self-programming Fuses from SW?
If you're willing to move on to the Xmega series of AVRs, then you'll find that most of the things which you'd normally use the fuses to configure, are now under direct software...

BIG BUG ON UC3A0512
For what it's worth, Atmel definitely isn't alone in silicon errata like this. For example, the NXP LPC111x family of ARM Cortex-M0 parts are documented to exhibit a similar...

ISR vector override
Perhaps the OP would like to pull in something like FreeRTOS to take care of the "run immediately" problem. I envision running the mainline code in a "low" priority thread, and...

WinAVR and tiny10
If you want a real C compiler for the ATtiny10, currently your only viable options may be the proprietary compilers. Both IAR and CodeVision list support for the ATtiny10 and its...

How to access the external RAM which address is beyond 64K
Another option: If you opt for the IAR C compiler, then you'll have built-in support for all the various memory models, including the ability to apply "tiny", "near", "far", and "...

External clock maximum frequency
Was your boss's concern about error percentages due to the inherent uncertainty in the 32 MHz oscillator's actual frequency? Or was it due to the mathematical inability to divide...
