Thermal Specifications
The 80960Jx is specified for operation when T
100° C for PGA, MPBGA and PQFP packages. Extended temperature devices are also available in
a PQFP package and an MPBGA package with T
measured in any environment to determine whether the 80960Jx is within its specified operating
range. The case temperature should be measured at the center of the top surface, opposite the pins.
