Notes:
1. For a chip mounted on a JEDEC 2S2P card without a heat sink.
2. For a chip mounted on a card with at least one signal and two power planes, the following relationships exist:
a. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board.
b. TA = TC – P×θCA, where TA is ambient temperature and P is power consumption.
c. TCMax = TJMax – P
×θ
JC, where TJMax is maximum junction temperature and P is power consumption.
Absolute Maximum Ratings
The absolute maximum ratings below are stress ratings only. Operation at or beyond these maximum ratings can cause
permanent damage to the device

Notes:
1. If OVDD ≥ 0.4V it is required that VDD ≥ 0.4V. Supply excursions not meeting this criteria must be limited to less than 25ms dura-
tion during each power up or power down event.
Package Thermal Specications
The PPC405GP is designed to operate within a case temperature range of -40C to 120C. Thermal resistance values for
the E-PBGA packages in a convection environment are as follows:
