The only local store to carry PIC stuff (Active Electronics, the retail division of Future Electronics) here in Ottawa carries a 16F877-04. This implies a 4 mHz part. The Microchip site doesn't even mention a 4 mHz chip - only 20 mHz. The Digi-Key catalog shows both 4 mHz and 20 mHz versions, so I guess there must be such a version. Does the -04 really mean a 4 mHz part? Larry Larry Bradley Orleans (Ottawa), Ontario, CANADA -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
