NK-N9H30
1. Introduction
Nuvoton offers the emWin platform which is embedded with Nuvoton N9H MPU, it provides complete HMI solutions which are further enhanced by the emWin software. The N9H series with ARM926EJ-S core can operate at up to 300 MHz and can drive up to 1024x768 pixels in parallel port. It integrated TFT LCD controller and 2D graphics accelerator, up to 16 million colors (24-bit) LCD screen output, and provides high resolution and high chroma to deliver gorgeous display effects. To play compressed video in HMI screens smoothly, the N9H series is equipped with H.264 video decompression engine. It also offers built-in voice decoder, which can streamline the peripheral circuits of HMI applications with sound playback. It embedded up to 64 MB DDR memory, along with ample hardware storage and computing space for excellent design flexibility.
