Most LCDs and other circuits will work fine with 3.3V. Some LCDs do get a
little slow so you need to acount for that.
The place you pay is in analog. A/D's don't work nearly as well at the
lower voltage. That is the only reason why they keep the 30F around.
By the way, if you want 5 volts, the 30F is practically the same chip. Of
course it has the DSP engine, but that is sort of an add on, and doesn't
change the was the basic chip works (darn cool add-on tho). It also has
EEPROM which is lacking in the 24F, and it has more capable A/D. But it is
lacking the ability to reassign pins which is a really cool feature of the
24, and it is quite a bit more power hungry.
Also keep in mind:
24F - 16 MIPS
30F - 30 MIPS
24H - 40 MIPS

Re: PIC24F - Paul Laverick - Apr 19 13:11:22 2009
I had a look into the 30F and got a little nervous, so was hoping to start on a simple 16
bit, but then again, if I'm only playing, then 3.3V is not a problem
The structure of the 30F seemed different to the 24F but i suppose i should look into it more.
I don't really think i need a 16 Bit chip, but i am keen to experiment
Cheers!
