NUVOTON N9H20K31N

The N9H20 series is built on the ARM926EJ-S, 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 ation 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.
