• Manufacturer Part Number: MSC8103
• Description: Network Digital Signal Processor
• Manufacturer: Freescale Semiconductor / Motorola

Signals/Connections
The MSC8103 external signals are organized into functional groups, as shown in Table 1-1, Figure 1-1, and
Figure 1-2. Table 1-1 lists the functional groups, states the number of signal connections in each group, and
references the table that gives details on multiplexed signals within each group. Figure 1-1 shows MSC8103
external signals organized by function. Figure 1-2 indicates how the parallel input/output (I/O) ports signals are
multiplexed. Because the parallel I/O design supported by the MSC8103 communications processor module
(CPM) is a subset of the parallel I/O signals supported by the MPC8260 device, port pins are not numbered
sequentially.
