CAT25256XI Datasheet



The CAT25256XI 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. The device is enabled through a Chip Select (CS) input. In addition, therequired bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25256XI device. The device features software and hardware write protection, including partial as well as full array protection.
