Overview

The CP2110-F01-GM is a highly integrated USB-to-UART Bridge Controller that implements the HID (Human Interface Device) class, eliminating the need for custom driver installation on most operating systems. It features an on-chip voltage regulator, an internal oscillator, and 343 bytes of one-time programmable ROM in a compact 4x4 mm QFN24 package. The device supports full-speed USB 2.0 and offers a UART interface with data rates from 300 bps to 1 Mbps.

Why Choose This Part

This controller reduces BOM cost and PCB space by integrating the USB transceiver, clock, and voltage regulator into a single IC. It supports advanced features like 10 GPIO pins, USB suspend states, and line break transmission for versatile system integration. Engineering effort is further reduced because the HID interface allows for plug-and-play operation without the complexities of VCP driver certification.

Applications

Driverless USB Connectivity
Utilizes the standard USB HID class supported natively by Windows, macOS, and Linux to avoid third-party driver distribution issues.
Industrial RS-485 Bridging
Features a dedicated RS-485 mode with hardware-based bus transceiver control for robust half-duplex communication.
Handheld Diagnostic Tools
Ideal for portable equipment due to its small 4x4 mm footprint and low 11.3mA typical operating current.
Legacy System Upgrades
Simplifies the process of adding USB connectivity to existing MCU-based designs via a standard UART interface with hardware flow control.

Getting Started

To begin development, engineers can use the CP2110EK Evaluation Kit which provides a complete prototyping platform. Silicon Labs provides a HID-to-UART DLL and API for application-level development on the host side, while the 343-byte OTP ROM can be programmed with custom VID/PID and serial strings using the Xpress Configurator tool.

Also Consider

CP2102N SiLSilicon Labs - A similar footprint but uses Virtual COM Port (VCP) drivers for applications requiring standard serial port emulation rather than HID class.
