Bluetooth 5 certified RF System-on-Chip for IoT and Connected Health & Wellness

ON Semiconductor has introduced a highly flexible, ultra-miniature multi-protocol Bluetooth 5 certified radio System-on-Chip (SoC) - RSL10 - capable of supporting the advanced wireless functionalities emerging in the IoT and Connected Health & Wellness sectors without compromising battery life or overall system size. Target applications for this device include wearables such as fitness trackers and smart watches, smart locks, and electronics like lighting or appliances.

The RSL10 capitalizes on the increased data rate throughput capabilities of Bluetooth low energy technology, while optimizing power consumption. The sophisticated SoC provides an incredibly power-efficient operation for a wide range of applications with its superior overall power profile, including some of the best numbers in the industry for peak Rx in Receive Mode and Deep Sleep Modes. Unlike competing solutions, it is ideal for applications using 1.2 and 1.5 V batteries, as it has a voltage supply range between 1.1 and 3.6 V 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 48 MHz and the flexibility to support 2.4 GHz 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.

RSL10​ Key Features:

  • Ultra-Low-Power: RSL10 provides an incredibly power efficient operation for a wide range of applications with its superior overall power profile, including some of the industry's best numbers in Deep Sleep Mode (62.5 nW) and Rx in Receive Mode (7 mW).
  • Advanced Multi-Protocol Wireless Functionality:
  • Rx Sensitivity: -94 dBM
  • Transmitting Power: -17 to +6 dBm
  • Supports Bluetooth low energy and 2.4 GHz proprietary/custom protocols
  • Supports Firmware Over The Air (FOTA)
  • Flexible Voltage Supply Range (1.1 and 3.6 V): Supports devices using 1.2 and 1.5 V batteries without a required external DC/DC converter
  • Ultra-Miniature: RSL10 is offered in a 5.50 mm2 WLCSP (Production: May 2017) and a 6 x 6 mm QFN (Production: July 2017). For added miniaturization, the radio SoC can be integrated into System-in-Package (SiP) solutions which combine RSL10 with a custom ASIC.
  • Sophisticated Dual-Core Architecture: Features a programmable ARM Cortex-M3 processor for clocking speeds up to 48 MHz and the flexibility to support 2.4 GHz proprietary and custom protocol stacks. An embedded Digital Signal Processor (DSP) enables signal processing intensive applications, such as wireless audio codecs.
  • On-Chip and Software Wireless Support: Features a 2.4 GHz Radio Frequency Front-End (RFFE) and a Bluetooth 5 certified baseband controller which supports 2 Mbps data rates. A wide range of supported Bluetooth low energy protocols are provided in the RSL10 development tools kit.
  • Highly-Integrated System-on-Chip (SoC): The powerful dual-core architecture is complemented by high-efficiency power management units, oscillators, flash, and RAM memories, a DMA controller, and peripherals and interfaces.
  • Other Key Technical Features:
  • 384 kB of flash memory
  • IP protection feature to secure flash contents
  • Configurable analog and digital sensor interfaces (GPIOs, LSADs, I2C, SPI, PCM)

To accelerate customer design in and reduce customer time to market, ON Semiconductor is making available 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 5.50 sq. mm 51-pin WLCSP package. Samples of the 6 x 6 mm 48-pin QFN are planned to be available at the end of April.
