DS28CZ04 I2C 4k位EEPROM,带有4个输入/输出端口扩展器
DS28CZ04包含有4k位(512 x 8)的EEPROM和4个PIO端口。与器件的通信通过工业标准的I2C和SMBus 接口实现。其存储器组织为256字节的两个段,具备单字节和高达16字节的块写入能力。独立的PIO端口可配置为输入或输出。PIO的上电输出状态可通过非易失性存储器配置。所有PIO可以通过串行总线由用户配置。
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 nonvolatile memory. All PIO may be reconfigured by the user through the serial interface.
