Overview
MPC8280 PowerQUICC II Family Reference Manual, Rev. 1
1-14
Freescale Semiconductor
The MPC8280 memory controller supports many types of memories, including EDO DRAM and
page-mode, pipeline SDRAM for efficient burst transfers.
1.7.1.2
Regional Office Router
Figure 1-4 shows a regional office router configuration.
Figure 1-4. Regional Office Router Configuration
In this application, the MPC8280 is connected to four TDM interfaces channelizing up to 128 channels.
Each TDM port supports 32–128 channels. If 128 channels are needed, each TDM port can be configured
to support 32 channels. This example has two MII ports for 10/100 BaseT LAN connections. In all the
examples, the SCC ports can be used for management.
1.7.1.3
LAN-to-WAN Bridge Router
Figure 1-5 shows a LAN-to-WAN router configuration, which is similar to the previous example.
