The first family from Fujitsu based on the ARM® Cortex™-R4 core is called FCR4-Cluster family and is dedicated to automotive instrument cluster applications.

The FCR4 Cluster family of devices has been especially designed to offer an innovative, scalable solution for hybrid clusters,
which are combining traditional meters and graphical displays.
With their embedded flash the FCR4 MCUs and SOCs can serve as single chip solutions or operate as companion chips for other
devices to build high performance systems also for virtual/free programmable clusters.
FCR4 devices are offering a powerful architecture based on the ARM® Cortex™-R4 core and Fujitsu's 2D IRIS graphics engine.
They include the required safety and security features, allow for today's requirement for low power consumption and are developed
to fulfill highest automotive quality standards.
