CAT25640VI-GT3

Product Summary

The CAT25640VI-GT3 is a 64-Kb Serial CMOS EEPROM device internally organized as 8Kx8 bits. This features a 64-byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The CAT25640VI-GT3 is enabled through a Chip Select (C¯¯S) input. In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The H¯¯O¯L¯D¯ input may be used to pause any serial communication with the CAT25640 device. The CAT25640VI-GT3 features software and hardware write protection, including partial as well as full array protection.
