MCUs Serve Up Solutions for Car Infotainment
Dashboard Dazzle
As automotive dashboard displays get more sophisticated, information and entertainment are merging into so-called infotainment systems. The new systems are driving a need for powerful MCU solutions that support the connectivity, computing and interfacing requirements particular to these designs.
Microcontroller (MCU) vendors have a rich legacy of providing key technologies for nearly every aspect of an automobile’s electronics—everything from the powertrain to the braking system to dashboard displays. In recent years, they’ve taken on a new set of challenges as demands rise for ever more sophisticated “infotainment” systems. Advanced touchscreen, processing, networking, voice recognition and more are parts of these subsystems tasked with providing drivers with information and entertainment suited to today’s demands—demands that must rival or exceed what’s possible in a modern smartphone or tablet. And, as driverless cars inch toward mainstream reality, that hunger for rich infotainment functionality will only increase.
In order to meet those system design needs, MCU vendors are keeping pace with highly integrated chip-level solutions and embedded software tailored specifically to address various aspects of the automotive infotainment challenge. Over the past 12 months, MCU companies have announced products aimed at everything from advanced dashboard graphics to connectivity solutions to security technologies. At the same time, many have announced milestone design wins that illustrate their engagement with this dynamic sub-segment of automotive system development.
SMARTPHONE SUPPORTExemplifying these trends, in July Cypress Semiconductor announced that Pioneer integrated Cypress’ Wi-Fi and Bluetooth Combo solution into its flagship in-dash navigation AV receiver. The solution enables passengers to display and use their smartphone’s apps on the receiver’s screen via Apple CarPlay (Figure 1) or Android Auto, which prov
