DesignWare Bluetooth Low Energy Link Layer IP

Compliant with Bluetooth 5, Synopsys’ DesignWare® Bluetooth® Low Energy Link Layer IP delivers wireless connectivity for Internet of Things (IoT) System-on-Chips (SoCs). The Link Layer IP incorporates advanced data encryption and random number generation for secure wireless connections, allows up to eight simultaneous connections in a single instantiation, and 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. With the complete DesignWare Bluetooth Low Energy IP solution consisting of Link Layer and PHY IP, years of analog and RF design experience and a broad portfolio of silicon-proven IP shipping in volume, Synopsys provides a robust wireless IP solution ready for integration into advanced SoC designs.
