JN is a 4-Kb Serial SPI EEPROM device produced by ON Semiconductor. This device is part of the CAT25010/20/40 series, which are internally organized as 512x8 bits. It features a 16-byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input and includes bus signals such as a clock input (SCK), data input (SI), and data output (SO) lines. Additionally, it includes a HOLD input to pause any serial communication and offers both software and hardware write protection, including partial and full array protection.
