The DS28CZ04 combines 4Kb (512 x 8) EEPROM with 4 PIO lines. Communication with the device is accomplished with an industry standard I²C and SMBus™ interface. The memory is organized as two segments of 256 bytes with single byte and up to 16-byte block write capability. Individual PIO lines may be configured as inputs or outputs. The power-on state of PIO programmed as outputs is stored in nonvolatile memory. All PIO may be reconfigured by the user through the serial interface.
