The 711 may be programmed as if it were a 16C621 with an older programmer. The EPROM space and config word have identical addressing. -Kurt ______________________________ Reply Separator _________________________________ Subject: RE : PIC16C71 vs PIC16C711 Author: Werner Terreblanche at Internet_Exchange Date: 12/3/96 5:14 PM Kerzer Computers wrote: > I need the hardware ( schematics ) and software to program these >things. Can someone help me please Sorry, but I can not directly help you. There are many people more qualified on this list to do so. However I also am sitting with a dilemma regarding PIC16C71 now. I'm using PIC16C71's in a Variometer product that I make for the paragliding fraternity. My dilemma is that I now want to start using the PIC16C711 which is essentially the same as the PIC16C71, but with brown-out protection built in. But when I phoned our local supplier they told me that the PIC16C711 opererates slightly different and that my current software may not work. What is worse, apparently some programmer hardware even have difficulty programming the PIC16C711! According to the spec sheets that I've just pulled from the Microchip Web site, the two look identical except for the brown-out protection that was added and its resultant control bit. Has anyone else on the list already made this transition from PIC16C71 to PIC16C711 and did you experience any problems as a result of this?
