Ultra-low-power multi-protocol BT5.0 certified

Offering the industry’s lowest power consumption, RSL10 helps provide devices like heart rate monitors with advanced wireless features while optimizing system size and battery life.

Unlike most other multi-protocol radio SoCs, RSL10 is specifically designed for applications using 1.2 and 1.5 V batteries, and supports a voltage supply range between 1.1 and 3.3 V without a required DC/DC converter. The highly-integrated radio SoC features a dual-core architecture and a 2.4 GHz transceiver, providing the flexibility to support Bluetooth low energy technology and 2.4 GHz proprietary or custom protocols.

With its Arm® Cortex®−M3 Processor and LPDSP32 DSP core, RSL10 supports Bluetooth low energy technology and 2.4 GHz proprietary protocol stacks, without sacrificing power consumption.
