Signals/Connections
1
The DSP56301 input and output signals are organized into functional groups, as shown in Table 1-1 and illustrated
in Figure 1-1. The DSP56301 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.
Table 1-1.

Notes:
1.
The number of available power and ground signals is package-dependent. In the TQFP package specific pins are dedicated
internally to device subsystems. In the MAP-BGA package, power and ground connections (except those providing PLL
power) connect to internal power and ground planes, respectively.
2.
Port A signals define the external memory interface port, including the external address bus, data bus, and control signals.
3.
Port B signals are the HI32 port signals multiplexed with the GPIO signals.
4.
Port C and D signals are the two ESSI port signals multiplexed with the GPIO signals.
5.
Port E signals are the SCI port signals multiplexed with the GPIO signals.
6.
Each device also includes several no connect (NC) pins. The number of NC connections is package-dependent: the TQFP
has 9 NCs and the MAP-BGA has 20 NCs. Do not connect any line, component, trace, or via to these pins. See Chapter 3
for details.
