MPC8245 Part Number Specification for the MPC8245ARZUnnnX Series, Rev. 2

Freescale Semiconductor
General Parameters
4.3.3
Output AC Timing Specification
Table 11
provides the processor bus AC timing specification for output hold time for debug signals in the 466-MHz
CPU of the MPC8245 at recommended operating conditions (see
Table 2
) with LV
DD
= 3.3 V ± 0.3 V. All output
timings assume a purely resistive 50-
load (see Figure 14 in the
MPC8245 Integrated Processor Hardware
Specifications
). Output timings are measured at the pin; time-of-flight delays must be added for trace lengths, vias,
and connectors in the system. These specifications are for the default driver strengths listed in the
MPC8245
Integrated Processor Hardware Specifications
.

Note:
1. All memory and related interface output signal specifications are specified from the VM = 1.4 V of the rising edge of the
memory bus clock, SDRAM_SYNC_IN to the TTL level (0.8 or 2.0 V) of the signal in question. SDRAM_SYNC_IN is
the same as PCI_SYNC_IN in 1:1 mode, but is twice the frequency in 2:1 mode (processor/memory bus clock rising
edges occur on every rising and falling edge of PCI_SYNC_IN).
