介    绍 三星的S3C44B0X 16/32位RISC处理器被设计来为手持设备等提供一个低成本高性能的方案。 S3C44B0X提供以下配置：2.5V ARM7TDMI 内核带有8Kcache ;可选的internal SRAM;LCD Controller(最大支持256色STN，使用LCD专用DMA)；2-ch UART with handshake(IrDA1.0, 16-byte FIFO) / 1-ch SIO； 2-ch gener

IGBTs were first introduced as a combination of the bipolar junction transistor (BJT) and the metal oxide semiconductor field effect transistor (MOSFET) technology. The IGBT is to prefer in medium high voltage segments (600- 3000V) rather than
