I've looked at the 12F1501 in the past and it is indeed most of what=20 I mentioned above. However, it has the enhanced 16 register set of=20 32 RAM banks instead of all of the RAM being on a single RAM page. I can live with fewer peripherals (like what the 10F322 has) if it=20 has all RAM located on a single RAM page (like the 10F322). > > I'd be even happier if they released a 10-pin version with all 8 i/o > > pins made available . > >They already have, it's the 16F15xx series chips (there are about 4=20 >of them so far). OK - I'll go looking for them. I looked at the 16F1503 at the=20 beginning of this year but it is similar to the 16F676 in that it is=20 in a 14-pin package. And, like the 12F1501, it also has 32 RAM banks. >Not sure if the 1x15xx have a comparator. I haven't had occasion to=20 >look at that bit of the data sheet. The 12F1501 has a single comparitor, the 16F1503 has two. What I=20 really want, though, is a variant of the 10F322 in SOT23-6 package -=20 but with a comparitor added. Those I would use by the bushels-full. Also note that what I find so likeable about the 10F322 is that=20 single RAM page. 64 RAM locations for special-function registers and=20 64 bytes for user RAM. No RAM bank bits - not a single one. What's=20 not to like? . Don't get me wrong - I've been dealing with PICs for so long that=20 setting the appropriate RAM bank bits is like second nature to=20 me. And - Byron Jeff's help over the past day in dealing with more=20 RAM banks than the 4 that I'm currently used to means that I can do=20 all of the cool things I'm already used to doing with the=20 enhanced-core PICs. But from a newbie point of view, having NOT to=20 deal with RAM bank issues would be invaluable. dwayne --=20 Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
