Overview
The CAT25640YI-GT3 is a 64-Kb Serial SPI EEPROM device produced by onsemi. This device is internally organized as 8Kx8 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. The device includes necessary bus signals such as clock input (SCK), data input (SI), and data output (SO) lines, along with a HOLD input to pause any serial communication. The CAT25640YI-GT3 is designed with hardware and software write protection, ensuring data integrity and security.
