The huge 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 10MB version of the RZ/A1H in the package BGA256. The processor has 2x32MB SDRAM and 2x8MB QSPI-flash next to it. Debugging can be performed via standard J-TAG connector. Additional USB function interface, provided by a RL78/G1C connectivity microcontroller is connected to RZ/A1H’ 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.
