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
