 		 #108267 - or - even better?
Responding to: ???'s previous message
use a SILabs f12x - f13x it has 8k RAM and 128k flash and 8 ports

since that amount of memory should, by far, be enough for your app, you will have 64 port pins to "play with"

the max port capability is 100mA per pin, 800mA total.
