Overview
The CAT25512YI-GT3 is a 512-Kb Serial EEPROM device produced by onsemi. It is internally organized as 64Kx8 bits and features a 128-byte page write buffer. The device supports the Serial Peripheral Interface (SPI) protocol and is enabled through a Chip Select (CS) input. Additional bus signals include clock input (SCK), data input (SI), and data output (SO) lines. The HOLD input allows for pausing any serial communication with the device. The CAT25512YI-GT3 also includes software and hardware write protection, as well as on-chip Error Correction Code (ECC) for high reliability applications.
