18F4X2 OSC pins datasheet error
PostPosted: Wed Aug 04, 2004 7:10 am     Reply with quote
Sorry, this is a hardware question.

I'm considering using the QFN package of the 18F452. The only place the pinout is listed is in the Silicon Eratta sheet http://ww1.microchip.com/downloads/en/DeviceDoc/80173a.pdf

The pinout diagram shows OSC2 on pin 33, and OSC1 on pin 32. However the pinout table states pin 32 is NC, OSC1 on pin 33, and OSC2 isn't even assigned to a pin!

I tend to believe the pinout diagram, and looks like the table has a typo - am I missing something?

I would email Microchip Technical support with your question and point out the confusion. That's probably the safest way to ensure that you have the correct pinouts.

Thanks, I emailed Microchip Tech support and received the following reply:

Hi Patrick,

The pinout diagram is correct. We are in process of modifying the errata document to correct the table. The pin numbers has been shifted by one row in table.

Regards,

Gaurang.
