Development board hosts Renesas ARM Cortex-A9 core MCU

January 27, 2015 // By Graham Prophet
Distributor Rutronik has Vekatech’s VK-RZ/A1H development board which carries the RZ/A1H embedded microprocessor from Renesas, an ARM Cortex-A9-based MCU.

The embedded microprocessor RZ/A1H runs at up to 400MHz clock speed; integrates up to 10MB of on-chip RAM, and has an OpenVG compatible graphics accelerator, dual LCD-drivers and camera inputs. The internal SRAM can hold two layers of WXGA size images making external SRAM redundant. Using serial QSPI-flashes enables compact HW-designs with low pin count ICs.

The VK-RZ/A1H board is equipped with the 10 MB-version of the RZ/A1H in the BGA256 package. The processor has 2x32 MB SDRAM and 2x8 MB QSPI-flash next to it. Debugging can be performed via standard J-TAG connector. An additional USB function interface, provided by a RL78/G1C connectivity microcontroller, is connected to the RZ/A1H’s UART. The Board Support Package includes U-Boot, Linux-GCC, FreeRTOS and CycloneTCP, both compiled for EWARM from IAR and can be downloaded from Vekatech’s website ( An SD-Card bootloader allows for easy loading and running of applications from the internal SRAM, SDRAM or serial flash.
