MCP2200-I-SS Descripción general
A USB-to-UART bridge is a type of interface IC that sits between a host PC's USB port and a microcontroller or system UART. In the product hierarchy, it belongs to the USB bridge controller family within interface ICs and serial communication devices. Its role is to translate USB full-speed packets into asynchronous serial data, letting legacy UART-based designs gain USB connectivity without firmware changes, appearing to the host as a virtual COM port.
Key features include full-speed USB 2.0 compliance, integrated USB termination resistors that reduce the external BOM, hardware flow control via RTS/CTS, and 8 GPIO pins configurable through vendor software or EEPROM defaults. The 256-byte on-chip EEPROM stores VID/PID, product strings and power parameters, allowing custom USB identities without external memory.
Technically, the MCP2200 uses CMOS technology, integrates the USB transceiver and a 3.3V/5V-tolerant interface, and enumerates on the host using a virtual COM port driver supplied by Microchip for Windows, Linux and macOS. The UART interface connects directly to an MCU's TX/RX pins, while configuration utilities allow GPIO direction, polarity and EEPROM values to be set at runtime.
Typical applications include adding USB connectivity to embedded MCU boards, industrial equipment service ports, point-of-sale terminals, and PC-based instrument front ends where a UART link with a few extra control lines is needed.
A key design consideration is that the MCP2200's baud rate range and buffer sizes must be checked against your MCU link, and USB bus power budgeting should follow the values programmed in the EEPROM. There is no true pin-to-pin drop-in replacement in the same 20-SSOP footprint from other vendors, so second sources require board changes.

Aplicaciones típicas
MCP2200-I-SS es adecuado para 6 aplicacións: Adding USB to Legacy MCU Boards, Industrial Equipment Service and Commissioning Ports, Embedded Instrumentation and Data Loggers, Point-of-Sale and Payment Terminals, PC-Based Test Fixtures and Programming Adapters, IoT Gateways and Smart Home Nodes.
Adding USB to Legacy MCU Boards
The MCP2200-I/SS is purpose-built for retrofitting USB connectivity onto boards that already use a UART link. Its USB side enumerates as a virtual COM port, so existing PC terminal software and bootloaders continue to work without modification, while the UART side ties directly to MCU TX/RX pins. Because the USB termination resistors are integrated and no crystal is needed, a complete bridge typically requires only the IC, a USB connector and decoupling capacitors. The 8 GPIO can carry status LEDs or reset/boot signals, and the 256-byte EEPROM lets the board present a custom OEM USB identity.

Industrial Equipment Service and Commissioning Ports
Industrial drives, PLCs and power supplies frequently expose a UART-based service interface for commissioning and diagnostics. The MCP2200-I/SS converts that link to USB so field technicians can connect a standard laptop, with the -40C to +85C industrial temperature rating matching cabinet environments. Hardware RTS/CTS flow control protects against data loss when streaming logs, and the GPIO pins can gate the target's reset line or select firmware banks from the PC tool. The integrated EEPROM allows each product line to carry a distinct USB identity, simplifying driver whitelisting in factory IT environments.
Recomendado
Embedded Instrumentation and Data Loggers
Data loggers and bench instruments benefit from the MCP2200's full-speed USB 2.0 link streaming measurement data to a PC over the virtual COM port. The buffered UART tolerates bursty MCU-side sampling while USB transfers proceed, and RTS/CTS flow control prevents overrun during long acquisition runs. The 8 GPIO pins handle auxiliary functions such as shutter, range-select or calibration relay control directly from the host application. Because the device appears as a standard serial port, cross-platform logging software on Windows, Linux and macOS operates without custom drivers beyond the initial virtual COM port installation.
Recomendado
Point-of-Sale and Payment Terminals
POS terminals, receipt printers and card readers commonly bridge a USB host to a UART-based print or reader engine. The MCP2200-I/SS provides that bridge while its GPIO outputs drive peripherals such as cutter, paper-out sensing indicator lines or a buzzer, controlled through the vendor API. The 256-byte EEPROM supports custom VID/PID so the terminal enumerates under the OEM's brand, an often-mandatory requirement in retail certification. The 20-SSOP body fits compact handheld enclosures, and bus-powered operation from the USB 5V rail simplifies power-tree design in accessories without local supplies.
Recomendado
PC-Based Test Fixtures and Programming Adapters
Production programming adapters and test fixtures use the MCP2200-I/SS to bridge fixture control software on a PC to the UART of the device under test. The 8 GPIO are valuable here: they can switch relays, assert target reset, select socket multiplexers or light pass/fail indicators, all driven from the host over the same USB link. Flow control keeps handshake lines deterministic during firmware flashing. The industrial temperature rating and SSOP package survive repeated thermal cycling in reflow-adjacent test areas, and the low unit cost makes it practical to duplicate the bridge circuit across multi-site fixture fleets.
Recomendado
IoT Gateways and Smart Home Nodes
IoT gateway boards use the MCP2200-I/SS as a debug and provisioning console, mapping the gateway MCU's UART console to USB so field and factory tools can reconfigure nodes over a laptop connection. GPIO pins can supervise a module's boot-mode strap or power-enable line, letting the host recover a bricked node without manual intervention. The virtual COM port approach means standard terminal and scripting tools work on any OS, and the EEPROM-defined USB identity lets the gateway enumerate with a manufacturer-specific name in device managers. The CMOS part's bus-powered operation suits always-on smart home hubs where standby power matters.

Notas de diseño
The MCP2200 integrates the USB D+/D- termination resistors, so do not add external 1.5k pull-up or 22-ohm series resistors on the USB lines - duplicating termination is a common layout error that degrades eye compliance. Route D+/D- as a matched pair with length matching within a few millimeters, keep them away from switching-regulator nodes, and place the 100nF VDD decoupling capacitor within 2 mm of the supply pin with a solid ground return.
Budget the USB bus power according to the values programmed into the 256-byte EEPROM, since the descriptors declare how much current the device may draw. If the MCP2200 powers external circuitry or drives GPIO loads, verify the total stays within the declared budget or the host may disable the port. For self-powered designs, configure the EEPROM accordingly so the host does not allocate bus current unnecessarily.
Confirm the UART baud-rate accuracy requirement of your MCU against the MCP2200's internal-oscillator-derived timing before committing to high data rates; USB-referenced timing is accurate, but verify the specific rate in the datasheet rather than assuming the FT232-class range. Also plan for the fact that no other vendor offers a pin-compatible 20-SSOP part - single-source risk is real, so qualify the MCP2200-I/SO or -MQ footprints early if dual-footprint optionality is desired.
