Radar Microcontroller

S32R294

Roll over image to zoom in

The S32R294 MCU enables customers to build scalable, safe and secure, automotive RADAR systems with balanced performance at an attractive power level dedicated to Corner and Front Radar applications.

The S32R294 provides additional family scalability when compared to the previous device, S32R274. It provides up to 5.5 MB SRAM, an additional MIPI CSI-2 interface, along with a doubling of the clock frequency for the cores. This results in a range of parts that covers existing radar application use cases and gives overhead for future application expectations.
