Notes:
1.
OVDD supplies power to the processor bus, JTAG, and all control signals; and VDD supplies power to the
processor core and the PLL (after filtering to become AVDD). To program the I/O voltage, connect BVSEL to
either GND (selects 1.8 V) or to HRESET (selects 2.5 V). If used, the pulldown resistor should be less than
250
. For actual recommended value of V
in or supply voltages see Table 4.
2.
These input signals are for factory use only and must be pulled up to OVDD for normal machine operation.
3.
These signals are for factory use only and must be left unconnected for normal machine operation.
4.
Ignored in 60x bus mode.
5.
This signal selects between MPX bus mode (asserted) and 60x bus mode (negated) and will be sampled at
HRESET going high.
6.
This signal must be negated during reset, by pull-up to OVDD or negation by HRESET (inverse of HRESET), to
ensure proper operation.
7.
Internal pull-up on die.
8.
These pins require weak pull-up resistors (for example, 4.7 k
) to maintain the control signals in the negated
state after they have been actively negated and released by the MPC7445 and other bus masters.
9.
These input signals are for factory use only and must be pulled down to GND for normal machine operation.
10. This pin can externally cause a performance monitor event. Counting of the event is enabled via software.
11. Unused address pins must be pulled down to GND.
12. This test signal is recommended to be tied to HRESET; however, other configurations will not adversely affect
performance.
13. These signals must be pulled down to GND if unused, or if the MPC7445 is in 60x bus mode.
14. This signal must be asserted during reset, by pull-down to GND or assertion by HRESET, to ensure proper
operation.
