For IoT developers who are keen to leverage the faster data rates of Bluetooth 5 while optimising system size and battery life, ON Semiconductor has designed a tiny multi-protocol Bluetooth 5 certified chip geared for wearables such as fitness trackers and smart watches, smart locks, and electronics like lighting or appliances.
The RSL10 is claimed to offer power-efficient operation for a wide range of applications with 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, and provides a voltage supply range between 1.1 and 3.6 V without an external DC/DC converter, ON Semi said.
Featuring a dual-core architecture, the highly-integrated SoC is based on 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.
The powerful dual-core architecture of the chip is complemented by high-efficiency power management units, oscillators, flash, and RAM memories, a DMA controller, and peripherals and interfaces.
“Advancements in wearables and health and wellness devices are continually pushing for reductions in system size and optimization of battery life,” stated Bob Klosterboer, executive vice president and general manager of the Analog Solutions Group at ON Semiconductor.
“Using our decades’ worth of experience and expertise developing ultra-low-power System-on-Chips (SoC) targeting hearing aids, we have developed a solution that sets new benchmarks in power consumption.”
To accelerate development, the firm also makes 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 mm2 51-pin WLCSP package. Samples of the 6×6 mm 48-pin QFN are planned to be available at the end of April.
