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
