Overview
The CAT25256VI-GT3C is a 256-kb SPI Serial CMOS EEPROM produced by onsemi. This device is internally organized as 32kx8 bits and features a 64-byte page write buffer. It supports the Serial Peripheral Interface (SPI) protocol and is enabled through a Chip Select (CS) input, with additional bus signals including clock input (SCK), data input (SI), and data output (SO) lines. The HOLD input allows for pausing any serial communication with the device. The CAT25256VI-GT3C is designed for high reliability applications, including automotive, communications, computer, consumer, and industrial systems.
