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.

Notes: 1.

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.
