The Renesas DA14533 Bluetooth LE SoC offers power management features to reduce power consumption in automotive systems. AEC-Q100 Grade 2 qualified, it operates from -40°C to +105°C and is suitable for applications such as tire pressure monitoring, keyless entry, wireless sensors, and battery management systems.
Along with an Arm Cortex-M0+ MCU, the DA14533 combines a 2.4-GHz radio transceiver, memory, peripherals, and security functions in a 22-pin wettable-flank, fine-pitch QFN package that is just 3.5×3.5 mm. Its software stack is qualified to Bluetooth Core 5.3 and includes the latest security features, enabling developers to jumpstart their projects.
An integrated DC/DC buck controller adjusts the DA14533’s output voltage to match system requirements. Active power consumption is 3.1 mA during transmission and 2.5 mA during reception, dropping to 500 nA in hibernation mode. These features help extend the operational life of small-capacity battery-powered systems.
The DA14533 is available now, supported by the Bluetooth Low Energy SoC Development Kit Pro.
