Renesas’ Smart Cluster reference solution includes full cluster functionality with additional features for dashboard market segments. Key features of this solution include a stepper motor for RPM, segmented LCD display for speed, odometer, trip, clock, fuel level, gear, distance to empty (DTE), average, and a special area for displaying simple user-defined logos and direction.

This innovative design adds wireless modules for communicating with smartphones. With this added feature, a traditional cluster becomes a smart cluster, enabling added functionality such as diagnostics, navigation, etc.
