Microchip MCP2200T-I/MQ: The Robust USB-to-UART Protocol Converter Bridge Controller

In the realm of embedded systems and IoT device development, establishing a reliable and straightforward communication bridge between a USB host and a UART-based peripheral is a fundamental requirement. The Microchip MCP2200T-I/MQ stands out as a dedicated, highly integrated single-chip solution designed specifically for this critical task. This protocol converter bridge controller simplifies connectivity, enabling seamless data transfer and control, making it an indispensable component for designers and engineers.

The core function of the MCP2200T-I/MQ is to transparently translate USB data packets into UART serial signals and vice versa. It enumerates on the host computer as a standard CDC (Communications Device Class) device, which means it leverages built-in operating system drivers, eliminating the need for custom driver development on most platforms. This plug-and-play capability drastically reduces development time and complexity. The device supports common baud rates, data bits, parity, and stop bits, ensuring compatibility with a vast array of microcontrollers, sensors, and legacy serial devices.

Beyond its primary data conversion role, the MCP2200T-I/MQ integrates valuable additional features that enhance its utility. It includes four general-purpose I/O (GPIO) pins and two dedicated modem control signals (RTS/DTR), which can be configured for handshaking or to control external hardware directly from the USB host. This functionality allows the chip to do more than just data transfer; it can serve as a simple USB-controlled GPIO expander, adding significant value in compact designs.

Housed in a compact 20-pin QFN package, the MCP2200T-I/MQ is engineered for space-constrained applications. Its industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environments, making it suitable for industrial automation, automotive, and consumer applications. The device is also pre-programmed with a unique serial number, facilitating product differentiation and inventory management for manufacturers.

ICGOODFIND: The Microchip MCP2200T-I/MQ is a quintessential bridge component, offering a cost-effective, low-power, and highly reliable method for adding USB connectivity to any design with a UART interface. Its combination of core protocol conversion, integrated GPIO, and driverless operation establishes it as a superior solution for streamlining product development and enhancing functionality.
