On Semiconductor is sampling a Bluetooth 5-certified radio SoC, which the company claims is capable of providing faster data rate while maximising the system's battery life. Target applications for the device include wearables such as fitness trackers and smart watches, smart locks, and electronics like lighting or appliances.

The RSL10 capitalises on the increased data rate throughput capabilities of Bluetooth low energy technology, while optimising power consumption, according to the company. The SoC is ideal for applications using 1.2 and 1.5V batteries, and provides a voltage supply range between 1.1 and 3.6V without an external DC/DC converter.

The highly-integrated dual-core architecture is built around the user-programmable ARM Cortex-M3 processor, which provides clocking speeds up to 48MHz and the flexibility to support 2.4GHz proprietary protocol stacks. Also featured is an ultra-low-power 32-bit Dual-Harvard Digital Signal Processing (DSP) system, which enables signal processing intensive applications such as wireless audio codecs.

To accelerate customer design in and reduce customer time to market, ON Semiconductor is rolling out a complete development platform, including hardware board, software tools, full documentation set and a large range of Bluetooth protocols and firmware profile libraries.

The RSL10 SoC is currently sampling in an ultra-miniature 5.50mm2 51-pin WLCSP package. Samples of the 6mm x 6mm 48-pin QFN are planned to be available at the end of April.
