Electrical

Characteristics

Static Characteristics

Notes:

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

2. For processor bus signals, the reference is OV

DD while L2OVDD is the reference for the L2 bus signals.

3. Excludes factory test signals.

4. Capacitance is periodically sampled rather than 100% tested.

5. The leakage is measured for nominal OV

DD and L2OVDD, or both OVDD and L2OVDD must vary in the same direction (for

example, both OVDD and L2OVDD vary by either +5% or –5%).

6. Measured at max OVDD/L2OVDD

7. Excludes IEEE 1149.1 boundary scan (JTAG) signals.
