  • BDE-WF3135N(WiFi Dual-Band Network Processor Module Based on CC3135)


    BDE-WF3135N dramatically simplifies the implementation of Internet connectivity. This dual-band Wi-Fi® network processor module can be added to any low-cost, low-power microcontroller unit (MCU); it integrates all protocols for Wi-Fi® and Internet, which greatly minimize host MCU software requirements.


    This ROM-based subsystem includes an 802.11 a/b/g/n dual-band 2.4 GHz and 5 GHz radio, baseband, and MAC with powerful hardware cryptographic engine. With built-in security protocols, the BDE-WF3135N solution provides a robust and simple security experience. The BDE-WF3135N is available in an LGA package that is easy to lay out with all required components including serial Flash, RF filters, diplexer, crystal, and passive components that are fully integrated.


    This generation introduces new capabilities that further simplify the connectivity of things to the Internet. The main new features of BDE-WF3135N include:


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

           2.4 GHz Coexistence with Bluetooth® low energy radio

           Antenna diversity
