I am replacing Infineon C167CR by ST10R167 in my application. The pin RPD for the Infineon device is not connected to 5V. For the ST10R167, an external RC is recommended. I don't use the power-down mode.

Can I connect pin 84 to ground?

Hello,

Given that you don't use interruptible power down mode, you can connect RPD pin to ground directly or via a resistor. But in this case, the length of the reset signal must be long enough to operate correctly (port 0 needs time to be sampled correctly). If the pulse is short, the clock may not have time to start and the microcontroller may lock in an undefined state(erroneous sampling of port0). I recommend something in the ms range(1ms and more). I hope this answers your question Refer to this link for more informations: http://www.stmcu.com/forums-cat-87-5.html Najoua [ This message was edited by: Najoua on 25-06-2004 16:43 ][ This message was edited by: Najoua on 25-06-2004 17:03 ]
