CP2105-F01-GMR USB 2.0 Dual UART Bridge | Silicon Labs
MPN: CP2105-F01-GMR ✓ فعالCP2105-F01-GMR نمای کلی
A USB-to-UART bridge is an interface IC that translates USB traffic from a host computer into serial data for UART-based embedded equipment. In the broader semiconductor hierarchy, the CP2105 belongs to interface controllers, USB interface devices, and data-conversion components used to simplify host-to-embedded serial connectivity. Its integrated clock generator, voltage regulator, power-on reset, and USB transceiver reduce the number of external support components required in a USB-to-serial design.
The CP2105 provides programmable baud-rate generation, hardware flow-control support, a 296-byte one-time programmable ROM for customizable product information, and an integrated 3.45 V regulator. The two UART channels make it suitable for dual-port debug consoles, configuration tools, industrial controllers, test equipment, and embedded systems that need more than one serial port. The USB side operates at full speed, while the serial side uses asynchronous UART signaling.
Its internal architecture combines the USB function controller, transceiver, oscillator, ROM, UART logic, and modem-control functions on one die. The integrated USB transceiver avoids the need for external USB termination resistors, and the internal clock means the design does not require a crystal oscillator. These features are particularly useful when minimizing external component count in compact embedded products.
Typical applications include firmware update and debug interfaces, programmable serial adapters, test-and-measurement equipment, industrial automation controllers, data-acquisition systems, and USB-to-UART cable designs. The dual-channel architecture allows two independent serial links to be exposed through one USB device connection, reducing host USB-port usage.
PCB design should account for short USB traces, controlled return paths, adequate decoupling near the power pins, and a ground layout that minimizes noise coupling into the UART and USB paths. The QFN-24 package is small and has limited thermal and routing margin, so pin assignment, exposed-pad grounding, and assembly requirements should be followed exactly as described in the manufacturer datasheet.
This page combines the supplied manufacturer and distributor information, verified availability data, and practical interface-design guidance. It also identifies the available drop-in alternatives without inferring specifications that are not present in the supplied source material.

کاربردهای معمول
CP2105-F01-GMR مناسب است برای 6 کاربردs: Dual Serial Debug Console, Programmable USB-to-UART Adapter, Industrial Controller Service Interface, Test and Measurement Instrument, Data-Acquisition and Sensor Gateway, Embedded Product Configuration Port.
Dual Serial Debug Console
The CP2105-F01-GMR is well suited to a dual serial debug console because its two asynchronous UART buses and full modem-control signals let one USB connection expose two independent serial channels. A host application can enumerate the two ports and use one link for runtime logging while the other handles command or firmware-debug traffic. Programmable baud rate and hardware flow-control support help match the console to target devices, while the integrated clock and USB transceiver reduce external support circuitry in compact embedded equipment.

Programmable USB-to-UART Adapter
The CP2105-F01-GMR can form the core of a programmable USB-to-UART adapter for programming, configuration, and service interfaces. Its USB 2.0 full-speed controller and two UART channels allow one adapter to serve two equipment ports, while programmable baud rates accommodate different target-device speeds. The integrated USB transceiver, oscillator, and power-on reset reduce the adapter’s external component count, although USB enumeration strings and product-specific interface descriptors must be configured for the finished product.
پیشنهادی
Industrial Controller Service Interface
The CP2105-F01-GMR fits an industrial controller service interface where technicians need a reliable USB connection to embedded equipment. Two UART channels can support a primary control channel and a secondary status or diagnostic channel, reducing the number of USB ports required on a laptop or service terminal. The device supports 1.8 V or 3.3 V operation, programmable baud rates, and hardware flow control, while its integrated clock and transceiver simplify the physical implementation. Industrial temperature and EMC requirements must be verified separately for the final system.
پیشنهادی
Test and Measurement Instrument
The CP2105-F01-GMR is useful in test and measurement instruments that need USB connectivity for firmware updates, calibration, data capture, or instrument control. A dual-UART implementation can separate a control channel from a measurement or trigger channel, while programmable baud rates accommodate different instrument subsystems. The integrated 3.45 V regulator and internal oscillator can reduce board area, but designers should preserve the datasheet’s USB routing and decoupling guidance to avoid signal-integrity problems in precision equipment.
پیشنهادی
Data-Acquisition and Sensor Gateway
The CP2105-F01-GMR can connect a sensor gateway or data-acquisition controller to a USB host. One UART channel may receive sensor updates while the second handles configuration commands, status reporting, or external equipment control. Its programmable baud rates and hardware flow control support communication with embedded sensors and controllers, and the integrated USB transceiver reduces the need for a separate USB interface IC. Firmware must implement the appropriate UART framing and USB class or vendor-specific protocol for the gateway application.
پیشنهادی
Embedded Product Configuration Port
The CP2105-F01-GMR is appropriate for an embedded product configuration port that needs USB service connectivity without consuming several host ports. Two UART channels can support a production configuration interface alongside a persistent diagnostic channel, while programmable baud rates and modem-control signals improve interoperability with external equipment. The compact QFN-24 package is useful in space-constrained products, but exposed-pad grounding, USB trace geometry, connector protection, and host-driver behavior must be validated in the final mechanical and firmware design.

تفاوت‌های کلیدی

- Product customization and dual-port functionality (در مقابلXR21V1412IL32-F)
یادداشت‌های طراحی
Route USB D+ and D- as a short, tightly coupled pair with a continuous return path and minimal stubs. Place the USB connector protection and series-resistor network close to the connector, and follow the manufacturer’s recommended QFN-24 footprint and exposed-pad grounding pattern. Because the CP2105 integrates the USB transceiver, external termination resistors are not required according to the supplied source descriptions, but connector, ESD, and layout choices still determine practical signal integrity.
Place decoupling capacitors near the supply and ground pins using the manufacturer’s recommended values and placement. The device supports 1.8 V or 3.3 V operation and includes an internal 3.45 V regulator, but the exact external supply, regulator bypass, and exposed-pad connections must be confirmed in the datasheet. Do not assume that the integrated regulator eliminates all external power filtering or that the QFN thermal pad can be left unconnected.
Do not treat every USB-to-UART converter as a drop-in replacement. The CP2105 provides two UART channels, and the supplied cross-reference search explicitly describes XR21V1412IL32-F as a functional alternative that is not pin compatible. Before replacing the CP2105-F01-GMR, verify the package, pin mapping, USB descriptors, clock requirements, UART channel count, flow-control signals, driver behavior, and production programming requirements.
