Overview
The CAT25128 is a 128-Kb Serial CMOS EEPROM device produced by Onsemi. It is internally organized as 16Kx8 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. Additionally, it has a HOLD input to pause serial communication and supports SPI modes (0,0) and (1,1).
