Power Dissipation
400 MHz

11.40 W
Notes:
1.
2. This specification applies to components using a CLK frequency of 66 MHz.
3. The active application power measurements were taken by running a suite of embedded benchmarks covering four major
embedded market segments: automotive, office automation, networking, and telecommunications.
4. 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-K6-2E+ processor.
5. Maximum power is determined for the worst-case instruction sequence or function for the listed clock control states with
V
CC2
= 2.0 V and V
CC3
= 3.3 V.
6. The CLK signal and the internal PLL are still running, but most internal clocking has stopped.
7.
The CLK signal, the internal PLL, and all internal clocking has stopped.
This specification applies to components using a CLK frequency of 100 MHz.

Notes:
1.
An x in this column represents the package type. See Table 79, “AMD-K6-2E+ Embedded Processor Valid Ordering Part Number Com-
binations,” on page 334.
2. AMD PowerNow! technology enables the operating frequency to step down in increments corresponding to the available bus frequency
multipliers. Note that 250-MHz operation is not supported due to exclusion of 2.5 bus frequency multiplier.
