Tiny Bluetooth SoC For Powering New Generation Of IoT Devices


World’s smallest power-efficient chip with long battery equips the upcoming IoT devices to give excellent performance

With an increase in IoT devices requiring wireless connectivity, the increased development cost poses a challenge in their deployment as well in maintaining high performance quality. So, to facilitate wider development and adoption of wireless technology at low cost,  Dialog Semiconductor, a leading provider of power management, Wi-Fi and Bluetooth® technology, has announced the production of its tiny power-efficient Bluetooth 5.1 SoC, the DA14531.

The chip, also known as SmartBond TINY™, is based on a powerful 32-bit ARM® Cortex™ M0+ with a complete set of analog and digital peripherals. Due to its architecture, this chip has the ability to be used as a standalone wireless microcontroller or as an RF data pipe extension with existing microcontrollers.


For a complete Bluetooth low energy system, the SoC requires six external passive components, a single clock source and a power supply. And with a size as small as 2.0 x 1.7 mm, electronics designers will find it easy to fit this chip into their product designs, such as beacons, active RFID tags, cameras, wireless routers, banking cards etc. and thus save development time, efforts and costs.

DA14531’s integrated DC-DC converter enables a wide operating voltage (1.1 to 3.3V) which allows the SmartBond TINY module to consume low power as possible. This is particularly useful in ensuring long battery life for running several applications and yet keep the costs low.

“The addition of SmartBond TINY and the module builds upon Dialog’s leading presence in the Bluetooth market. With the ability to turn any device, even disposable ones, into a connected application, the TINY SoC and module are opening new markets and driving the adoption of BLE beyond what was previously thought possible in today’s landscape,” said Sean McGrath, SVP, Connectivity and Audio Business Group of Dialog Semiconductor. “TINY and its module’s small size and power footprint, combined with Bluetooth 5.1 compliance, pave the way for the next one billion IoT devices.”
