  • WF3135A

    WF3135A is a 802.11a/b/g/n, 2.4GHz and 5GHz Dual-Band, IPv4 & IPv6 network processor module based on CC3135

    With all Wi-Fi® and Internet protocols integrated in this module which greatly minimize host MCU software requirements, it can be added to any low-cost, low-power microcontroller unit (MCU).

    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-WF3135A solution provides a robust and simple security experience. The BDE-WF3135A 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.

    BDE-WF3135A introduces new capabilities that further simplify the connectivity of things to the Internet. The main features of BDE-WF3135A 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

    •      32 Mbit SPI Serial Flash.
