Maximum frequency is depending on V
Maximum Frequency vs. V
the maximum frequency at a given voltage in this interval, use this equation:
To calculate required voltage for a given frequency, use this equation::
Table 133. Constants used to calculate maximum speed vs. V
At 3 Volt, this gives:
Thus, when V
At 6 MHz this gives:
Thus, a maximum frequency of 6 MHz requires V
