CP2102N-A01-GQFN20R

Controllers Overview

The CP2102N-A01-GQFN20R is a USB-to-UART bridge controller from the Silicon Labs USBXpress family, housed in a 20-pin QFN package measuring 3 mm x 3 mm. It integrates a USB 2.0 full-speed function controller, transceiver, oscillator, and UART with 512-byte receive and transmit buffers. The device operates on a single supply voltage of 3.0 V to 3.6 V, drawing a typical current of 9.5 mA during normal operation at 115200 baud. It supports data transfer rates up to 3 Mbaud and includes four general-purpose input/output pins.

Controllers Feature Summary

Integrates USB 2.0 full-speed controller and UART without requiring external components
Includes internal oscillator and voltage regulator for simplified design
Supports hardware and software handshaking protocols
Features programmable GPIO pins with configurable output modes

Controllers Applications

Point-of-sale terminals
USB dongles
Gaming controllers
Medical equipment
Data loggers

Controllers Procurement Notes

Verify the specific firmware revision indicated by the 'A01' suffix against project requirements, as it differs from the standard 'A02' version. Confirm that the tape and reel packaging aligns with automated assembly capabilities. Ensure compatibility with the intended host operating systems for driver support.

Controllers Selection Notes

Select this component when a compact footprint is required, as the QFN20 package is the smallest in the series. Choose this part over larger packages if only four GPIO pins are necessary. Verify that the integrated voltage regulator meets the power budget, as it limits the maximum output current compared to external solutions.

Controllers Part Context

This device belongs to the CP2102N series, which offers varying pin counts and GPIO configurations. The QFN20 variant provides the most space-efficient solution within the family. It serves as a direct replacement for legacy RS-232 designs, simplifying the transition to USB connectivity while maintaining compatibility with existing COM port applications.
