MPC8241 Integrated Processor Hardware Specifications
MOTOROLA
System Design Information
vias to minimize inductance. Suggested bulk capacitors: 100–330 F (AVX TPS tantalum or Sanyo
OSCON).
1.7.4
Connection Recommendations
To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal
level. Unused active-low inputs should be tied to OVDD. Unused active-high inputs should be connected to
GND. All NC (no connect) signals must remain unconnected.
Power and ground connections must be made to all external VDD, GVDD_OVDD, LVDD, and GND pins of
the MPC8241.
The PCI_SYNC_OUT signal is intended to be routed halfway out to the PCI devices and then returned to
the PCI_SYNC_IN input of the MPC8241.
The SDRAM_SYNC_OUT signal is intended to be routed halfway out to the SDRAM devices and then
returned to the SDRAM_SYNC_IN input of the MPC8241. The trace length may be used to skew or adjust
the timing window as needed. See Motorola application notes AN1849/D, MPC107 Design Guide, and
AN2164/D, MPC8245/MPC8241 Memory Clock Design Guidelines, for more information on this topic.
Note that there is an SDRAM_SYNC_IN to PCI_SYNC_IN time requirement (see Table 10).
1.7.5
Pull-Up/Pull-Down Resistor Requirements
The data bus input receivers are normally turned off when no read operation is in progress; therefore, they
do not require pull-up resistors on the bus. The data bus signals are: MDH[0:31], MDL[0:31], and PAR[0:7].
If the 32-bit data bus mode is selected, the input receivers of the unused data and parity bits (MDL[0:31]
and PAR[4:7]) will be disabled, and their outputs will drive logic zeros when they would otherwise normally
be driven. For this mode, these pins do not require pull-up resistors and should be left unconnected by the
system to minimize possible output switching.
The TEST0 pin requires a pull-up resistor of 120
or less connected to GV
DD_OVDD.
It is recommended that RTC have weak pull-up resistors (2–10 k
) connected to GV
DD_OVDD.
It is recommended that the following signals be pulled up to GVDD_OVDD with weak pull-up resistors
(2–10 k
): SDA, SCL, SMI, SRESET/SDMA12, TBEN/SDMA13, CHKSTOP_IN/SDMA14,
TRIG_IN/RCS2, and DRDY.
It is recommended that the following PCI control signals be pulled up to LVDD with weak pull-up resistors
(2–10 k
): DEVSEL, FRAME, IRDY, LOCK, PERR, SERR, STOP, and TRDY. The resistor values may
need to be adjusted stronger to reduce induced noise on specific board designs.
The following pins have internal pull-up resistors enabled at all times: REQ[3:0], REQ4/DA4, TCK, TDI,
TMS, and TRST. See Table 17 for more information.
The following pins have internal pull-up resistors enabled only while device is in the reset state:
GNT4/DA5, MDL0, FOE, RCS0, SDRAS, SDCAS, CKE, AS, MCP, MAA[0:2], PMAA[0:2], and
QACK/DA0. See Table 17 for more information.
The following pins are reset configuration pins: GNT4/DA5, MDL[0], FOE, RCS0, CKE, AS, MCP,
QACK/DA0, MAA[0:2], PMAA[0:2], SDMA[1:0], MDH[16:31], and PLL_CFG[0:4]/DA[10:15]. These
pins are sampled during reset to configure the device. The PLL_CFG[0:4] signals are sampled a few clocks
after the negation of HRST_CPU and HRST_CTRL.
