Product Overview

The MCP23X17EV is a MCP23X17 16bit GPIO expander evaluation board, demonstrates simple input/output functionality of the MCP23017 I2C interface and the MCP23S17 SPI interface. Both the devices are connected to the same inputs and outputs and selector switch is used to select which device the PICmicro controls. A mux is used to route the serial (I2C or SPI) from the PICmicro to the MCP23X17. Four MCP23X17 pins are configured as inputs and connected to four momentary push buttons. The remaining twelve GPIO pins are configured as outputs and connected to LEDs. Each button causes the LEDs to sequence in a predetermined pattern. The MCP23X17 is provided in small, space saving 18 lead SSOP packages.
  • Demonstrates the MCP23X17 devices in a simple I/O application
  • ICSP header for the PICmicro allows users to Customise firmware to further evaluate the MCP23X17
  • Jumpers and headers allow the MCP23X17 to connect directly to custom applications for prototype work
  • Can be powered from a 3.0V to 5V DC power source (connected to the 5V and GND test points)
