AVR 12Mhz with VCC 3V?

If you stick with the words of the data sheet, yes, then this is overclocking.

There are AVRs with a more precise specification of supply voltage vs. allowed clock (in a diagram). Since the rating is consistent with the values given in other AVR data sheets, we assume that the other AVRs have a similar characteristics. See, for instance, the ATMega88 data sheet on page 302, section "Maximum Speed vs. VCC".

AVR 12Mhz with VCC 3V?

2007-09-29T17:49:33+02:00

Just wondering. The basic design shows the tiny2313 (or other AVRs) with 12Mhz clock at VCC 3.3V. But (all known) datasheets only permits clock frequencies >10Mhz only to VCC from 4.5 to 5.5V.
When i use the lower rate at 3v, is this an supported "overclocking" of the MCU?
