CP2102N-A02-GQFN20

Controllers Overview

The CP2102N-A02-GQFN20 is a USB-to-UART bridge controller from Silicon Labs' USBXpress family, housed in a QFN20 package. It integrates a USB 2.0 full-speed function controller, transceiver, oscillator, and UART with 512-byte receive and transmit buffers. Operating on a single supply of 3.0 V to 3.6 V, it supports baud rates up to 3 Mbaud and includes four digital I/O pins. The device operates within an ambient temperature range of -40 °C to +85 °C.

Controllers Feature Summary

• Eliminates firmware development by integrating all necessary USB components on-chip
• Configurable via a simple GUI-based configurator for customization
• Supports hardware handshaking signals including RTS, CTS, DSR, and DTR
• Includes internal voltage regulator and programmable configuration memory

Controllers Applications

• POS terminals
• USB dongles
• Gaming controllers
• Medical equipment
• Data loggers

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the target system's power supply requirements and interface standards before finalizing procurement decisions.

Controllers Selection Notes

Select this component when a compact solution is required for upgrading RS-232 designs to USB. The QFN20 package offers a small footprint suitable for space-constrained applications. Verify that the integrated GPIO count meets the design needs, as other packages in the series offer additional pins.

Controllers Part Context

This part belongs to the CP2102N series, which provides pin-compatible alternatives in QFN24 and QFN28 packages. These variants offer increased GPIO availability or battery charger detection features while maintaining the same core USB-to-UART functionality and software driver support.

Controllers Replacement Considerations

Pin-compatible replacements include the CP2102N-A02-GQFN24 and CP2102N-A02-GQFN28. Verify that any substitute maintains the required operating voltage range and thermal characteristics for the intended application environment.
