Car microprocessor

Renesas has released the SH7761 32-bit microprocessor for car information systems such as telematics and hands-free equipment.

Operation at 400 MHz is twice as fast as the earlier device and enhanced peripheral functions enable systems with improved performance and lower cost.

Features include: high processing performance of 720 MIPS at maximum operating speed of 400 MHz. The device incorporates the SuperH family’s top-end SH-4A CPU core.

Since this CPU core is widely used in SH-Navi series system-on-chip devices for in-vehicle information equipment such as car navigation systems, existing program code can be re-used.

There is a DDR2-SDRAM (double data rate 2 synchronous DRAM) interface for faster-speed data transfer.

The DDR2-SDRAM interface allows connection of DDR2-SDRAM, which is faster than the SDRAM supported by the SH7760.

Essential on-chip peripheral functions are provided to implement the main functions of next-generation telematics and hands-free systems with a single chip.

Bluetooth 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.

A NAND flash memory interface and an SD card interface have been newly added, and to simplify the configuration of an in-vehicle LAN, two CAN interfaces have been equipped and a MOST (media oriented systems transport) interface, commonly used for data applications, has been added.
