MCP2200 USB-to-UART Serial Converter


Microchip Serial Converter provides an easy-to-use, small-footprint, cost-effective option for adding USB connectivity to existing systems


Microchip Technology - MCP2200 USB-to-UART serial converterMicrochip Technology's MCP2200 USB-to-UART protocol converter, with its low-cost evaluation tool, software libraries, and Windows® based configuration tool, enables designers to quickly and easily add USB connectivity to an application without completely redesigning the system. The whole solution is designed to shorten time to market for a variety of applications in the industrial (e.g. data loggers, instrumentation, data-acquisition systems and smart-card readers) and medical markets (e.g. heart-rate, blood-sugar and blood-pressure monitors) in addition to legacy RS-232 applications.

End users increasingly want to connect embedded applications to PCs for data collection, transfer, and analysis as well as for system networking/connectivity. One of the simplest ways to add this capability to existing systems is via a USB-to-UART protocol converter, such as the MCP2200. By simply connecting the MCP2200 UART interface to any microcontroller UART peripheral, USB connectivity can be added. Additionally, the MCP2200 includes eight general-purpose I/O pins that can be controlled by the PC using the Windows-based configuration tool that comes with the MCP2200. As a result, a wider range of applications can be supported.
