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.

Do you need all 16 i/o pins as Interrupt on Change? or 3 to 4 pins are enough as Interrupt on Change?
 

Yes, I need 16. There are plenty of PICs such as the 16F877 that have 4 IOC pins.

Hi,

The latest PIC16F1xxxx have IOC almost on each pin ;=)
e.g. the PIC16F18877, the big big brother of the venerable PIC16F877A
Additionally, I suggest you use MCC plugin in MPLAB X to generate code as these new PICs have lots of new registers ;=)

Regards
