13.3 OPERATING CONDITIONS

13.3.1 General Operating Conditions

Figure 51. fOSC Maximum Operating Frequency Versus VDD Supply Voltage for ROM devices

Figure 52. fOSC Maximum Operating Frequency Versus VDD Supply Voltage for FLASH devices

Notes:

1. Guaranteed by construction. A/D operation and resonator oscillator start-up are not guaranteed below 1MHz.

2. Operating conditions with TA=-40 to +125°C.

3. FLASH programming tested in production at maximum TA with two different conditions: VDD=5.5V, fCPU=8MHz and

VDD=3V, fCPU=4MHz.
