MCP2200-E/SS Обзор
A USB-to-UART bridge IC (also called a USB serial protocol converter) is a category of interface IC that translates USB signaling on the upstream port to a generic asynchronous serial (UART) interface on the downstream side. This role sits inside the broader taxonomy of interface ICs -> communication controllers -> bus bridges -> USB bridges. Bridges like the MCP2200-E are commonly used to add a USB device port to legacy designs that only expose UART, or to provide a virtual COM port for debugging, provisioning, and field firmware updates without rewriting host-side software.
Key features include a factory default of 8 GPIO pins configurable as inputs or outputs through HID-class control transfers, 256 bytes of integrated user EEPROM accessible over USB, an internal 3.3V LDO that supplies the USB transceiver from a single external 5V (VBUS) source, support for bus-powered or self-powered operation, and full compliance with USB 2.0 full-speed (12 Mbps). The IC integrates a 48 MHz internal oscillator, pull-up resistor on D+, and the 1.5 kΩ USB termination, simplifying board design to a handful of decoupling caps.
Architecturally, the MCP2200-E contains a fixed-function USB 2.0 SIE and a dedicated UART engine, with on-chip RAM buffering transmit and receive FIFOs. The chip implements a vendor HID interface for GPIO and EEPROM access and enumerates as a serial communication class (CDC) device, so no host driver is required on Windows, macOS, or Linux for the CDC portion. Flow control is supported via hardware CTS/RTS pins and an XON/XOFF software mode, and the device presents a standard baud-rate generator from 300 baud up to 1 Mbaud with custom divisors.
Typical applications include adding USB connectivity to legacy RS-232 designs, USB-to-UART cables and dongles, debug consoles for embedded MCUs, industrial sensors and instrumentation exposed to a host PC, and embedded products requiring field-update over USB. Developers also use the GPIO bank for tasks like driving status LEDs, reading push buttons, or multiplexing SPI/I2C peripherals through bit-banging.
When designing with the MCP2200-E, ensure VBUS bulk capacitance stays at or below 10 µF to meet USB 2.0 inrush-current requirements (per Section 7.2.4 of the USB specification). For self-powered designs, an intentional 1 MΩ pull-down resistor on VBUS and a 10 µF bulk cap are typically recommended for proper line-state detection during attach. Decouple VDD with 1 µF and 0.1 µF ceramics placed close to the SSOP pins.

USB to UART Bridge for MCU Debug Console
The MCP2200-E/SS provides a CDC-compliant virtual COM port to an embedded MCU that only exposes a UART, eliminating the need for an external serial chip or an FTDI-style driver install. Its 8 GPIO pins can be repurposed at run-time to drive status LEDs, sense push-buttons, or arbitrate the boot mode of the target MCU, while the 256-byte EEPROM holds board revision strings and serial numbers for field support. Because the chip is bus-powered directly from VBUS, the only required components are decoupling caps and a USB-B or Micro-B receptacle — a typical 5-wire debug port fits on less than 100 mm² of board area. Compared to software-CDC on the MCU itself, the MCP2200-E offloads USB protocol handling and presents standard COM-port IOCTLs that work with any terminal, scope, or Python pyserial client without firmware changes.

Industrial Sensor to USB Data Acquisition
In factory automation and process control, the MCP2200-E/SS bridges a sensor UART (RS-232 levels with external transceiver) to a host PC for logging, calibration, and HMIs. The -40 C to +85 C industrial temperature range supports cabinet and outdoor-enclosure deployments, while the integrated 5V-to-3.3V LDO ensures the USB transceiver draws from VBUS without a regulator. The GPIO bank can address end-of-line switches, route analog mux channels, or trigger a digital isolator, turning the bridge into a half-duplex SCADA front-end. With 256 bytes of EEPROM on-chip, calibration coefficients and node IDs can be stored directly on the bridge, simplifying provisioning when a sensor is swapped during maintenance.

