2 INTRODUCTION TO NUDESIGN NK-N9H30 BOARD
The NuDesign NK-N9H30 solution uses an outstanding CPU core ARM926EJ-S, N9H30F61IEC
IC which runs up to 300 MHz and features the embedded 64MB DDR memory, with 16 KB I-
cache, 16 KB D-cache and MMU, 56 KB embedded SRAM and 16 KB IBR (Internal Boot ROM)
for booting from SPI Flash or booting from NAND Flash.
The NuDesign NK-N9H30 solution integrates touchscreen display, voice input/output, rich serial
port service and I/O interface, providing multiple external storage methods. It contains two kinds
of board, including the NuDesign NK-N9H30 board and NuDesign TFT-LCD5 board.
