OnSemi launches connected health chip at MWC
February 28, 2017
At this week’s Mobile World Congress in Barcelona, On Semiconductor is introducing a multi-protocol system on chip (SoC) that can support wireless functionalities emerging in the IoT and connected health and wellness sectors without compromising battery life or overall system size.
The RSL10 multi-protocol Bluetooth 5 certified radio SoC is targeted at applications such as wearable fitness trackers and smart watches, smart locks, and electronics lighting or appliances.
The device capitalises on the increased data rate throughput capabilities of Bluetooth Low Energy, while optimising power consumption. It provides power-efficient operation for a wide range of applications. Suitable applications include those using 1.2 and 1.5V batteries and a voltage supply range between 1.1 and 3.6V without an external DC-DC converter.
“Advancements in wearables and health and wellness devices are continually pushing for reductions in system size and optimisation of battery life,” said Bob Klosterboer, executive vice president at Arizona-based On Semiconductor. “Using our decades’ worth of experience and expertise developing ultra-low-power systems-on-chip targeting hearing aids, we have developed a solution that sets new benchmarks in power consumption.”
The 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 low-power 32bit dual-Harvard digital signal processing, which enables signal processing intensive applications such as wireless audio codecs.
To accelerate design and reduce time to market, the company is making available a development platform including hardware board, software tools, documentation, and Bluetooth protocols and firmware profile libraries. The device is sampling in a 5.50mm2 51-pin WLCSP package. Samples of the 6 by 6mm 48-pin QFN are planned for the end of April.
