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 (OV
DD
and L2OV
DD
) or PLL/DLL supply power (AV
DD
and
L2AV
DD
). OV
DD
and L2OV
DD
power is system dependent, but is typically < 10% of
V
DD
power. Worst case power consumption for AV
DD
= 15 mW and L2AV
DD
= 15 mW.
2. Maximum power is measured at nominal V
DD
(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 V
DD
(see Table 5) and 65×C in a system while running a typical code sequence.
4. Not 100% tested. Characterized and periodically sampled.
