Yes, I know that. I was just responding to your comments about pads on the PCB for ICP. If a LPC903 could be programmed ICP with just pads and no jumpers, and then work by talking to a host PC through the UART and USB virtual serial port chip, that could work.
But the question in my original post was, "Why can't you just put some chips on a board, plug in to the USB, and ISP a chip". I guess this is not commonly done. I thought that someone would answer by saying LPC9xx, where xx is the simplest one that can do ISP, but you were also telling me the dangers of ["suicide" on a soldered-down LPC9xx] so I guess it is not a good idea. I build in low production quantities, so I do not differentiate between "production programming" and "field updates". |

What micro would you use? | 01/01/70 00:00 | |
LPC9xx | 01/01/70 00:00 | |
that would be a good option... | 01/01/70 00:00 | |
how do they use them then? | 01/01/70 00:00 | |
I don't use them... | 01/01/70 00:00 | |
I was just asking if someone would use that | 01/01/70 00:00 | |
We are talking about devboards, do we? | 01/01/70 00:00 | |
"slightly less than mass" | 01/01/70 00:00 | |
UART-ISP is not an option... | 01/01/70 00:00 | |
yes I know | 01/01/70 00:00 | |

no one | 01/01/70 00:00 | |
Perfect??? | 01/01/70 00:00 | |
You missed one... | 01/01/70 00:00 | |
Oh goodness, yes! That's very important ... | 01/01/70 00:00 | |
Depends upon the required functionality .. | 01/01/70 00:00 | |
Cygnal TQFP package , I would avoide any | 01/01/70 00:00 | |
why? | 01/01/70 00:00 | |
You can | 01/01/70 00:00 | |
