Freescale Semiconductor MPC8260 - Manual (Page 108)

Overview
MPC8260 PowerQUICC II Family Reference Manual, Rev. 2
1-14 Freescale Semiconductor
Table 1-3 shows serial performance for the MPC8250, which does not support ATM (155-Mbps).
FCCs can also be used to run slower HDLC or 10 BaseT, for example. The CP’s RISC architecture has the
advantage of using common hardware resources for all FCCs.
1.7 Application Examples
The PowerQUICC II can be configured to meet many system application needs, as described in the
following sections and shown in
Figure 1-3 through Figure 1-11 .
NOTE: Differences between PowerQUICC II Devices
