我们做的一块MPC5746C的片子,上电之后,复位脚一直是0V,复位脚没有对地短路,也有上拉电阻,芯片电源脚都是正常的。

这是什么问题呢,怎么解决呢?

Hi,

translated to English by google:

We made a piece of MPC5746C film, after power-on, the reset pin is always 0V, the reset pin is not shorted to the ground, there is also a pull-up resistor, the chip power supply pin is normal.

What is the problem? How to solve it?

Could you share with us the reset circuit schematics?

What is the value of Pull-up?

Are you talking about MPC5746R or B/C?

regards,

Peter
