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.
