"The world of automotive is evolving rapidly towards the emergence of the connected car, and connected in-car ecosystems" says John Leonard, Product Marketing Manager at Nordic Semiconductor. "This will expand from Bluetooth enabled smartphones and tablets being wirelessly linked to in-car user interfaces and audio systems to having a vast array of other factory-fitted elements being made wirelessly controllable and configurable.
"This will lead to connected in-vehicle ecosystems that contain 'swarms of wireless sensors' for driving experience enhancement, safety, and diagnostics. Examples will include intelligent seats, intelligent steering wheels, remote keyless entry [RKE] systems, intelligent mirrors, infotainment systems, and intelligent accident or incident proximity reporting. It also brings exciting opportunities for after-market equipment suppliers to deliver innovative in-car systems that communicate with each other and with smart mobile devices. The nRF51824 is the world's most powerful automotive qualified Bluetooth low energy SoC and as such is very well suited to these application demands."
Under-the-hood systems could also benefit from Bluetooth wireless functionality, because this would enable manufacturers to reduce the cost and weight of traditional cable looms to offer simpler factory assembly, maintenance, and replacement, plus increased fuel economy.
Leonard says that the list of potential connected car features and benefits is also unlikely to end there: "Wireless in-car charging of smart mobile devices is probably going to be one of the most popular connected car features of them all," he continues. "This is why the nRF51824 also includes support for Nordic's nRF5 SDK for AirFuel [wireless charging standard] which together with the Nordic S130 SoftDevice supports charging of multiple devices on a single charge surface."
With 256 kB Flash and 16 kB RAM, the nRF51824 is sampling now and is supplied in a 6x6 48-pin QFN package.
