INTRODUCTION
This application note discusses using the MCP23008
and MCP23S08 GPIO Expanders with a 6-pin
PIC10F202 microcontroller unit (MCU). The discussion
is based on the MCP23X08 Evaluation Board, P/N:
MCP23008DM.
An I/O expander is used to increase the I/O capability
of microcontrollers. The microcontroller performs the
master functions for the serial interface (either through
the appropriate hardware interface or via a software-
implemented interface). The MCP23X08 acts as a
slave device.
The MCP23X08 8-bit GPIO family consists of two
devices which differ only in the serial interface:
• MCP23008 - I
2
C™ interface
• MCP23S08 - SPI™ interface
In addition to the serial interface listed, the MCP23X08
implements the following features:
• 8-bit GPIO bidirectional port
• Hardware address pins for allowing multiple
MCP23X08 devices on the same bus
• Interrupt output with programmable polarity and
function
• Configurable interrupt sources
• Reset input
• Polarity inversion capability for automatically
inverting the polarity on the port.
This application note does not detail all of the features
of the MCP23X08. Refer to the MCP23008/MCP23S08
Data Sheet, “8-Bit I/O Expander with Serial Interface”
(DS21919), for more information.
The PIC10F202 communicates with the MCP23008
using the I
2
C protocol, and with the MCP23S08 using
the SPI protocol.
