General Description
BDE-WF3135 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-WF3135 solution provides a robust and simple security experience. The BDE-WF3135 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-WF3135 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
• 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.
