Overview
The CAT25256LI-GC is a 256-Kb 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 bus signals such as clock input (SCK), data input (SI), and data output (SO) lines, as well as a HOLD input to pause any serial communication. The CAT25256LI-GC is designed with both software and hardware write protection, including partial and full array protection, and includes On-Chip ECC (Error Correction Code) for high reliability applications.
