GENERAL DESCRIPTION
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.
