WF200CR

Overview

The WF200CR is a Wi-Fi transceiver IC from Silicon Labs supporting 802.11 b/g/n standards in the 2.4 GHz band (2.412–2.484 GHz). It features a maximum data rate of 72.2 Mbps with DSSS modulation and an output power of 16 dBm. The device operates on a supply voltage range of 1.8 V to 3.3 V, with receive current at 42.5 mA and transmit current at 148 mA. It includes SPI and SDIO interfaces and functions within a temperature range of -40°C to +105°C.

Feature Summary

Supports 802.11 b/g/n Wi-Fi protocols for reliable wireless connectivity
Optimized for low-power IoT applications with reduced transmit and receive currents
Integrates hardware encryption accelerators for AES, PKE, and TRNG security functions
Provides excellent link budget and antenna diversity for crowded 2.4 GHz environments

Applications

IP security cameras
Point-of-sale (PoS) terminals
Consumer health care devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the part number matches the exact suffix 'CR' to ensure correct package and temperature grade specifications. Check for end-of-life status as the product lifecycle is marked as NRND. Request official datasheets and test reports to validate performance parameters against application requirements before finalizing procurement orders.

Selection Notes

Select this component for battery-powered IoT designs requiring certified Wi-Fi connectivity without complex RF engineering. The integrated nature reduces development time compared to discrete solutions. Ensure host systems support required SPI/SDIO interfaces and provide adequate thermal management for the QFN32 package. Consider the pre-certified status to minimize regulatory testing efforts for FCC, CE, and other regional compliance requirements.

Part Context

The WF200CR belongs to Silicon Labs' IoT Wi-Fi product family, designed alongside the WFM200 module. It targets space-constrained and power-sensitive applications where high reliability and security are paramount. This transceiver complements the company's broader Wireless Gecko SoC portfolio, offering a dedicated radio solution for developers needing flexible integration with external antennas.
