Bluetooth Controller Synopsys’ DesignWare® Controller IP for Bluetooth low energy, Thread, and Zigbee delivers secure, concurrent wireless connectivity for Internet of Things (IoT) applications such as wearables, industrial, smart homes, and smart cities. The controller incorporates advanced data encryption and random number generation for secure wireless connections, and allows multiple simultaneous connections between supported protocols in a single instantiation. It also provides validated interoperability with software stacks through a physical or a virtual Host Controller Interface (HCI). The IP is delivered as RTL and firmware corresponding to an optimized IP partition to minimize system power dissipation and allow for functionality upgrades through software updates. The firmware runs on an external processor that can either be a dedicated processor or host processor. The controller is thoroughly tested and qualified in accordance with the Bluetooth Special Interest Gr
