The Microchip MCP2200T-I/SS: A Robust USB-to-UART Serial Bridge Controller

In the realm of embedded systems and IoT development, establishing a reliable and straightforward communication link between a host computer and a microcontroller is a fundamental requirement. The Microchip MCP2200T-I/SS stands out as a premier solution, offering a highly integrated and cost-effective method for adding USB capability to any embedded design.

This powerful little controller functions as a USB 2.0 full-speed compliant bridge, seamlessly translating USB data packets into a simple UART serial interface. Its core function is to eliminate the complexity of USB protocol development, allowing engineers to focus on their application rather than low-level driver coding. The device is configured as a CDC (Communications Device Class) device, which means it is recognized by most major operating systems, including Windows, macOS, and Linux, as a virtual COM port. This allows existing terminal emulators and software to communicate with the target hardware without needing custom drivers.

Key features that make the MCP2200T-I/SS exceptionally versatile include its integrated USB transceiver and internal oscillator. The inclusion of these components drastically reduces the external part count, saving both board space and Bill of Materials (BOM) cost. Furthermore, the device offers eight general-purpose I/O (GPIO) pins and a configurable Baud Rate Generator, providing additional flexibility for system control beyond simple data transfer. Housed in a compact SSOP-20 package, it is ideal for space-constrained applications.

The MCP2200T-I/SS is designed for robustness and ease of implementation. It supports data transfer rates up to 1 Mbps, making it suitable for a wide array of applications, from industrial control and data acquisition to consumer electronics and DIY projects. Its ability to provide a quick and stable plug-and-play serial connection accelerates prototyping and simplifies final product design.

ICGOODFIND: The Microchip MCP2200T-I/SS is an indispensable tool for developers, providing a hassle-free, reliable, and feature-rich bridge between the universal world of USB and the foundational UART protocol, all while minimizing design overhead and cost.
