'[PIC:] Which pic to use?'

Hi,
I'm making a really powerful scientific calculator and I need to know which
kind of PIC to use.
The program I'm writing is fairly big (a whole equation parser, lots of
other stuff) - maybe about 15 pages long and is in C.
The pic needs I2C for serial eeprom i/o, enough i/o for a small lcd and a
large matrix keypad which i think should'nt be an issue just fitting my code
in.
It also needs to be under $10.
Will my program fit on a Pic16xxx?

Thanks,
Arron

As a start look at Microchip's free tool called the PIC Calculator.  It lets you parametrically select devices by filtering out wanted or unwanted features.

Cheers,

How about you compile it and see how much code is emitted?
