Overview
The CAT25640VI-GT3 is a Serial 64-Kb EEPROM device produced by onsemi. It is internally organized as 8Kx8 bits and features a 64-byte page write buffer. The device supports the Serial Peripheral Interface (SPI) protocol and operates within a supply voltage range of 1.8 V to 5.5 V. It is enabled through a Chip Select (CS) input and includes bus signals such as clock input (SCK), data input (SI), and data output (SO) lines. Additionally, it includes a HOLD input for pausing serial communication and offers both software and hardware write protection.
