CP2102N-A01-GQFN24

Controllers Overview

The CP2102N-A01-GQFN24 is a USB-to-UART bridge controller from the Silicon Labs USBXpress family. It integrates a USB 2.0 full-speed function controller, transceiver, oscillator, and UART within a 24-pin QFN package measuring 4x4 mm. The device supports data transfer rates up to 3 Mbaud and operates on a single power supply ranging from 3.0 V to 3.6 V. It includes four general-purpose input/output pins and features an internal voltage regulator providing a 3.3 V output. The component requires no external USB components or firmware development for basic operation.

Controllers Feature Summary

• Eliminates complex firmware and driver development through integrated USB functionality
• Includes a simple GUI-based configurator for customization and configuration options
• Integrates USB transceiver and clock without requiring external resistors or crystals
• Supports USB Battery Charger Detection compliant with the USB BCS 1.2 specification

Controllers Applications

• Point of Sale (POS) terminals
• USB dongles
• Gaming controllers
• Medical equipment
• Data loggers

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product selection guide to confirm pinout compatibility and feature availability. Ensure the selected package variant matches the required PCB land pattern and thermal dissipation needs for the target application environment.

Controllers Selection Notes

Select this model when four GPIO pins are sufficient for system control and battery charger detection is not required. Verify that the 4x4 mm QFN24 footprint aligns with the available board space constraints. Confirm that the operating voltage range meets the design requirements for both the host interface and the connected serial peripheral.

Controllers Part Context

This component belongs to the CP2102N series, which provides highly integrated USB-to-UART bridging solutions. The series offers multiple package options including QFN20, QFN24, and QFN28 to accommodate varying pin counts and feature sets such as battery charger detection capabilities across different form factors.

Controllers Replacement Considerations

The CP2102N-A02-GQFN24 serves as a direct functional replacement for the A01 variant, differing primarily in firmware revision. Check the datasheet for any specific firmware-dependent behaviors before substituting.
