As the wireless chip vendors race to carve out a position in the internet of things (IoT), they know security breakthroughs will be important to gain an advantage over rivals. ARM and Intel are battling to enhance chip-level security in their designs for embedded, ultra-low power devices. Broadcom has also made security the centrepiece of its latest offering for the IoT. The new system-on-chip (SoC), the BCM20737, is part of Broadcom’s WICED (Wireless Internet Connectivity for Embedded Devices – pronounced Wicked) family. The first modules in this range were unveiled in late 2011 but it is now being expanded into a platform with a surrounding ecosystem of simple applications in areas like intelligent lighting control, an approach also taken by…
