The SH77650 provides the same image recognition functions as Renesas Electronics's existing SH7774 (600 MHz operation) high-performance SoC product for car navigation systems. Developed as a dedicated image recognition processing IC device, the new SoC product delivers a superior cost-performance through optimized functionality and performance.

The SH77650 incorporates the SH-4A CPU core. Its processing performance is 540 MIPS at its maximum operating frequency of 300 MHz. This excellent processing performance makes it possible to realize powerful systems. The SH77650 also incorporates many peripheral functions suitable for image recognition applications. In addition to a high-performance image recognition processing accelerator, there is a three-channel video input interface, a display function supporting a screen of maximum WVGA size (850 x 480-pixel), a dedicated six-channel DMA controller, three timer channels, a two-channel serial interface, and a two-channel CAN interface for in-vehicle LANs. This variety of on-chip peripheral functions covers the main tasks performed by in-vehicle image recognition systems.
