Keyboard display program writing MCU (Microcontrollers) is an integrated circuit chip is the use of large scale integrated circuit technology to a data processing capability of CPU CPU, RAM ram, Rom ROM, a variety of I/O port and interrupt system, timer / counter function (may also include a display drive circuit, pulse width modulation circuitanalog multiplexer the A/D converter circuit) integrated into a small and complete micro computer system composed of a piece of silicon, widely used in the field of industrial control. From the 80s of last century, the 4 - bit and 8 - bit singlechip developed to the present high speed MCU of 300M.
