Renesas / Dialog DA14581 Low Power BLUETOOTH Smart SoC

Renesas / Dialog DA14581 Low Power BLUETOOTH® Smart SoC is a small, low power, and integrated BLUETOOTH® Smart solution for A4WP wireless charging and HCI applications. It is an optimized version of the outstanding DA14580 SoC. Fast boot time for the Power Receiving Unit (PRU) and 8 connections for the Power Transmitting Unit (PTU) make the DA14581 a perfect solution for A4WP. The optimized code for HCI, which fits into the DA14581's OTP memory, enables you to create a pre-programmed HCI device. It has a fully integrated radio transceiver and a baseband processor for Bluetooth Smart. It can be used as a standalone application processor or as a data pump in hosted systems.
