Nuvoton NK-N9H20 and Its Features
N9H20 series is built on the ARM926EJ-S CPU@200MHz, synchronous DRAM, 2D BitBLT accelerator, LCD panel interface, USB 1.1 Host & USB2.0 HS Device core and integrated with JPEG codec, 32-channel SPU (Sound Processing Unit), ADC, DAC, for meeting various kinds of application needs for saving the BOM cost and makes the best choice for LCD application of cost/performance products. Maximum resolution is XVGA (1,024x768)@TFT LCD panel. The 2D BitBLT accelerator accelerates the graphic computation to make the rendering smooth and off-load CPU to save power consumption.

The open-source code environment provides the product development more flexibility. For reducing
system complexity while cutting the BOM cost, the N9H20 series provides MCP (Multi-Chip Package)
to ensure higher performance and to minimize the system design efforts. Total BOM cost could be cut
by employing 2-layer PCB along with the elimination of external parts, EMI prevention components and saving board design space.
