Overview
The CAT25256YI-GT3 is a 256-Kb Serial EEPROM device produced by onsemi. It is internally organized as 32Kx8 bits and supports the Serial Peripheral Interface (SPI) protocol. The device features a 64-byte page write buffer 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. The CAT25256YI-GT3 includes software and hardware write protection, as well as on-chip Error Correction Code (ECC) for high reliability applications.
