Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I need a PIC with the following attributes.
One that I can write assembly programmes using MPLAB IDE. I don't have the time to learn the MPLAB Xpress.

A 40 pin DIP package that has at least 16 i/o with Interrupt on Change. (I need at least 28 i/o in total)
An internal oscillator would be ideal, but not essential. I can use a crystal if necessary.
The osc frequency is not critical. Anything from 32 kHz upwards.

I have searched the Microchip web site for a list of the attributes of the various PICs.
Such a list may exist, but I could not find anything useful.
Any assistance will be appreciated.

You might like something like a PIC18F45K22. However, the minimum 16 Interrupt on Change pins looks like a problem.

Use Microchip MAPS to find Microchip microcontrollers.
Visit Vegipete's *Mite Library for cool programs.
