WF200C

Overview

The WF200C is a Wi-Fi network co-processor integrating an 802.11 b/g/n radio with baseband, MAC, and security functions. It operates within the 2.412 GHz to 2.484 GHz frequency range and supports a maximum data rate of 72.2 Mb/s using DSSS modulation. The device requires a supply voltage between 1.8 V and 3.6 V, drawing 42.5 mA during reception and 148 mA during transmission. It delivers an output power of 17 dBm and features an SPI interface. The component is rated for operation from -40°C to +105°C.

Feature Summary

Integrates RF, baseband, MAC, and security functions into a single chip
Includes integrated LNA, PA, and balun for enhanced link budget
Features built-in OTP memory eliminating the need for external EEPROM

Applications

IoT sensor nodes requiring secure Wi-Fi connectivity
Smart home appliances with embedded networking
Industrial monitoring systems operating in extreme temperatures

Procurement Notes

Verify current availability status as the component is marked NRND (Not Recommended for New Designs). Confirm that the specific package variant matches your PCB footprint requirements. Ensure firmware compatibility with the secured binary files provided by Silicon Labs. Check for alternative lead times due to potential end-of-life constraints.

Selection Notes

Select this component when a dedicated Wi-Fi NCP with integrated power amplification is required. The integrated LNA and PA simplify RF front-end design compared to discrete solutions. Consider the wide operating temperature range for harsh environments. Verify SPI interface compatibility with the host microcontroller.

Part Context

The WF200C belongs to the WFx family of Wi-Fi transceivers from Silicon Labs. It serves as a network co-processor, offloading Wi-Fi tasks from the main application processor. This architecture reduces system complexity and power consumption while maintaining robust wireless connectivity standards.
