A great number of present and future connected applications in vehicles ranging from smartphones to wireless sensors, intelligent seats and steering wheels to accident reporting systems will utilize the Bluetooth technology to communicate. For these applications, Nordic Semiconductor is introducing an automotive-version of its popular nRF51822 Bluetooth chip.
The new nRF51824 is qualified to the automotive AEC-Q100 stress test qualification for integrated circuits, and delivers the same feature range and performance as Nordic's field-proven nRF51822 Bluetooth low energy SoC (256kB Flash and 16kB RAM variant) upon which the nRF51824 is based.
"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 lead to connected in-vehicle ecosystems that contain 'swarms of wireless sensors' for driving experience enhancement, safety, and diagnostics. 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 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 [a major wireless charging standard] which together with the Nordic S130 SoftDevice supports charging of multiple devices on a single charge surface."
The nRF51824 is sampling now and is supplied in a 6x6 48-pin QFN package.
