Introduced is the characteristic of mixed-signal system-on-one-board MCUs C8051F060 in this paper. Designed is a new ultra sonic imaging tool that its main control chip is C8051F060. Extended are the periphery circuits of single chip, such as, ultra sonic transmitting circuit, sonic transmitting range control circuit, echo pretreatment circuit, programme control amplifier circuit, peak value holder circuit, echo time inspection circuit, line synchronization signal-pick circuit, command receiving circuit and PCM code composed driver circuit. Each circuit works harmoniously by the single chip control, and completes sonic transmitting, receiving, processing and submission tasks, etc. The new design can effectively improve diagnostic accuracy and sensitivity of this tool. It has acquired a better application results in casing examination.
