Product Introduction

Overview

The CAT25256VI-GT3 is a 256-Kb SPI Serial CMOS EEPROM device produced by onsemi. It is internally organized as 32Kx8 bits and features a 64-byte page write buffer. The device supports the Serial Peripheral Interface (SPI) protocol and is enabled through a Chip Select (CS) input. It includes required bus signals such as clock input (SCK), data input (SI), and data output (SO) lines. Additionally, a HOLD input can be used to pause any serial communication with the device. The CAT25256VI-GT3 is designed for high reliability applications, including automotive, communications, computer, consumer, and industrial systems.
