Table 69 and Figure 105 show the measured values for the case-
to-ambient thermal resistance (
levels of airflow in the system for the low-power embedded
AMD-K6-2E processors with a maximum thermal power
dissipation of 10.0 watts (OPNs: AMD-K6-2E/266AMZ,
AM D-K6 -2E/ 300 AMZ , and AMD - K6 -2 E/ 33 3A MZ) and a
maximum case temperature rating of 85
Ceramic Pin Grid Array package (CPGA) when installed into a
socket.
