Advance Information Datasheet

Package Thermal Specifications

The 80960Hx is specified for operation when TC (case temperature) is within the range of

0°C–85°C. TC may be measured in any environment to determine whether the 80960Hx is within

the specified operating range. Measure the case temperature 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 12 shows the maximum TA allowable (without exceeding TC) at various airflows and

operating frequencies (fCLKIN).

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 4.6, “DC

Specifications” on page 32 and VCC of 3.3 V.
