PC7447A
6.4.4.6
Minimum Core Frequency Requirements with DFS
In many systems, enabling DFS can result in very low processor core frequencies. However, care must
be taken to ensure that the resulting processor core frequency is within the limits specified in Table 9-2
on page 25. Proper operation of the device is not guaranteed at core frequencies below the specified
minimum f
core.
6.4.5
Power Consumption
Table 6-6 provides the power consumption for the PC7447A. For information regarding power consump-
tion when dynamic frequency switching is enabled, See “Dynamic Frequency Switching (DFS)” on page
Notes:
1. These values apply for all valid processor buses. The values do not include I/O supply power (OVDD) or PLL supply power
(AVDD). OVDD power is system dependent but is typically < 5% of VDD power. Worst case power consumption for AVDD <
3mW.
2. Typical power is an average value measured at the nominal recommended V
DD (see Table 6-2 on page 10) and 65°C while
running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz
3. Maximum power is the average measured at nominal V
DD and maximum operating junction temperature (see Table 6-2 on
page 10) while running an entirely cache-resident, contrived sequence of instructions which keep all the execution units
maximally busy.
4. Doze mode is not a user-definable state; it is an intermediate state between full-power and either nap or sleep mode. As a
result, power consumption for this mode is not tested.
5. Power consumption for these devices is artificially constrained during screening to assure lower power consumption than
other speed grades.
