9.3 OPERATING CONDITIONS

9.3.1 General Operating Conditions

Figure 59. 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.

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

VDD=3V, fCPU=4MHz.
