Description:DA14708 builds off the successes of Renesas’ SmartBond™ line, with Arm Cortex®-M33F at 160 MHz as integrated application processors, 2D graphics processor, Voice Activity Detector (VAD) and Power Management Unit (PMU). With its ultra-low-power radio transceiver offering +6 dBm output power, and -97 dBm sensitivity combined with its software-configurable and upgradeable protocol engine (MAC), the DA14708 is capable of supporting Bluetooth® low energy as well as multiple other 2.4GHz protocols. These unique f
Renesas provides a recommended PCB layout guide in their application note (AN-DA14708-00000HZ2-PCB-LAYOUT-GUIDE) which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The DA14708-00000HZ2 has multiple power modes, including sleep and hibernate modes. To configure the device for low power consumption, refer to the datasheet section 7.3 'Power Management' and use the provided APIs to control the power modes. Additionally, optimize the system design to minimize power consumption during active modes.
The DA14708-00000HZ2 has an operating temperature range of -40°C to 85°C, as specified in the datasheet section 4.1 'Absolute Maximum Ratings'. However, it's essential to consider the thermal design and heat dissipation in the system to ensure reliable operation within this range.
Yes, the DA14708-00000HZ2 is suitable for battery-powered applications due to its low power consumption and sleep modes. However, it's crucial to consider the battery life requirements and design the system to optimize power consumption, taking into account the device's power modes and peripheral usage.
Renesas provides a Secure Boot and Firmware Update guide (AN-DA14708-00000HZ2-SECURE-BOOT-FW-UPDATE) that outlines the recommended implementation for secure boot and firmware updates. This includes using the device's built-in security features, such as the Secure Boot Loader and cryptographic accelerators.

Renesas DA14706 Highly Integrated Advanced Bluetooth 5.2 SoC
Video Description
Renesas’ SmartBond DA1470x family of advanced Bluetooth 5.2 SoCs enable voice-controlled sensor applications with rich graphical interfaces while maximizing battery life.
The DA1470x family of Bluetooth SoCs integrate a 160-megahertz Arm Cortex-M33F application processor, an Arm Cortex-M0+ sensor node controller for efficiently reading and processing sensor data, and an ultra-low power 2D GPU core and display controller providing advanced graphics capabilities.
These devices feature a highly efficient 2.4 gigahertz radio that provides a 103 dB link budget. This is paired with an upgradeable and software-configurable MAC that can support Bluetooth LE 5.2 and proprietary protocols.
These SoCs also have an integrated battery charger and a system power management unit that provides multiple rails to power the SoC plus external loads.
The ultra-low power Voice Activity Detector enables always-on audio processing to support keyword detection on the edge for additional power savings and improved privacy.
