Notes:

1. The maximum power dissipated in the normal clock control state must be taken into account when designing a

solution for thermal dissipation for the AMD-K6 processor.

2. Maximum power is determined for the worst-case instruction sequence or function for the listed clock control states

with VCC2 = 2.9 V (for the 2.9 V component) or VCC2 = 3.2 V (for the 3.2 V component), and VCC3 = 3.3 V.

3. Typical power is determined for the typical instruction sequences or functions associated with normal system

operation with VCC2 = 2.9 V (for the 2.9 V component) or VCC2 = 3.2 V (for the 3.2 V component), and VCC3 = 3.3 V.

4. The CLK signal and the internal PLL are still running but most internal clocking has stopped.

5. The CLK signal, the internal PLL, and all internal clocking has stopped.
