DS28CZ04 Datasheet | Maxim Integrated

DESCRIPTION The DS28CZ04 bines 4kbit (512 x 8) EEPROM with 4 PIO lines. munication with the device is acplished with an industry standard I²C and SMBus™ interface. The memory is organized as two segments of 256 bytes with single byte and up to 16byte 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.
