8.2 RECOMMENDED OPERATING CONDITIONS

Figure 58. fOSC Maximum Operating Frequency Versus VDD Supply Voltage

Notes:

1) Unless otherwise specified, typical data are based on TA=25°C and VDD-VSS=5V. They are given only as design guide-

lines and are not tested.

2) A/D operation and resonator oscillator start-up are not guaranteed below 1MHz.

3) Operating conditions TA=-40 to +85°C. The shaded area is outside the recommended operating range; device func-

tionality is not guaranteed under these conditions.
