The onsemi CAT25128 SPI Serial CMOS EEPROM features software and hardware write protection, including partial and full array protection. The onsemi CAT25128 Serial CMOS EEPROM is 10 MHz SPI compatible, features 1.8V to 5.5V supply voltage range, and includes a 64-byte page write buffer. This onsemi device is enabled through a Chip Select input. Required bus signals of the CAT25128 EEPROM include clock input, data input, and data output lines. The HOLD input may be used to pause any serial communication with the CAT25128 device. Introduced by Mouser Electronics in January 2008.
