New Renesas SoC targets entry level, emerging market infotainment applications

August 26, 2011 // By Christoph Hammerschmidt
Renesas Electronics announced a new member of its R-Car series of automotive systems-on-chip (SoCs), the R-Car E1, offering low power consumption and high system integration targeting the cost-sensitive market of car navigation and multimedia systems including high-end car radios.

With the R-Car E1 SoC, Renesas intends to strengthen its position in entry navigation systems, as this device offers a good balance between system integration and cost. The R-Car E1 is powered with a single ARM CortexTM-A9 32-bit RISC CPU core (enhanced with NEONTM extension) running at 533 megahertz MHz, which achieves a maximum processing power of 1,330 Dhrystone million instructions per second (DMIPS). The Graphics Processor Unit (GPU) is Imagination Technologies' PowerVRTM SGX531 and processes up to 14M triangles/s and is capable of delivering up to 1.4 gigaflops for accelerated graphics.

To help customers minimize board space and costs of their navigation solutions, targeting emerging markets and cost-sensitive applications, R-Car E1 SoC has a balanced selection of integrated peripherals and functions. With multiple channels of 10-bit A/D converters, customers can simplify the interface to gyroscopes and accelerometers. The R-Car E1 SoCs also offers CD-ROM hardware-decoding capabilities and media interfaces for digital formats such as SD and USB.

Two output displays are supported - one output display is a digital RGB interface targeted for the main screen, while the second is an analog output supporting PAL/NTSC formats, enabling cost-effective, rear seat entertainment. The integrated digital-camera interface facilitates the integration of backup-camera or external video content. The R-Car E1 video processing unit (VPU) is capable of decoding up to 720p HD video codecs.

Equipped with various standard and automotive communication interfaces (CAN, MOST, Ethernet, UART, SPI, I²S, I²C) the R-Car E1 SoCcan handle further external devices and can be linked into common automotive networks.

Samples of Renesas' R-Car E1 SoCs are available now, equipped in a 429-pin BGA (ball grid array) package. Mass production is scheduled to begin in June 2012. at a rate of 100,000 units per month in June 2013. (Availability is subject to change without notice.)
