Renesas Electronics: SH7734 - SuperH Microcontroller Supporting High-Resolution Displays and Gigabit Ethernet

Renesas Electronics and its subsidiary, Renesas Mobile Corporation announced the availability of its new 32-bit microcontroller (MCU), the SH7734

The SH7734 has a CPU core with a maximum operating frequency of 533 MHz and on-chip 4-way set-associative cache memory with 32 kilobytes each for instruction and data.

The SH7734 is equipped with a built-in graphics accelerator function that conforms to the OpenVG 1.1 specification. As a display controller, it has a built-in display unit that supports RGB888 digital output. A built-in Gigabit Ethernet controller enables high-speed data transfer over a network. Furthermore, the built-in controller used for main memory supports both DDR2 and DDR3-SDRAM.

Other on-chip peripheral functions include USB 2.0 host/function, a DMA controller, serial interface, NAND flash interface, timers, serial sound interface, SD host interface, and multimedia card interface.
