Notes:

1. Nominal voltages; see Table 4 for recommended operating conditions.

2. For processor bus signals, the reference is OVDD while GVDD is the reference for the L3 bus signals.

3. Excludes test signals 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/GVDD and VDD, or both OVDD/GVDD and VDD must vary in the same

direction (for example, both OVDD and VDD vary by either +5% or –5%).

6. Applicable to L3 bus interface only.
