# Can I download a new program to a Silicon Labs C8051F311 with a JTAG programmer?

Or does that chip require a bunch of weird voltages that can only be generated by a "special" expensive device programmer?

 Just out of curiosity, why is this community wiki? – Kevin Vermeer Aug 13 '10 at 15:39 I understand what "wiki" means on other web sites -- it means other people can fix-up my all too frequent typos, making me look smart. The chiphacker FAQ implies it means the same thing here. If it means something different on Stack Exchange web sites, could you give me a link to the explanation? – davidcary Aug 13 '10 at 16:33 Here, wiki means that nobody gets any points. It's used for questions that might have multiple correct answers or provoke discussion. This question probably shouldn't be a wiki. – Toby Jaffey Aug 13 '10 at 16:35

Here's one, it's $35. -  Perfect. That's exactly what I wanted to know, and I like the way you pre-emptively answered what would have been my next question. – davidcary Aug 13 '10 at 15:54 35$ is too much. – sandun dhammika Apr 19 '12 at 19:15 @sandundhammika Then build your own from a cheap microcontroller or IO interface on a PC. The protocol seems to be documented. – Toby Jaffey Apr 19 '12 at 21:13
