Package Thermal Specifications

The 80960CF is specified for operation when TC

(case temperature) is within the range of 0°C–100°C

for 33, 25, and 16 MHz and 0 °C–85°C for 40 MHz.

TC may be measured in any environment to deter-

mine whether the 80960CF is within specified oper-

ating range. Case temperature should be measured

at the center of the top surface, opposite the pins.

Refer to Figure 5.

TA (ambient temperature) is calculated from θCA

(thermal resistance from case to ambient) using the

equation:

TA = TC – P*θCA

Table 9 shows the maximum TA allowable (without

exceeding TC) at various airflows and operating

frequencies (fPCLK).

Note that TA is greatly improved by attaching fins or

a heatsink to the package. P (maximum power

consumption) is calculated by using the typical ICC

as tabulated in Section 4.4, DC Specifications and

VCC of 5 V.
