尽量朝“单片”方向设计硬件系统。系统器件越多，器件之间相互干扰也越强，功耗也增大，也不可避免地降低了系统的稳定性。随着单片机片内集成的功能越来越强，真正的片上系统SoC已经可以实现，如ST公司新近推出的μPSD32××系列产品在一块芯片上集成了80C32核、大容量FLASH存储器、SRAM、A/D、I/O、两个串口、看门狗、上电复位电路等等。 -North Korea as the "single-chip" design direction of the hardware system. System devices more mutual interference between devices are more strong, power consumption is increased, it will inevitably reduce system stability. With MCU with on-chip integration of more powerful, the real system-on-chip SoC can achieve, such as ST"s new PSD32 x x in a series chip integrates exertion nuclear, large-capacity flash memory, SRAM, A/D, I/O, 2 serial port, watchdog, the power-on reset circuit and so on.
