Notes:
1. All specified voltages are with respect to GND.
2. Empirical data indicates that all chip voltages should begin to ramp-up within 1 ms of each other. There should never be voltage present
at the I/O pins before OVDD is within operating range.
Package Thermal Specifications
The PPC405GPr is designed to operate within a case temperature range of -40°C to +85°C3. Thermal resistance values for the
E-PBGA packages (leaded and lead-free) in a convection environment are as follows:

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×θJC, where TJMax is maximum junction temperature and P is power consumption.
3. 333MHz operated at 266MHz or less can operate at +105°C.
