328P sleep current wildly different between two copies
With a small modification to avrdude.conf, you can read the extended signature bytes with a programmer; no need to compile & download code to the target. http://nerdralph....

has anyone analyzed ICSP in detail?
Here's the results of my testing.   Those results lead to some unresolved questions: 1) Why does Atmel recommend a 20ms delay before...

flashing AVRs at high speed
I finished a couple tests baking the t88 at 150C for 12 hours, with no measurable impact on retention.  I've updated my blog post with the details.

RC oscillator stability
I just tested the t84a, and it's even better than I expected.  As per the datasheet, it has a continuous and smooth OSCCAL curve.  The stability is so much better that I...
