Renesas: 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.

Key Features:

  • 2D graphics accelerator supporting OpenVG1.1 API [option]
  • The Display Unit(DU) supports a RGB888(24bit full-color) output.
  • Built-in Gigabit Ethernet MAC
  • DDR2/DDR3-SDRAM controller
  • SH-4A superscalar CPU core with operating up to 533MHz
  • Built-in USB2.0 High speed Host/Function controller
  • Other optional functions
