MPC8280 PowerQUICC II™ Family Hardware Specifications, Rev. 1.7

Freescale Semiconductor

AC Electrical Characteristics

Table 12 lists SIU output characteristics.

NOTE

Activating data pipelining (setting BRx[DR] in the memory controller) improves

the AC timing.

Table 12. AC Characteristics for SIU Outputs 1

Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal.

Timings are measured at the pin.
