DS28CZ04

4kbit I²C/SMBus EEPROM

with Nonvolatile PIO

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

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 non-

volatile memory. All PIO may be reconfigured by the

user through the serial interface.
