Hey all,

I'm trying to build a scientific RPN calculator using a PIC microcontroller.
It will be battery powered and for use in school. I'll be using it with an
HD44780 based LCD character display and my own keypad.

Basically, I'll need enough flash and RAM on the PIC to store all the
functions a scientific calculator would have (sin, cos, tan, asin, acos,
atan, log, ln, ee, e^x, pow, sqrt and so on). As for the second requirement,
I'll need it to be as low power as possible as it will run on small
batteries.

Also, I'll be programming in C using HI-TECH's highly optimizing C compiler
for the PIC. This compiler is amazing.

I've already looked at the PIC 16F series. These seem to use low power but
I'm scared that they will not have enough flash (and possibly RAM) for my
application.
Then I looked at the 18F series. These also seem to be low power and have a
lot more RAM and flash.
I was then tempted by the PIC32 series. These chips look perfect for my
project. I'm now only concerned about the power usage of these things. Does
anyone know the power usage for the PIC32 series?

Anyway, I need advice. Which series of microcontroller should I chose for my
project?