USB Dongle or Cable Replacement
The MCP2200-E/SS is the silicon foundation of countless USB-to-serial dongles and replacement cables where small BOM, low cost, and zero-driver install are paramount. With internal oscillator, integrated USB termination, and integrated 3.3V LDO, the BOM collapses to one decoupling cap pair plus the USB connector — easy to fit inside a Type-A plug. The HID-class GPIO can drive activity LEDs to confirm enumeration, while the 256-byte EEPROM stores product strings used by the host. CDC enumeration means these cables look like a standard COM port in Tera Term, PuTTY, or any serial terminal without driver files; Field-Update over USB is therefore just a UART bootloader behind the bridge.

Legacy RS-232 to USB Migration
Designers upgrading legacy equipment that exposes a 5V UART into modern USB hosts can drop the MCP2200-E/SS directly onto the existing UART lines without rewriting firmware. The chip handles all USB enumeration as a CDC device, presenting a virtual COM port that re-uses existing Windows-legacy serial software. Adding a small MAX3232 or MAX232 level shifter lets the bridge mate directly with true RS-232 ±12V lines from older instruments. The 8 GPIOs are useful as handshake lines or to bring legacy control signals (DTR, RI) into the new design without extra glue logic.

IoT Gateway USB Provisioning Port
Wi-Fi and Bluetooth IoT gateways often need a USB-C port for factory provisioning, BLE firmware updates, and field diagnostics, and the MCP2200-E/SS is a drop-in choice. The CDC interface gives production-line test scripts a stable COM port, while GPIO pins can reset the wireless module, select boot mode, or feed an LED indicator. The -40 C to +85 C temperature grade and integrated ESD-tolerant 3.3V LDO make it ideal for enclosures mounted outdoors or in industrial cabinets. The 256-byte user EEPROM holds the device's serial number and hardware revision for asset tracking.

Medical and Laboratory Instrument Debug Interface
Laboratory instruments and bench-top analysers benefit from a USB service-port that does not require installing custom drivers, and the CDC-class MCP2200-E/SS enumerates as a virtual COM port on every major OS. The 8 GPIOs can drive front-panel LEDs, read keypad inputs, or assert test-mode lines during calibration in the factory. The 256-byte EEPROM can store calibration date stamps and technician IDs without an extra serial EEPROM on the BOM. Combined with the industrial temperature grade and the integrated 5V-to-3.3V LDO, this bridge simplifies BOM and accelerates IEC 62304 / FDA 21 CFR Part 11 traceability workflows.

Заметки по проектированию
VBUS bulk capacitance must not exceed 10 µF to meet USB 2.0 inrush-current requirements (Section 7.2.4). Use a 10 µF ceramic or low-ESR electrolytic on VBUS plus a 0.1 µF ceramic decoupling cap close to the VBUS pin. Decouple VDD with a 1 µF and 0.1 µF capacitor pair, and do not draw current from the internal VUSB3V3 node except for its decoupling cap (it's a decoupling node, not a 3.3 V output).
Route the USB D+/D- pair as a 90-Ω differential microstrip with matched length, and place the ESD protection array (such as USBLC6-2SC6) within 10 mm of the USB connector. Place the decoupling caps for VBUS, VDD, and VUSB3V3 on the same layer within 3 mm of their respective pins; keep the GP and UART traces on inner layers if RFI is a concern. Avoid running digital traces parallel to D+/D- for more than 5 mm.
The MCP2200E enumerates as CDC and provides a virtual COM port without a driver, but GPIO/EEPROM access requires the Microchip MCP2200 Configuration Tool or DLL — design host-side software accordingly. Tie RST to VDD through a 10 kΩ resistor (or directly for always-on), and remember that the CP2102N, FT232RL, and MCP2200 each enumerate differently: the first with SiLabs' VCP driver, the second with FTDI's D2XX or VCP, and the third with the in-box CDC. Mixing chips across PC manufacturers can confuse test operators; document the COM enumeration on the silkscreen.
