—Renesas Electronics Corp. and its cell phone chip subsidiary, Renesas Mobile Corp., announced a series of SoCs that emphasize low power consumption for dashboard-mounted car navigation systems and advanced human machine interfaces.
Renesas (Tokyo) said the R-Car M1 series of SoCs are the first members of the company’s R-Car series, representing the integration of the company’s SH-Navi serie and EMMA Car series products. These devices have had high adoption rates in automotive infotainment systems, such as dashboard-mounted car navigation systems, according to Renesas.
The R-Car M1 series SoCs have been developed for mid-range systems, which are expected to become the highest volume segment in the market, and include the R-Car M1A and R-Car M1S as its lineup, Renesas said.
According to Renesas, R-Car M1 SoCs integrate dedicated circuitry for intelligent multimedia processing that saves approximately 92 percent of power in full 1920 x 1080-pixel high-definition video decoding compared with executing the same function in software on previous products. The devices also feature a dedicated power supply IC for use in a voltage regulator that reduces power consumption by approximately 20 percent compared with the company’s existing products, Renesas said.
R-Car M1 SoCs also include a PowerVR SGX graphics core, which enhances 3-D and incorporate ARM Cortex-A9 and Renesas SH-4A CPU cores operating at a maximum 800 megahertz to deliver processing performance of up to 3.7 giga instructions per second, Renesas said.
Samples of the R-Car M1 series are scheduled to be available in May, Renesas said.
The R-Car M1A SoC sample will be priced at $70 and the R-CAR M1S SoC at $65,
the company said. Mass production is scheduled to begin in June 2012.
