An electrification revolution is underway, transforming all sectors of the automotive industry including two-wheeled vehicles
ranging from motorcycles to scooters and e-bikes of all classes and price points. While most motorcycles and scooters are
powered by traditional internal combustion engines (ICE), electric vehicle (EV) models are becoming increasingly popular with
rising fuel prices and consumer preferences for economy and ease of use.
Electric two-wheelers offer safe, easy-to-ride, smart, green and simpler alternatives to ICE-powered motorcycles and scooters.
They are convenient to power and easy to connect to intelligent systems, enhancing the rider’s safety and comfort. While basic,
low-cost two-wheelers serve the needs of daily commuting in developing parts of the world, high-end electric motorcycles and
scooters quench the desire for higher speed, longer range and adventure for riders in affluent markets.
EV companies are actively developing value-added digital features, such as connected digital instrument clusters, to encourage an
increasing number of drivers to switch to electric vehicles. Leveraging this shift in the automotive industry, two-wheel vehicle
manufacturers are integrating digital clusters into their latest models. The clear, crisp and real-time display of vital
information and vehicle parameters, such as road speed, revolutions per minute, location, navigation, ambient temperature and
range, helps riders avoid distractions and improves the overall riding experience.
New Reference Platform Eases Development of Two-Wheeler Digital Clusters
To help accelerate the development of full-color thin-film transistor (TFT) displays for two-wheelers, NXP has built a combined
digital instrument cluster and connectivity reference platform designed for mass-market two-wheelers, including motorcycles,
electric scooters and commuter e-bikes. The reference platform enables high-performance graphics and rich connectivity use cases
such as hands-free calling, wireless pairing for smartphone projection, Bluetooth audio/video, over-the-air (OTA) updates, cloud
connectivity, fleet management, secure vehicle access and vehicle location.
Two-Wheeler Connected Digital Cluster Reference Design
To deliver a cost-effective system designed to enhance the user experience of two-wheel mobility, the reference platform combines the following NXP components:
The high-performance i.MX RT1170 crossover microcontroller (MCU)
The highly integrated AW611
single-chip Wi-Fi® 6 and Bluetooth®/Bluetooth Low Energy (BLE) audio connectivity solution
The secure, long-range KW45
wireless access MCU featuring a Bluetooth Low Energy 5.3-compliant radio

Turnkey Reference Platform for Faster, Easier Development
NXP’s connected digital cluster reference platform enables OEMs to deliver essential instrument cluster capabilities for
two-wheelers while also supporting a wide variety of connectivity use cases designed to improve the rider experience. Key
capabilities include three-way Bluetooth pairing between a smartphone, the digital cluster and headphones; rider and passenger
music sharing; and location capabilities such as “find my bike” in a parking lot, phone-based navigation and EV charging
Hands-Free Calling and Bluetooth Audio
Bluetooth facilitates the connection of the rider’s mobile phone to the two-wheeler digital cluster. Once paired, call logs and
contact information can be shared and displayed on the intelligent dashboard, enabling hands-free calling. Message alerts and
incoming calls also can be displayed on the screen. While the two-wheeler is stopped or parked, the rider can make outgoing
calls by touching the smart dashboard and routing calls through the mobile phone; incoming calls can be accepted or disconnected
using the display screen.
Implementing Bluetooth audio enables the rider, as well as the passenger in advanced use cases, to enjoy music streaming.
Connectivity from the dashboard to the helmet further enhances the rider experience. Riders also appreciate convenient audio
playback capabilities when stuck in traffic or while waiting for the two-wheeler battery to charge.
Secure Two-Wheeler Access
NXP’s KW45 MCU
with Bluetooth Low Energy, CAN and integrated secure enclave offers a low-cost connectivity option for secure two-wheeler
location tracking and access. In two-wheeler design, one KW45 MCU works with the RT1170 MCU in the instrument cluster while the
second KW45 is built into the rider's key fob. The KW45 MCU in the 2-wheeler could pair up with the key fob or even with the smartphone
when they’re in close proximity, around three meters. At that time, the rider’s side pings the i.MX RT1170 MCU for sound/light
indication, enabling easy spotting of the two-wheeler in a parking lot.
When the KW45 MCU in the two-wheeler digital cluster is registered in popular search applications, riders can use their
smartphone to track the location of the two-wheeler on a map and manually trigger the sound/light indication when in close
proximity. More advanced use cases include implementing a BLE smart tag tracking feature using global network of smartphones to
find a lost or stolen two-wheeler.
Reference Platform Expands Connectivity-Based Capabilities for Two Wheelers
- Receive real-time vehicle information including battery consumption, route, speed and travel distance
- Locate the nearest recharge stations, public parking spaces and other points of interest
- Share updates and alerts supporting the two-wheeler servicing schedule
- Lock and unlock the two-wheeler remotely
- Share safety issues and poor road conditions with traffic management and law enforcement
- Fleet management through the cloud
i.MX RT1170 MCU Brings Advanced Technology to Two-Wheelers
While NXP i.MX applications processors have been widely adopted in the automotive market for years, the
i.MX RT1170 crossover MCU
