Overview
The CAT25256YI-GT3 is a 256-Kb SPI Serial CMOS EEPROM device manufactured by onsemi. This device is internally organized as 32k x 8 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, along with clock input (SCK), data input (SI), and data output (SO) lines. The HOLD input allows for pausing any serial communication with the device. The CAT25256YI-GT3 is designed for high reliability applications, including automotive, communications, computer, consumer, and industrial systems.
