Radar MCUs With High Computing Power For ADAS

Renesas has announced new 32-bit automotive radar microcontroller series specifically designed for radar applications in future advanced driver assistance systems (ADAS) and autonomous driving vehicles.

New RH850/V1R MCUs deliver high computing and optimized DSP to enable higher accuracy and safety for applications such as advanced emergency braking, adaptive cruise control and collision avoidance.

The first product in the new RH850/V1R MCU series is the RH850/V1R-M, which includes a digital signal processor (DSP) and high speed serial interfaces and is specifically designed for middle- to long-range radars. The DSP performs radar specific algorithms such as fast fourier transforms (FFTs), beamforming, windowing, at high speed and with low power consumption, according to the firm.

The RH850/V1R-M features two G3MH CPU cores operating at 320 megahertz (MHz), said to be the highest performing cores in the RH850 series. There is a high speed flash of 2 MB and a 2 MB internal RAM. The MCU is also said to fulfill the highest temperature requirements in the industry featuring a junction temperature of 150°C.

A large 2MB capacity RAM allows the MCU to handle all specific calculations on radar cube data such as range and velocity FFTs, digital beam forming, constant false alarm rate (CFAR) and peak detection. The embedded flash allows use of less PCB space and better real time behavior.

Samples of the RH850/V1R-M and the DSP math library will be available from second half of 2017. Samples will be priced at US$30 per unit. Mass production is scheduled to begin in November 2018.

The firm said it will also avail flexible programmable complete toolchain with C/C++ compiler, debugger, simulation models and detailed performance profiling tools for developers to start their development immediately with the RH850/V1R-M.
