Notes:
1. These values specify the power consumption for the core power supply (VDD) at nominal voltage and apply to all valid
processor bus frequencies and configurations. 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 <13mW.
2. Typical nominal power consumption is an average value measured at the nominal recommended VDD (see Table 4) and
65
°C while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz. This parameter is not 100%
tested but periodically sampled.
3. Maximum power consumption is the average measured at nominal VDD and maximum operating junction temperature (see
Table 4) while running an entirely cache-resident, contrived sequence of instructions to 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. Typical thermal power consumption is an average value measured at the nominal recommended VDD (see Table 4) and
105
°C while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz. This parameter is not 100%
tested but periodically sampled.
6. Typical power consumption for these modes is measured at the nominal recommended VDD (see Table 4) and 105°C in the
mode described. This parameter is not 100% tested but is periodically sampled.
7. Power consumption for the 1267 MHz device is intentionally constrained via testing and sorting to assure low power
consumption for this device.
