Bluetooth chip that combines a radio transceiver, an Arm^® M0+ microcontroller, memory, peripherals and security features in a compact SoC design. The DA14533, the first automotive-qualified device in the company’s Bluetooth^® Low Energy system-on-chip (SoC) family, includes advanced power management features to simplify system integration and reduce power consumption. With its software stack qualified against Bluetooth Core 5.3 and support for extended temperatures, developers can jump-start projects in applications from tire pressure monitoring and keyless entry to wireless sensors and battery management systems.
DA14533 includes some of the most advanced power management features in the industry. The device includes an integrated DC-DC buck converter, which accurately adjusts the output voltage according to system requirements. Active system power consumption is lower than comparable devices in the market, requiring only 3.1mA during transmission and 2.5mA during reception. In hibernation mode, the current drops to 500nA. These power management and power-saving features help extend the operational life of small-capacity battery-powered systems and meet the stringent power requirements of tire pressure monitoring systems’ mission profile.
The DA14533 is an AEC-Q100 Grade 2 qualified device, which means the device has passed strict testing to sustain quality and reliability in harsh automotive environments.
