Voltage and Frequency Derating
To reduce the power consumption of the device, these devices support voltage and frequency derating
whereby the core voltage (VDD) may be reduced if the reduced maximum processor core frequency
requirements are observed. The supported derated core voltage, resulting maximum processor core
frequency (fcore), and power consumption are provided in Table 11. Only those parameters in Table 11 are
affected; all other parameter specifications are unaffected.
