CP2105-F01-GM

Controllers Overview

The CP2105-F01-GM is a single-chip USB to dual UART bridge controller manufactured by Silicon Labs. It integrates a USB 2.0 full-speed function controller, transceiver, and oscillator within a 24-pin QFN (4x4 mm) package. The device supports self-powered operation at 3.0 V to 3.6 V or bus power at 4.0 V to 5.25 V. It features an Enhanced Communications Interface (ECI) supporting baud rates from 300 bps to 2.0 Mbps with configurable data formats, and a Standard Communications Interface (SCI) supporting up to 921600 bps. Supply current is typically 17 mA during normal operation.

Controllers Feature Summary

• Integrates USB 2.0 full-speed controller and transceiver without external components
• Provides two independent UART interfaces with distinct performance capabilities
• Includes on-chip voltage regulator and one-time programmable ROM for customization
• Supports hardware flow control and user-configurable GPIO signals

Controllers Applications

• Replacing legacy RS-232 designs in embedded systems
• Industrial automation requiring dual serial communication channels
• IoT devices needing USB connectivity with multiple serial peripherals

Controllers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type. The GM suffix denotes tube packaging, whereas the GMR suffix indicates tape-and-reel. Ensure compatibility with required I/O voltage levels and operating temperature ranges before finalizing procurement specifications.

Controllers Selection Notes

Select this component when dual UART functionality is required within a compact footprint. The ECI interface offers higher baud rate flexibility compared to the SCI interface. Consider the integrated voltage regulator and lack of external crystal requirements for simplified board design. Verify that the 24-pin QFN package dimensions align with the target PCB layout constraints.

Controllers Part Context

This part belongs to the CP2105 series of USB-to-UART bridge controllers. It is designed as a drop-in replacement for traditional RS-232 solutions, offering royalty-free driver support for Windows, Mac OS-X, and Linux platforms. The device simplifies system firmware development by appearing as standard COM ports to host applications.

Controllers Replacement Considerations

CP2105-F01-GMR serves as the functional equivalent packaged in tape-and-reel format.
