MCP2200-I-MQVAO 概述
A USB-to-UART bridge is a category of interface IC (part of the broader USB bridge / serial converter family) that translates USB packet traffic into a simple asynchronous serial stream. These devices let legacy UART-based microcontrollers, sensors, and modules communicate with modern computers that no longer expose physical serial ports, forming a key layer between embedded systems and host-side software in the interface IC hierarchy.
Key features include integrated USB termination resistors, which reduce the external bill of materials by removing the need for discrete pull-up and termination components; 256 bytes of on-chip user EEPROM for storing custom VID/PID and configuration data; and four general-purpose I/O pins that can be toggled by the host for status LEDs, resets, or mode control. Microchip supplies a DLL and configuration utility, so I/O control and device setup require no firmware development on the converter itself.
Architecturally, the MCP2200 handles USB enumeration, endpoint management, and packet-to-byte translation autonomously, appearing to the host as a standard HID-class device. Because HID drivers are built into Windows, Linux, and macOS, deployment is driverless. The UART side operates with standard asynchronous framing, and the device supports baud rate configuration via the Microchip configuration tool.
Typical applications include adding USB connectivity to MCU boards that only expose UART, debug consoles for embedded Linux and FPGA boards, factory automation and point-of-sale equipment, and configuration interfaces for industrial sensors. The 20-VQFN footprint suits compact designs where board area is limited.
Design consideration: the MCP2200 enumerates as HID rather than CDC/ACM (virtual COM port), so host software must speak the Microchip HID protocol or use the supplied DLL rather than a standard serial port API; plan the PC-side software stack accordingly.
This page adds value beyond the manufacturer datasheet by consolidating distributor availability, drop-in alternative analysis, comparison tables, and practical design notes in one place.

典型应用
MCP2200-I-MQVAO 适用于 6 应用s: Adding USB Connectivity to MCU Boards, Embedded Debug and Console Interfaces, Industrial Automation and Field Equipment, Point-of-Sale and Retail Terminals, Sensor and IoT Gateway Configuration Ports, Test and Measurement Instrument Panels.
Adding USB Connectivity to MCU Boards
The MCP2200 fits this application because its UART-side interface connects directly to any MCU TX/RX pair without protocol translation firmware, and the integrated USB termination resistors remove two to three external components that competing bridges require on the USB D+/D- lines. In a typical design the MCU UART runs at the configured baud rate while the MCP2200 handles USB 2.0 full-speed enumeration, packetization, and buffering autonomously. Because it enumerates as HID, end users plug in the board and communicate immediately on Windows, Linux, and macOS with zero driver installation - a significant field-deployment benefit. Trade-off: host software must use the Microchip DLL or HID API rather than a standard COM-port API, so plan the PC-side application accordingly. The 20-VQFN 5x5 mm footprint suits compact microcontroller boards where a full USB bridge chip plus crystal would not fit.
推荐
Embedded Debug and Console Interfaces
Debug consoles benefit directly from the MCP2200's driverless HID enumeration: an engineer attaches a development board to any office or lab PC and gets an immediate UART console link without installing vendor drivers, which matters in locked-down corporate environments without admin rights. The device translates USB packets to asynchronous serial bytes transparently, so bootloaders, U-Boot, and FPGA soft-core consoles work unchanged. The four GPIO pins are commonly used to drive a target reset line or a bootloader-entry signal, letting the host restart the target from the debug tool. The 256-byte EEPROM stores a custom serial number per board, so multiple boards on one host keep stable device identities. Performance consideration: HID polling limits sustained throughput versus CDC-class bridges, so it suits console traffic better than bulk data streaming.
推荐
Industrial Automation and Field Equipment
In industrial automation, legacy equipment frequently exposes only a UART service port while modern service laptops have USB only - the MCP2200 bridges exactly this gap. Its HID-class, driverless operation is valuable on factory-floor PCs managed by IT where driver installation is restricted. The 256-byte EEPROM allows a custom VID/PID so service software can auto-detect the correct tool among many USB devices plugged into the same host. The four GPIO channels can switch status LEDs or read a door-interlock signal reported alongside the serial stream. The 20-VQFN exposed-pad package provides good thermal and ground connection for noise-prone factory environments. Performance consideration: verify baud rate and isolation requirements; the MCP2200 provides no galvanic isolation, so an external isolator should be added for long or noisy field wiring.
