Documentation

Table 2 lists the documents that provide a complete description of the DSP56374 and are required to design

properly with the part. Documentation is available from a local Freescale Semiconductor, Inc. (formerly

Motorola) distributor, semiconductor sales office, Literature Distribution Center, or through the Freescale

DSP home page on the Internet (the source for the latest information).

Signal Groupings

The input and output signals of the DSP56374 are organized into functional groups, which are listed in

Table 3.

The DSP56374 is operated from a 1.25 V and 3.3 V supply; however, some of the inputs can tolerate 5.0 V.

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