Notes:
1. Nominal voltages; see Table 3 for recommended operating conditions.
2. For processor bus signals, the reference is OVDD while L2OVDD 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 OVDD and VDD, or both OVDD and VDD must vary in the same direction (for
example, both OVDD and VDD 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 (OVDD
and L2OVDD) or PLL/DLL supply power (AVDD and L2AVDD). 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 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 VDD (see Table 3) and 65°C in a system
while running a typical code sequence.
4. Not 100% tested. Characterized and periodically sampled.
