"R-Car M1A" and "R-Car M1S" are SoCs for midrange systems.These device had high adoption rates in car infotainment systems like dashboard mounted car navigation systems. "R-Car M1 series " are developed for the mid-range systems and supports 1080 HD video and advanced graphics displays while offering low-power consumption.
- Low power consumption while providing high performance multimedia through the integration of dedicated circuits for processing of 1080 HD video and audio
- Dedicated power supply IC for use in a voltage regulator enables low-power consumption and quicker time to market
- Realistic 3D images achieved with the latest 3D Graphics Processing Unit (GPU)
- ARM Cortex-A9 and Renesas Electronics SH-4A architectures with hardware accelerators enabled by Renesas Electronics' high-quality software/middleware
