Product Summary

The CAT25256 is a 256.Kb Serial CMOS EEPROM device
internally organized as 32Kx8 bits. This features a 64.byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. It is enabled through a Chip Select (CS) input. In addition, therequired bus signals are clock input (SCK), data input (SI) and dataoutput (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25256 device.The device featuressoftware and hardware write protection, including partial as well as full array protection.
