  • WiFi Dual-Band MCU Module

    BDE-WFM20B (Part# BDE-WFM20BS or BDE-WFM20BSF) is a 802.11a/b/g/n, 2.4GHz and 5GHz Dual-Band, IPv4 & IPv6, 256KB of RAM (or 1MB of executable flash/256KB of RAM) Low Energy MCU module based on CC3235S(or CC3235SF) SoC. The module offers a unique combination of lower power, integration of all external components including Dual-band chip antenna at a very affordable cost.


    Created for IoT, the BDE-WFM20B module is a wireless module that integrates two physically separated on-chip MCUs, a CM4 application processor and a network processor.


    BDE-WFM20B introduces new capabilities that further simplify the connectivity of things to the Internet. The main features of BDE-WFM20B include:

               802.11 a/b/g/n: 2.4 GHz and 5 GHz support

               2.4 GHz Coexistence with Bluetooth® low energy radio

               Integrated Dual-band chip antenna or UFL connector for external antenna

               More concurrent secure sockets, up to 16

               Unique device identifier with ability to generate certificate signing request (CSR)

               Online certificate status protocol (OCSP)

               Wi-Fi Alliance® certified for IoT low power capabilities

               Hostless mode for offloading template packet transmissions

               Improved fast scan.

               Application processor— Arm® Cortex®-M4 MCU with a user-dedicated 256KB of RAM and an optional 1MB

    of executable flash.

               Network processor to run all Wi-Fi and Internet logical layers. This ROM-based subsystem completely

    offloads the host MCU and includes an 802.11 a/b/g/n dual-band 2.4-GHz and 5-GHz radio, baseband, and

    MAC with a powerful hardware cryptography engine.

               32Mbit SPI serial flash
