Recommendation for 14 pin DIP PIC

I'm about to start work on a really simple project- I need to make a replacement for the mechanical timer in an electric clothes dryer. It's going to be a simple state machine, so it doesn't need much memory or a lot of peripherals. Microchip's MAPS hasn't been much help. I need a recommendation for a PIC that meets the following requirements:
8 bit PIC family
Supported by the compiler
Low cost
5 volt Vcc
Prefer 14-pin DIP package (but could go to 16 pin or even 18 if necessary).  It does need to be DIP, though
Prefer a chip that allows access to the port latches (to avoid the read-modify-write problem)
Prefer a chip that does NOT have peripheral pin select (but it's not a deal-breaker if it does have it)

Would someone be kind enough to point me to a chip that meets the requirements?

Thanks!

Hi rick,

besides MAPS I also look at Digikey - they have much better filters and at the same time you can check what is available.

Check this selection table.

Thank you!! I use Digikey all the time for selecting all sorts of components, but I must have been having a senior moment and I just didn't think to search there. It looks like the winner is PIC16F1503.  I'll get some on the way!

Thanks for the help!

Rick, in what way can Microchip MAPS not help you?

Edit: I assume because (as I see now) a selection for the package type (DIP, SOIC, etc.) is missing.

The newer 18F devices are really good, and come in 14-pin packages.

For example, the 18F06Q20 and 18F06Q41 devices are really nice, and I've worked with them myself lately.

Also... Because they are relatively new devices, they are the least expensive. But if a simple application is required, maybe look at the enhanced 14-bit core types.
