The power supply of the device must start its ramp from 0.0 V.
Functional operating conditions are provided with the DC electrical specifications in Table 6-5. Absolute maximum
ratings are stress ratings only; functional operation at the maxima is not guaranteed. Stress beyond those listed may
affect device reliability or cause permanent damage to the device.
Caution : All inputs that tolerate 5 V cannot be more than 2.5 V greater than the supply voltage. This restriction applies
to power-up and normal operation (that is, if the MPC860 is unpowered, voltage greater than 2.5 V must not be
applied to its inputs).
Minimum temperatures are guaranteed as ambient temperature, T
junction temperature, T
Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site (board)
temperature, ambient temperature, air flow, power dissipation of other components on the board, and board thermal
resistance.
