Signal Listings
Note:
1. Multi-pin signals such as D1_MDQ[0:63] and D2_MDQ[0:63] have their physical package pin numbers listed in order
corresponding to the signal names.
2. Stub Series Terminated Logic (SSTL-18 and SSTL-25) type pins.
3. If a DDR port is not used, it is possible to leave the related power supply (Dn_GVDD, Dn_MVREF) turned off at reset. Note
that these power supplies can only be powered up again at reset for functionality to occur on the DDR port.
4. Low Voltage Differential Signaling (LVDS) type pins.
5. Low Voltage Transistor-Transistor Logic (LVTTL) type pins.
6. This pin is a reset configuration pin and appears again in the Reset Configuration Signals section of this table. See the Reset
Configuration Signals section of this table for config name and connection details.
7. Recommend a weak pull-up resistor (1–10 k
Ω) be placed from this pin to its power supply.
8. Recommend a weak pull-down resistor (2–10 k
Ω) be placed from this pin to ground.
9. This multiplexed pin has input status in one mode and output in another
10. This pin is a multiplexed signal for different functional blocks and appears more than once in this table.
11. This pin is open drain signal.
12. Functional only on the MPC8641D.
13. These pins should be left floating.
14. These pins should be connected to SVDD.
15. These pins should be pulled to ground with a strong resistor (270-
Ω to 330-Ω).
16. These pins should be connected to OVDD.
17.This is a SerDes PLL/DLL digital test signal and is only for factory use.
18. This is a SerDes PLL/DLL analog test signal and is only for factory use.
19. This pin should be pulled to ground with a 100-
Ω resistor.
