Typical practice where I work is to connect MCLR to Vdd, using the shortest path possible. Most of our designs use the 16C5x processors, without internal brownout circuits. You might wish to add an external power supply brownout shutdown to ensure that the processor resets properly after a temporary power down condition. ______________________________ Reply Separator _________________________________ Subject: Typical MLCR connection? Author: kevin.russell@NULL.NET at internet Date: 1/27/97 12:45 AM I am using some of the new PICS with brown out protection and want to know if I can just tie MCLR high? I think I have seen some designs with a resistor to prevent latch up? I would be interested in hearing what people typically do... Kevin Russell kevin.russell@null.net
