Hey all, I think I found the perfect chip for my calculator project. It's a 16 bit PIC 24 HJ 128 GP 202 (or 502 with ECAN). 128K flash, 8K RAM, 28 pin SPDIP. Operates at 3.0 to 3.6 V. What I love about it is that the Microchip C30 compiler supports long doubles (64 bit) natively. I'm going to experiment with the compiler/simulator for this chip and take a look at this datasheet to make sure everything's the way I want it. I just hope it consumes very little power. Has anyone used this chip or similar chips? How are they?
