Operating Conditions
This section shows voltage, frequency, and temperature specifications for the processor for four
different ranges (shown in
Table 9, “Voltage, Temperature, and Frequency Electrical
Specifications”
.) The temperature specification for each range is constant; the frequency range
depends on the operation voltage.
Note:
The parameters in
Table 9
are preliminary and subject to change.
