Description: 我们对处理速度的需求日益增长，伴随着这种增长，用来构建单片机的晶体管尺寸则在持续减小。以更低的成本实现更高的集成度，也促进了对更小的几何尺寸的需求。随着尺寸的减小，晶体管击穿电压变得更低，最终，当击穿电压低于电源电压时，就要求减小电源电压。因此，随着速度的提高和复杂程度的上升，对于高密度器件而言，不可避免的后果就是电源电压将从5V降至3.3V，甚至1.8V。
Microchip 单片机的速度和复杂性已经到达足以要求降低电源电压的程度，并正在向5V 电源电压以下转换。但问题是绝大多数接口电路仍然是为5V电源而设计的。这就意味，作为设计人员，我们现在面临着连接3.3V和5V 系统的任务。此外，这个任务不仅包括逻辑电平转换，同时还包括为3.3V系统供电、转换模拟信号使之跨越3.3V/5V的障碍。-3V 5V system connection skill
