Wi-Fi speeds at Bluetooth power

Ensigma Whisper RPUs implement a patented PowerGearing low power consumption technique that includes advanced design techniques and process technology features, enabling the lowest active and idle power. Whisper RPUs extend overall system battery life while maintaining consistent connectivity and providing a rich set of features.

Whisper RPUs are available in a wide range of performance capabilities, from single-standard to multi-standard implementations. In addition, all Whisper RPUs include an integrated MIPS processor that can be scaled as required to enable support for an integrated host stack, removing the need for a separate host processor and thereby reducing both solution size and cost
