    16-BIT I/O EXPANDERS WITH I2C & SPI INTERFACE

     

    产品信息

    The MCP23017/MCP23S17 (MCP23X17) device family provides 16-bit, general purpose parallel I/O expansion for I2C bus or SPI applications. The two devices differ only in the serial interface.
    • MCP23017 – I2C interface
    • MCP23S17 – SPI interface
    The MCP23X17 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits (IODIRA/B).  The data for each input or output is kept in the corresponding input or output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.

     

      16-bit input/output port expander with interrupt output

      Cascadable for up to 8 devices on one bus

      25mA sink/source capability per I/O

      Supports up to 10MHz SPI™ clock speeds
