单片机复位电路可靠性的研究

Research of the credibility of the reset electric circuit on MCU

归纳了目前使用比较广泛的三种单片机复位电路,为微分型、积分型复位电路建立了数学模型,并比较了它们在使用中的可靠性,同时介绍了专用复位芯片。最后提出了设计复位电路应注意的问题及提高抗干扰性的措施。

Induced to use three kinds of machines to reset electric circuit currently, reset electric circuit to build up mathematics model for the differential calculus type,the integral calculus type, and compared them in the credibility in the usage, introduced appropriation to reset chip in the meantime.Put forward a design to reset the problem that the electric circuit should notice and raises anti-interference measure finally.
