The DS28CZ04 combines 4kbit (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.
