和许多高度集成的IC一样，这种结构限制最大电源电压低于5V值LPC900系列被指定为在2.4V至3.6V工作。虽然电源电压低，在I / O引脚5V容限。Introduction
INTEGRATED CIRCUITS
ABSTRACT
To be able to offer the LPC900 family of microcontrollers with so
many on-chip features at low prices, they are made in a process,
which allows only 3V operation. This application note describes how
these microcontrollers can be adapted to 5V-systems.
