Realize Car Infotainment System Controller and Network Functions on One-Chip
Renesas Electronics Microcontrollers for Car Infotainment Systems, V850E2/Sx4-H
TOKYO, Japan, June 8, 2011 — Renesas Electronics Corporation (TSE: 6723, Renesas), a premier provider of advanced semiconductor solutions, today announced the availability of six new 4th-generation (X4 generation) V850-based S-series microcontrollers (MCUs), ideally suited for car infotainment systems and networking. The new products include two MCUs from the V850E2/Sx4-H group with 100 pins, two MCUs from the V850E2/SJ4-H group with 144 pins and two MCUs from the V850E2/SK4-H group with 176 pins.
The evolution in car infotainment systems and networking within the car requires the introduction of protocols such as Ethernet and MOST (Media Oriented System Transport) to support high bandwidths and reliable data transfers. This is in addition to the well-established automotive networks such as CAN and IEBus (Inter Equipment Bus) also supported by Renesas' V850E2/Sx4-H family of MCUs.
Key features of the V850E2/Sx4-H MCUs:
(1) Enhancement of networking functionality
By adding an Ethernet PHY and MOST network interface controller to the V850/E2/Sx4-H MCUs, additional networking functionality is now possible. Routing of system data, e.g. from the diagnostic Ethernet channel to the MOST bus, as well as the routing of audio streams from/to MOST to up to eight I²S™ bus interfaces is supported.
(2) High performance for networking and system control in parallel
The V850E2/Sx4-H MCUs incorporate the 32-bit V850E2M CPU core, which has an excellent performance ratio of 2.5 DMIPS/MHz (Dhrystone MIPS [million instructions per second] per megahertz), and capable of covering a performance range up to 160 MHz (at 400 MIPS). This enables the device to perform networking functionality in parallel to all system controller tasks.
(3) Wide-range lineup for several applications
The integrated flash memory ranges from 2 megabytes (MB) down to 1 MB while the fast SRAM scales from 192 kilobytes (KB) down to 96 KB. Further, the wide lineup of QFP packages from 100- to 176-pin together with flexible pin assignment and application-oriented peripheral selection allow cost optimal choice of solutions for applications.
(4) Rich development environment
A lineup of Renesas hardware tools, including the IECUBE2 (Note 1) as a full-specification emulator and the E1 emulator as an on-chip debugging emulator, is available for the V850E2/Sx4-H MCUs. Further, Renesas' existing integrated environment CubeSuite+ and MINICUBE are also usable.
With the introduction of the V850E2/Sx4-H family, Renesas continues the success of the market-leading V850/S-Series with the enhancement of network-oriented support of MOST and Ethernet.

Pricing and Availability
Sample shipping has begun for the first device in the family, the 176-pin V850E2/SK4-H, while the other family members with 144 and 100 pins will follow later. Sample pricing is US$20 per unit and mass production is scheduled to begin in June 2012. (Pricing and availability are subject to change without notice.)

About MOST Technology
MOST (Media Oriented Systems Transport) is a multimedia networking technology developed by MOST Corporation. MOST is optimized for use in cars and other applications, and it enables the transport high Quality of Service audio and video together with packet data and real-time control over a single transmission medium at maximum transfer speed of 150 megabits. MOST can use plastic optical fiber or electrical unshielded or shielded twisted pair wire physical layers that meet automotive environmental requirements. Today, MOST is used in over 100 car models as the communication backbone for their information and entertainment equipment that perfectly meet the rising demand for high-quality playback of music and movies, packet-data communication of information such as traffic information, higher-speed data transfer, and to lighter bodies to improve the fuel economy of cars. More information about MOSFT can be found at http://www.mostcooperation.com/home/index.html
The adoption of Ethernet, a network communication widely implemented in FA equipment and industrial application, is also in progress as a transmission medium to enable data communication from outside the car during failure diagnosis and software update.
