Overview
Description
SmartBond TINY™, the world’s smallest and lowest power Bluetooth® 5.1 System-on-Chip (SoC), brings down the cost of adding Bluetooth Low Energy (LE) in any system and 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 six tiny external passives, a crystal, and a power source. To lower the barrier of entry, SmartBond TINY is also 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, SmartBond TINY is extremely power efficient, delivering a record score of 18300 on the latest EEMBC benchmark for IoT connectivity, IoTMark™.
The DA14531-01 variant of the DA14531 is optimized for peripheral-only applications and provides around 25% additional user RAM memory for a typical Bluetooth LE application compared to the DA14531-00 and is pin-to-pin compatible.
The DA14530 is pin-to-pin compatible with the DA14531 in a 2.2mm x 3.0mm FCGQFN24 package and provides cost savings by operating from an internal LDO, eliminating the cost of a DC/DC inductor.
Available in a tiny 2.0mm x 1.7mm package, the DA14531 is half the size of its predecessor or any offering from other leading manufacturers. And, it is complemented by a flexible software development kit (SDK) supporting major compilers such as Keil and GCC out of the box.
