• Manufacturer Part Number: MPC8260A
• Description: Micro Processor
• Manufacturer: Motorola

Electrical and Thermal Characteristics
Table 9 lists CPM output characteristics.
Table 10 lists CPM input characteristics.
Note that although the specifications generally reference the rising edge of the clock, the following AC
timing diagrams also apply when the falling edge is the active edge.
Figure 2 shows the FCC external clock.
