WF200SCR

Overview

The WF200SCR is a Wi-Fi transceiver IC from the WF200 series, 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 Mb/s with DSSS modulation. The device operates on a supply voltage range of 1.8 V to 3.6 V, consuming 42.5 mA during reception and 148 mA during transmission. It delivers an output power of 17 dBm and achieves a sensitivity of -96.5 dBm. Interfaces include SPI and SDIO. The component is housed in a 32-UFQFN package with an exposed pad and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates an 802.11 b/g/n Wi-Fi radio with a secure link host interface for robust connectivity.
• Supports dual serial communication protocols including SPI and SDIO for flexible system integration.
• Designed for high reliability with extended industrial operating temperature capabilities.

Applications

• Industrial IoT sensor nodes requiring reliable wireless connectivity
• Smart home devices utilizing 802.11 b/g/n standards
• Embedded systems needing secure host interfaces

Procurement Notes

Verify the lifecycle status carefully, as this component is marked NRND (Not Recommended for New Designs). Confirm that existing designs can sustain long-term supply or plan for migration strategies. Ensure compatibility with the specified 32-QFN package dimensions and thermal requirements during procurement validation.

Selection Notes

Select this part for applications requiring integrated Wi-Fi connectivity with SPI/SDIO interfaces. Consider the 1.8V to 3.6V supply range and current consumption profiles for power budgeting. Verify that the 72.2 Mb/s data rate meets throughput requirements and that the -96.5 dBm sensitivity aligns with coverage needs.

Part Context

The WF200SCR belongs to the WF200 family of Wi-Fi transceivers by Silicon Labs. This series provides compact solutions for embedded wireless applications. The SCR suffix typically denotes specific tape-and-reel packaging configurations within the product line, distinguishing it from other variant packages.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on pin compatibility and functional equivalence rather than direct substitution lists.
