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
