Package and Pinout
Table 79 provides the pin-out listing for the MPC8567E 1023 FC-PBGA package.
30. This pin requires an external 4.7-k
Ω pull-down resistor to prevent PHY from seeing a valid Transmit Enable before it is actively
driven.
33. PF[21:22] are multiplexed as cfg_dram_type[0:1]. THEY MUST BE VALID AT POWER-UP, EVEN BEFORE HRESET
ASSERTION.
35. When a PCI block is disabled, either the POR config pin that selects between internal and external arbiter must be pulled
down to select external arbiter if there is any other PCI device connected on the PCI bus, or leave the PCIn_AD pins as "No
Connect" or terminated through 2–10 K
Ω pull-up resistors with the default of internal arbiter if the PCIn_AD pins are not
connected to any other PCI device. The PCI block will drive the PCIn_AD pins if it is configured to be the PCI arbiter—through
POR config pins—irrespective of whether it is disabled via the DEVDISR register or not. It may cause contention if there is any
other PCI device connected on the bus.
36.MDIC[0] is grounded through an 18.2-
Ω precision 1% resistor and MDIC[1] is connected to GVDD through an 18.2-Ω precision
1% resistor. These pins are used for automatic calibration of the DDR IOs.
39. If PCI is configured as PCI asynchronous mode, a valid clock must be provided on pin PCI_CLK . Otherwise the processor
will not boot up.
41.These pins should be tied to SCOREGND through a 300 ohm resistor if the high speed interface is used.
43. It is highly recommended that unused SD_RX/SD_RX lanes should be powered down with lane_x_pd. Otherwise the
receivers will burn extra power and the internal circuitry may develop long term reliability problems.
46. Must be high during HRESET. It is recommended to leave the pin open during HRESET since it has internal pullup resistor.
47. Must be pulled down with 4.7-k
Ω resistor.
48. This pin must be left no connect.
49. A pull-up on LGPL4 is required for systems that boot from local bus (GPCM)-controlled NOR Flash.
