A multiprotocol, Bluetooth 5-certified radio system-on-chip, On Semiconductor’s RSL10 requires just 62.5 nW in deep sleep mode and 7 mW in receive mode, optimizing battery life in fitness trackers, smart watches, and other  IoT and connected health and wellness applications. With its ARM Cortex M3 processor and LPDSP32 DSP core, the highly integrated RSL10 supports Bluetooth low-energy technology and 2.4-GHz proprietary protocol stacks without sacrificing power consumption.
 
The radio system-on-chip is intended for designs using 1.2-V and 1.5-V batteries and accommodates a voltage supply range of 1.1 V to 3.6 V without requiring a DC/DC converter.
