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.

DA14531
Can anyone help with the delay function for the DA14531, For example, let's say you want to turn ON an LED for 1 second and OFF for 1 Second. This might be very easy for everybody here but unfortunately, I am new to dialog Chip. thanks,
