Figure 41. Analysis Heat Sink Dimensions
Table 25 shows the T
A
required given a 29.2 W processor (150 MHz, 256K cache), and a T
C
of 85°C.. Table 26
shows the T
A
required assuming a 40W processor. Table 25 and Table 26 were produced by using the
relationships of Section 6.1.3. and the data of Table 24.
