Renesas Electronics has unveiled its first RH850-based, 32-bit, automotive radar microcontroller (MCU) series, the RH850/V1R, to deliver features required for enabling future advanced driver assistance systems (ADAS) and autonomous driving vehicles.
The RH850/V1R-M, the first product from the RH850/V1R Series, includes a digital signal processor (DSP, Note 1) and high speed serial interfaces, designed for middle- to long-range radars.

“With the expansion of ADAS and autonomous driving, sensors are fast becoming a key technology,” noted a Renesas statement. “Currently vehicles are being equipped with a broad spectrum of sensors such as cameras, lidar and ultrasonic sensors.
“In particular, radar sensors are required for ADAS applications, including advanced emergency braking and adaptive cruise control, because, unlike other sensors, radar sensors are not negatively affected by external environmental limitations which includes adverse weather conditions, such as rain, fog or whether the sun is shining or not.”
“Additionally, high precision sensing becomes critical in realising future autonomous driving to meet increasing requirements of range resolution, separation of objects and precision in measurement of velocity.
“This requires increased numbers of antennas and boosting of the signal processing performance.”
