Power Dissipation

Notes:

1. These values apply for all valid processor bus and L2 bus ratios. The values do not

include I/O supply power (OVDD and L2OVDD) or PLL/DLL supply power (AVDD and

L2AV

DD). OVDD and L2OVDD power is system dependent, but is typically < 10% of

VDD power. Worst case power consumption for AVDD = 15 mW and L2AVDD = 15 mW.

2. Maximum power is measured at nominal VDD (see Table 5) while running an entirely

cache-resident, contrived sequence of instructions which keep the execution units

maximally busy.

3. Typical power is an average value measured at the nominal recommended VDD

(see Table 5) and 65×C in a system while running a typical code sequence.

4. Not 100% tested. Characterized and periodically sampled.
