The DA1470x is a BLE 5.2 SoC combining an Arm Cortex M33 processor along with a 2D GPU, PMU, Crypto Engine, voice detector and a 240 dMIPS FPU. Renesas also offers a Pro Development Kit giving access to all the GPIOs from the DA1470x and daughterboards with additional peripherals.

The DA1470X SoC consists of an Arm Cortex-M33 as application processor and a M0+ as sensor node controller. The Cortex-M33 it’s enabled to execute code from an external Octa/Quad-SPI Flash device. However, the Quad-SPI Flash is populated.

The Pro Dev Kit comes with three compatible daughterboards which integrate a TFT LCD, a Power Measurement module (PMM2) and the Pro daughterboard which features the DA1470x SoC.

The PMM2 allows the device to monitor the critical current and voltages of the system. Additionally, it can also measure the USB and battery charging current. As seen below, the PMM2 connects to the Pro motherboard via M.2 socket. 

Renesas expects to target portable applications such as medical devices, smart appliances, security systems, etc. The video below demonstrates some of the DA170x Pro Kit features.
