Signals/Connections
The DSP56303 input and output signals are organized into functional groups, as shown in Table
2-1 and illustrated in Figure 2-1. The DSP56303 operates from a 3 V supply; however, some of
the inputs can tolerate 5 V. A special notice for this feature is added to the signal descriptions of
those inputs.

Port A signals define the external memory interface port, including the external address bus, data bus, and
control signals.
Port B signals are the HI08 port signals multiplexed with the GPIO signals.
Port C and D signals are the two ESSI port signals multiplexed with the GPIO signals.
Port E signals are the SCI port signals multiplexed with the GPIO signals.
The number of Ground signals listed are for the 144-pin TQFP package. For the 196-ball MAP-BGA package,
there are 66 GND connections.
