> Did you notice these are midrange, not baseline like the 10F2xx? > Microchips's naming conventions are a mystery to me.... 10F means 6-pin chip (the 8=3D-pin chip has 2 nc pins). The naming convention is very clear, but almost useless: 10F =3D 6 pins 12F =3D 8 pins 16F =3D >8 pins, 12 or 14 bit core 18F =3D 16 bit core There are no 16 bit core <=3D 8 pin chips yet, so I dunno whether a 6-pin=20 16-bit core chip would be a 10F or an 18F. --=20 Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: www.voti.nl/hvu --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
