In today’s crowded wireless landscape, reliable connectivity isn’t just a feature，it’s a fundamental requirement for successful product design. For engineers and OEMs developing solutions for IoT, 産業用自動化, スマートな小売アプリケーション, the Realtek W-iFi Module FSC-BW236 delivers a powerful, pre-certified wireless solution built around the proven RTL8720DN SoC. This compact module combines advanced dual-band Wi-Fi with Bluetooth® 5.0 in a complete system-ready package that accelerates development while ensuring reliable performance.

 

Engineered for Real-World パフォーマンス

The FSC-BW236’s dual-band Wi-Fi capability (2.4 ghzと 5 GHz) with full 802.11 a/b/g/n compliance addresses the growing challenge of RF interference in connected environments. In practical terms, this means a wireless payment terminal in a busy retail store can maintain stable transactions on the less-congested 5 GHzバンド.

 

The integrated Bluetooth 5.0 functionality extends design possibilities beyond simple Wi-Fi connectivity. Engineers can implement BLE for device provisioning，allowing end-users to easily configure Wi-Fi settings through smartphone apps. This dual-radio approach provides the flexibility needed for modern connected products.

 

Beyond Basic Connectivity: A Complete Embedded Platform

What truly distinguishes the FSC-BW236 is its integrated dual-core architecture, featuring an ARM Cortex-M4F for application processing and a Cortex-M0 for power management. This enables developers to run custom firmware directly on the module, processing sensor data and managing device logic without requiring an external microcontroller. For battery-powered devices, this integration means smarter power management—the module can handle complex tasks during active periods while dropping to deep sleep currents as low as 10 µA during idle states.

 

The module’s comprehensive peripheral set includes UART, I2C, spi, PWM, and USB interfaces, supporting diverse applications from environmental sensor networks to motor control systems. Each interface is designed with real-world implementation in mind, featuring configurable pull-up resistors and drive strength settings that simplify board design.

 

Deployment-Ready for Demanding Environments

The FSC-BW236 demonstrates its engineering maturity through robust environmental specifications. The industrial-temperature variant (FSC-BW236C) operates from -40°C to +105°C, making it suitable for applications ranging from solar inverters in desert installations to outdoor monitoring equipment in cold climates. This thermal resilience ensures consistent performance where lesser modules would fail.

 

Multiple antenna options including onboard, IPEX connector, and stamp-hole designs，provide mechanical flexibility for different enclosure types and RF requirements. 開発者向け, this means the ability to optimize antenna performance for specific installation scenarios without redesigning the core module.

 

The module’s comprehensive certification portfolio covers FCC, IC, ce, KC, テレック, and SRRC requirements, significantly reducing the time and cost associated with regulatory compliance. This pre-certification is particularly valuable for startups and enterprises alike, accelerating time-to-market while ensuring global market access.
