Bus Signal Timing
This recommendation particularly applies to the address and data buses. Maximum PC trace lengths of 6” are
recommended. Capacitance calculations should consider all device loads as well as parasitic capacitances due to the
PC traces. Attention to proper PCB layout and bypassing becomes especially critical in systems with higher
capacitive loads because these loads create higher transient currents in the VDD and GND circuits. Pull up all unused
inputs or signals that will be inputs during reset. Special care should be taken to minimize the noise levels on the
PLL supply pins. For more information, please refer to Section 14.4.3, Clock Synthesizer Power (VDDSYN,
VSSSYN, VSSSYN1), in the MPC866 User’s Manual.
10 Bus Signal Timing
The maximum bus speed supported by the MPC866/859 is 66 MHz. Higher-speed parts must be operated in
half-speed bus mode (for example, an MPC866/859 used at 100 MHz must be configured for a 50-MHz bus).
Table 7 and Table 8 show the frequency ranges for standard part frequencies.
Table 9 shows the timings for the MPC866/859 at 33, 40, 50, and 66 MHz bus operation. The timing for the
MPC866/859 bus shown in this table assumes a 50-pF load for maximum delays and a 0-pF load for minimum
delays. CLKOUT assumes a 100-pF load maximum delay.
