Maximum Ambient
Temperature
Table 70 and Figure 106 show the measured maximum ambient
temperature (T_A) values in °C at different 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 (for
OPNs: AMD-K6-2E/266AMZ, AMD-K6-2E/300AMZ, and
AMD-K6-2E/333AMZ) and a maximum case temperature rating
of 85 °C, in the 321-pin Ceramic Pin Grid Array package (CPGA)
when installed into a socket.
