The DA1469x family offers advanced connectivity, allowing developers to prove their equipment and meet the needs of multiple applications in the future.

Dialog Semiconductor has introduced a range of Bluetooth low energy SoCs in the embedded world with the SmartBond DA1469x family. It is a first-line wireless microcontroller based on the ARM Cortex M33.



The new product line DA1469x's Dialog Semiconductor has a core that has been carefully tested according to its capabilities, selecting processes between network devices and communicating three processors.

The DA1469x home-based application processor ARM M33 for power calculation. It provides developers with more powerful application processing capabilities, such as high-end fitness trackers, advanced smart home devices and virtual reality game controllers.

The new dual-range integrated radio transceiver is based on the ARM Cortex-M0+ with a software-programmable packet engine on which the protocol is implemented. With the new Bluetooth 5.1 standard, the transceiver can be precisely positioned with the newly introduced 5.1 angle and exit angle functions. They make it possible to accurately determine the location of the internal equipment, for example to implement functions for building access and remote keyless entry systems.


Processor and sensor controller

The DA1469x improves SoCs, then the M33 application processor and the M0+ Protocol Engine (SNC) are added by the sensor node controller, which is based on the programmable micro DSP. It can autonomously process the data of sensors connected to its digital and analog interfaces independently and wake up the application processor only when needed. In addition to this power-saving feature, the internal power supply provides advanced power management by controlling the various cores and enabling them when needed. The internal power supply has three regulated outputs for the internal block and LDO output to supply external components, so that no separate voltage regulator integrated circuit is required.


The SOC DA1469x family features up to 144 DMIPS (Dhrystone MIPS), 512 kB of RAM, storage protection, floating point units, end-to-end security and a dedicated encryption engine in scalable memory to ensure a variety of advanced smart devices Applications can be implemented through the chipset family. In addition, they are equipped with some key interfaces, including a display driver, audio interface, USB, an accurate ADC, a driver for the vibration motor, two ERM (eccentric rotation mass) and LRA (linear vibration motor), and A programmable stepper motor controller.


The four variants of the new DA1469x product line build the dialogue's success in smart bond products and provide more computing power, resources, range and battery life for a variety of IoT-related consumer applications. Using the series to develop DA1469x work can rely on the dialogue software development kit SmartSnippets, let their tools in hand, they need to develop new SoC applications.
