Maximum Speed vs. V
AT90CAN32/64/128
Table 26-1.
Maximum frequency is depending on V
vs. V
given voltage in this interval, use this equation:
To calculate required voltage for a given frequency, use this equation:
Table 26-2.
At 3 Volt, this gives:
Thus, when V
At 8 MHz this gives:
Thus, a maximum frequency of 8 MHz requires V
