PPC405EP – PowerPC 405EP Embedded Processor  
Data Sheet  
Table 6. Signal Functional Description (Sheet 6 of 6)  
Secondary multiplexed signals are shown in brackets.  
Notes:  
1. Receiver input has hysteresis.  
2. Must pull up. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.  
3. Must pull down. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.  
4. If not used, must pull up.  
5. If not used, must pull down.  
6. Strapping input during reset; pull up or pull down as required.  
7. Pull-up may be required. See “External Bus Control Signals” on page 30.

Table 7. 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. None of the performance specification contained in this document are guaranteed when  
operating at these maximum ratings.

Note:  
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.
