Notes:
1. Nominal voltages; see
Table 3
for recommended operating conditions.
2. For processor bus signals, the reference is OV
DD
while L2OV
DD
is the reference for the L2 bus signals.
3. Excludes test signals (LSSD_MODE, L1_TSTCLK, L2_TSTCLK) and IEEE 1149.1 boundary scan (JTAG) signals.
4. Capacitance is periodically sampled rather than 100% tested.
5. The leakage is measured for nominal OV
DD
and V
DD
, or both OV
DD
and V
DD
must vary in the same direction (for example, both OV
DD
and
V
DD
vary by either +5% or –5%).

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 3
) 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 3
) and 65
°
C in a system while running a typical
code sequence.
4. Not 100% tested. Characterized and periodically sampled.
