SmartBond™ DA14531 – The world’s smallest and lowest power Bluetooth 5.1 System-on-Chip

The DA14531 aka SmartBond TINY™ is the Bluetooth® low energy solution to power the next 1 billion IoT devices

SmartBond TINY™, the world’s smallest and lowest power Bluetooth 5.1 System-on-Chip, brings down the cost of adding Bluetooth low energy in any system to $0.50 in high volumes. This awesome combination takes mobile connectivity to places previously out of reach, triggering a wave of a billion IoT devices, all with SmartBond TINY™ at the heart.

The low system cost is achieved through the high level of integration in SmartBond TINY™: a complete Bluetooth low energy system can be achieved with the addition of 6 tiny external passives, a crystal and power source. And to lower the barrier of entry, SmartBond TINY™ will also be available in an easy-to-use tiny module incorporating all the needed components, making the addition of Bluetooth low energy to any application a simple drop-in.

Record low hibernation and active power consumption ensure long operating and shelf life with even the tiniest, disposable batteries. Based on a powerful 32-bit arm Cortex M0+ with integrated memories and a complete set of analog and digital peripherals, SmartBondTINY™ is extremely power efficient, delivering a record score of 18300 on the latest EEMBC benchmark for IoT connectivity, IoTMarkTM.

Available in a tiny 2.0 x 1.7 mm package, the DA14531 is half the size of its predecessor, or any offering from other leading manufacturers. And it is complemented by a flexible SDK supporting major compilers such as Keil and GCC out of the box.
