Advanced automotive security together with concurrent dual Wi-Fi 6E and Bluetooth 5.3 are enabled in NXP’s automotive wireless connectivity portfolio with the introduction of the AW693 wireless connectivity device.

The integrated AW693 enables multiple secure connections within the car, supporting the transition to software-defined vehicles, said NXP. It enables concurrent dual Wi-Fi 6E and Bluetooth 5.3 connections and is protected by NXP’s integrated Edgelock secure subsystem.

Targeting telematics and in-vehicle infotainment, the AW693 supports connectivity across multiple automotive platforms when combined with NXP’s i.MX 8 and 9 series of applications processors. This enables secure delivery of the over the air software updates and also facilitates secure connections between various systems and mobile devices inside the car.

In addition to updates to ensure vehicle platforms are equipped with the latest features and security, new and future vehicles will require constant connection between vehicle systems, said NXP. This will include the secure upload and download of sensor information, camera feeds, diagnostics data and other features, as well as communication between the vehicle and mobile devices.

This requires low latency and simultaneous multi-band connectivity to support both legacy and new devices. It also needs connection stability to allow seamless communication throughout a vehicle. According to NXP, its AW693 can be used with its Concurrent Dual Wi-Fi to incorporate an access point-like design approach.

The AW693 offers concurrent dual Wi-Fi 6E and Bluetooth 5.3 operation, with integrated 2.4GHz and 5.0 to 7.0GHz TX power amplifiers, RX low noise amplifiers, Tx/Rx switches and a full Bluetooth radio. NXP’s integrated EdgeLock secure subsystem supports hardware crypto-accelerated secure boot, key management, firmware authentication, secure life cycle management and anti-rollback protection. The AW693 is AEC-Q100 Grade 2-compliant.

NXP’s i.MX 95 family quickly and easily integrates the AW693 to enable safety-capable, secure automotive platforms and offers efficient machine learning acceleration, said the company2, adding that this helps to simplify development and reduce costs.

The AW693 is part of a portfolio of automotive wireless connectivity solutions that includes the AW692, the AW690, the AW611 and the Q9098.

A combined digital instrument cluster and connectivity reference platform delivers high performance graphics and rich connectivity for an advanced two-wheeler user experience, said NXP Semiconductors.

It is designed for mass-market two-wheelers, including motorcycles, electric scooters and commuter bikes. It combines the i.MX RT1170 crossover microcontroller with AEC-Q100 Grade 3 qualification. This helps reduce system costs due to the highly integrated nature of the i.MX RT1170, which does not require expensive external memory or power management subsystems, said NXP. The NXP Wi-Fi and Bluetooth device drivers are pre-integrated into the MCUXpresso SDK (software development kit), along with display and GNSS, making it easy for developers to create their own twowheeler connected cluster. The dual-core i.MX RT1170 crossover MCU provides a wide range of interfaces for connecting peripherals, such as WLAN, Bluetooth, GPS, audio, displays, and camera sensors, plus a vector graphics accelerator. The i.MX RT1170 crossover MCU’s rich graphics capabilities are supported by NXP’s broad ecosystem of partners, including Altia, The QT Company, Embedded Wizard by TARA Solutions, and Crank.

The reference platform also includes the integrated AW611 a highly integrated dual-band Wi-Fi 6 and Bluetooth/Bluetooth Low Energy 5.2 single-chip solution with AEC-Q100 Grade 2 qualification. This high degree of integration enables efficient coexistence between internal radios, as well as with external radios, while helping to reduce system costs, said NXP.

The KW45 secure wireless access microcontroller delivers secure vehicle access and vehicle location services. Its three-core architecture integrates a 96MHz Arm Cortex-M33 application core, a dedicated Cortex-M3 radio core and an isolated EdgeLock secure enclave. It also integrates a Bluetooth Low Energy 5.3-compliant radio that supports up to 24 simultaneous secure connections.

Connected digital displays with rich graphics are essential to the safe operation of two-wheeler electric vehicles, which are rapidly gaining in popularity for transport around cities. The displays can provide critical information that allows drivers to compare navigation details to battery levels and health, as well as the location of charging points.

Telemetry in the field also provides OEMs with important information about usage and battery lifetimes.

NXP’s digital instrument cluster and connectivity reference platform is designed to allow OEMs to deliver these capabilities, while also enabling a wide variety of different connectivity use cases designed to improve the user experience, for example three-way Bluetooth pairing between the phone, scooter’s digital cluster, and headphones, rider and pillion music sharing or even location capabilities such as “find my bike” in a parking lot.

“Not only does the digital instrument cluster inform the driver of the state of their vehicle, it also represents the main way a driver can customise their vehicle to their preferences,” said Dan Loop, vice president and general manager, Automotive Edge, NXP. “NXP’s digital instrument cluster and connectivity platform enables consistent updates and customizations to support the latest safety, security and connectivity features, all in a platform that balances performance and wireless connectivity capabilities with cost considerations.”

The platform enables high-performance graphics and rich connectivity use cases such as hands-free calling, wireless pairing for smartphone projection, Bluetooth audio, over the air (OTA) updates, cloud connectivity, fleet management, secure vehicle access and vehicle location.
