ADM00276 MCP2200 Isolated USB to UART Demo Board

The MCP2200 USB to UART with Isolation Demo Board is a USB to UART development and evaluation board for the MCP2200 device. This board is powered from the host’s USB port. Two of the MCP2200 GPIO pins (GP6 and GP7) are connected to LEDs used to indicate the USB to UART traffic when the associated pins are configured as TxLED and RxLED pins, respectively. The isolated side is powered
externally with 3V to 5.5V. The board offers 3.75 kV AC of electrical isolation for power and UART signals.

Microchip Technology Inc. provides a software package to be used with this board that can be downloaded from Microchip’s web site. This PC software is used to evaluate/demonstrate the MCP2200 as a Virtual Com Port (VCP) device. This software also allows custom device configurations.

A DLL is included to allow the development of the custom configurations and software applications to control the GPIOs, that can be downloaded from the product/board web page.

• Dedicated Tx LED (green) and Rx LED (red) to indicate the USB to UART traffic
• Isolated power LED (green) that indicates the presence of power on the isolated side
• Mini-USB connector
• 6-pin PICkit™ Serial header with the UART (Tx and Rx) signals and power signals (VDD and GND)
• Isolated transceiver powered externally from the isolated side with 3V to 5.5V that can be used as a voltage level translator
