Hello,I am using attiny84a mcu.
-I want to using internal rc oscillator.I haven't done any calibration with oscal register.So,How many volts at least can I use Vcc? 2.7volts or 3 volts?
-What happens if I use 1.8 volts?My crystal speed drops?
I studied the datasheet but I could not fully understand it.
Note:Slight variations in the 8 mhz crystal speed are not important to me.for example it can be 7.9 mhz,7.5mhz.If so, how many mhz would the speed drop?
Complete datasheet is here :http://ww1.microchip.com/downloads/en/DeviceDoc/doc8183.pdf
