DS28CZ04 - EEPROM

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 16byte block write capability.

DS28CZ04 4kbit I²C/SMBus EEPROM with Nonvolatile PIO www.maxim-ic.com 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 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.
