Overview
Description
The SmartBond™ DA1469x family of Bluetooth® Low Energy solutions features advanced multi-core microcontroller units designed for robust wireless connectivity. Building on the success of Renesas' SmartBond line, these units include three additional cores, enhancing processing power, resources, range, and battery life. This expanded capability supports a variety of consumer applications, including high-end fitness trackers, sophisticated smart home devices, and immersive virtual reality game controllers.
Powered by the Arm® Cortex®-M33 processor, the DA1469x products deliver superior processing performance, catering to demanding applications. They also support the latest Bluetooth Low Energy 5.2 protocol and proprietary 2.4GHz deployment, facilitating precise Real-Time Locating Systems (RTLS) and low-latency communications. The inclusion of a Sensor Node Controller (SNC) allows for autonomous sensor data processing, further enhancing device functionality.
The DA1469x family is equipped with a state-of-the-art Power Management Unit that optimizes energy efficiency by selectively activating processing cores only when needed. This integration eliminates the requirement for a separate PMIC, thereby reducing system size and enhancing overall performance.
