Renesas Technology Releases SH7761 32-Bit Microprocessor for Car Information Equipment such as Telematics and Hands-free Systems

High-speed operation at 400 MHz, which is twice as fast as the previous Renesas Technology product, and enhanced peripheral functions, enabling improved performance while lowering system cost

SAN JOSE, Calif. —May 28, 2009—Renesas Technology America, Inc., today announced the SH7761, a 32-bit microprocessor for car information equipment, such as telematics devices providing travel services via wireless communication links and hands-free systems, that delivers high-speed operation at 400 MHz and advanced features essential for next-generation systems, including high-speed communication, sophisticated voice recognition, and improved connectivity with onboard LANs and memory cards. Sample shipments will begin in August 2009.

Features of the SH7761 are summarized below.

High processing performance of 720 MIPS at maximum operating speed of 400 MHz

The SH7761 incorporates the SuperH*1 Family’s top-end SH-4A CPU core and achieves processing performance of 720 MIPS at a maximum operating frequency of 400 MHz, twice as fast as the earlier SH7760. This enables it to support the increasingly sophisticated voice recognition processing functionality (such as the ability to respond to natural language input) essential for hands-free applications.

The SH-4A core is upward-compatible with the SH-4 core of the existing SH7760.

Since this CPU core is widely used in SH-Navi Series*2 system-on-chip (SoC) devices for in-vehicle information equipment such as car navigation systems, existing program code can be reused and software development cycles shortened.

High-speed DDR2-SDRAM interface for faster data transfer speed

The DDR2-SDRAM (Double Data Rate 2 Synchronous DRAM) interface allows connection of DDR2-SDRAM, which is faster than the SDRAM supported by the earlier SH7760. This enables data transmission at higher speeds and improved system performance overall.

Integration on a single chip of peripheral functions required by next-generation equipment, helping to reduce overall system cost

A wide variety of on-chip peripheral functions are provided in order to implement the main functions of next-generation telematics and hands-free systems with a single chip. Bluetooth*3 is used for connections with mobile phones, and a high-speed serial communication interface (max. 4 Mbps) is provided to accommodate Bluetooth modules with Bluetooth 2.0 + EDR support. Also included are a 2-port USB interface supporting USB 2.0 high-speed mode for connecting portable music players and multiple sound interfaces for voice input and output.

In addition, a NAND flash memory interface and a SD card*4 interface have been newly added. To simplify the configuration of an in-vehicle LAN, the 2 CAN*5 interfaces, the in-vehicle networking standard for connecting onboard electronic devices for control applications, has been equipped, and a MOST (Media Oriented Systems Transport) interface, commonly used for data applications, has been newly added. This full complement of peripheral functions reduces the total number of components required by the system; thereby, helping to reduce the overall cost.

The automotive industry continues to add telematics and hands-free equipment to its products, especially in Europe and North America. In addition to supporting core features such as a hands-free phone, these systems are evolving into connectivity devices, including connectivity to portable consumer devices.

Today, telematics and hands-free devices support increasingly sophisticated voice recognition interfaces, as well as high-speed connections with mobile phones, and have the ability to connect entertainment devices such as portable music players. This has generated demand for microprocessors with higher processing performance capable of handling these functions.

Renesas Technology already mass produces the SH7760, a microprocessor for telematics and hands-free devices with processing performance of 360 MIPS at its maximum operating speed of 200 MHz. The new SH7761 32-bit microprocessor is designed to respond to the above-mentioned demand. It is built around the high-performance SH-4A CPU core, which has an established track record in in-vehicle information applications such as car navigation systems and integrates, on a single chip, the main functions required by telematics and hands-free devices from among Renesas Technology’s wide range of peripheral function IP resources.

In addition to the peripheral functions mentioned above, the SH7761 incorporates standard on-chip functions such as serial interfaces (serial communication interface and I2C bus interface) and an A/D converter.

The package used is a 449-pin BGA (21 mm ´ 21 mm).

The SH7761 also has an on-chip debug function that supports real-time debugging at the microprocessor’s maximum operating frequency. The E10A-USB on-chip debugging emulator, which connects to a PC via a USB port, is available as a development environment.

A reference platform equipped with a variety of interfaces is available for use in system development by the customer. This platform enables product development to proceed efficiently. The reference platform is scheduled to become available, along with samples of the SH7761, in August, 2009.

Future plans call for the release of a high-speed version to support more sophisticated voice recognition functions, as well as a low-end version with a simplified function set. There will also be a need for product versions providing interoperation with car navigation systems and support for a variety of high-speed interfaces. Renesas Technology plans to continue to release new products in a timely manner in response to evolving market demand.