推荐
Point-of-Sale and Retail Terminals
Point-of-sale terminals, receipt printers, and barcode scanner bases historically used RS-232 UART links; the MCP2200 gives designers a low-component-count path to USB while reusing the existing UART firmware. Integrated USB termination resistors reduce BOM cost across high-volume retail hardware, and HID enumeration means plug-and-play setup on standard POS operating systems without per-device driver installation - reducing support calls. The custom VID/PID stored in the 256-byte EEPROM lets POS software enumerate the exact device type reliably on shared USB hubs. The GPIO pins handle peripheral signals such as a cash-drawer kick line or status LED. The compact 20-VQFN (5x5 mm) package fits dense terminal PCBs. Trade-off: HID throughput suits command/response POS traffic; for heavy image or receipt-bitmap streaming, evaluate a CDC-class bridge instead.
推荐
Sensor and IoT Gateway Configuration Ports
IoT gateways and sensor nodes typically ship with a sealed enclosure and one service USB port; the MCP2200 turns that port into a UART configuration channel to the node's main MCU or radio module. The four GPIO pins can hold a module in bootloader mode or switch the node between normal and service power domains, all controlled from a host configuration utility through the Microchip DLL. The 256-byte EEPROM assigns each unit a unique serial number, letting fleet-management software distinguish thousands of deployed gateways on shared test stations. Driverless HID operation simplifies certification on Windows and Linux gateways. The 20-VQFN exposed-pad package with its ground paddle supports the ground integrity expected in RF-adjacent designs. Performance consideration: keep configuration traffic modest, since HID-class polling caps sustained bandwidth.
推荐
Test and Measurement Instrument Panels
Bench instruments, dongles, and calibration adapters use the MCP2200 as a compact USB-to-UART front end for command/response control from PC software. The HID classification keeps the instrument driverless across lab PCs, while the 256-byte EEPROM stores calibration metadata or a device serial number that the instrument software reads over the same USB link. The four GPIO channels drive front-panel LEDs or select attenuator relays in coordination with the serial command stream, removing the need for a separate USB-GPIO chip. The 20-VQFN 5x5 mm footprint allows placement right at the rear-panel USB connector, shortening the D+/D- traces, which the integrated termination resistors make especially easy since no external termination network is required. Trade-off: HID polling latency is acceptable for instrument commands, not for high-rate waveform streaming.

设计说明
Keep the D+ and D- USB traces as short as possible and route them as a matched pair with 90-ohm differential impedance where the stack-up allows. Because the MCP2200 integrates the USB termination resistors, do NOT add external pull-up or termination resistors on D+/D- - duplicating termination is a common layout error that breaks full-speed enumeration. Place 0.1 uF decoupling capacitor close to the VDD pin per the datasheet typical application circuit.
The most frequent integration surprise is the HID device class: the MCP2200 does not appear as a virtual COM port (CDC/ACM), so legacy software written against a serial-port API will not see it. Host code must use the Microchip-supplied DLL or a generic HID library. If a COM-port presentation is mandatory for your software ecosystem, select a CDC-class converter instead before committing the PCB footprint.
The 20-VQFN exposed pad must be soldered to a grounded thermal land pattern with an array of thermal vias - the exposed pad is the primary ground connection, and relying on perimeter pins alone degrades both grounding and EMI performance. The 5x5 mm QFN requires a properly reflowed paste stencil; hand-soldering QFN pads reliably is difficult, so plan for reflow assembly. Add vias under the UART traces to keep the return path continuous.
Estimated: budget supply current for the device plus USB bus-powered operation per the datasheet electrical characteristics; confirm the exact supply current figure and VDD range from the latest Microchip datasheet before finalizing the regulator sizing. Place local decoupling at the VDD pin, and if the board is USB bus-powered ensure the total board current stays within the USB 2.0 unit-load budget for the configured device class.
