2 Signal/Connection Descriptions

2.1 Signal Groupings

The input and output signals of the DSP56367 are organized into functional groups, which are listed in

Table 2-1 and illustrated in Figure 2-1.

The DSP56367 is operated from a 1.8V supply; however, some of the inputs can tolerate 3.3V. A special

notice for this feature is added to the signal descriptions of those inputs.

Remember, the DSP56367 offers 150 million instructions per second (MIPS) using an internal 150 MHz

clock at 1.8 V and 100 million instructions per second (MIPS) using an internal 100 MHz clock at 1.3.3V.

1 Port A is the external memory interface port, including the external address bus, data bus, and control signals.

2 Port B signals are the GPIO port signals which are multiplexed with the HDI08 signals.

3 Port C signals are the GPIO port signals which are multiplexed with the ESAI signals.

4 Port E signals are the GPIO port signals which are multiplexed with the ESAI_1 signals.

5 Port D signals are the GPIO port signals which are multiplexed with the DAX signals.
