An effective system-level board design requires termination of specific pins and taking
advantage of idle and power-down modes on these low power
VC5503/5506/5507/5509A digital signal processors (DSPs). This can be achieved by
controlling unused pins and dynamically turning off all peripherals and internal
functional units when not in use. The benefit is that the DSP and application consume
only as much power as needed, which also helps reduce heat, component density, and
the cost of the product. This document also provides pointers to valuable information
about how to terminate some of the VC5503/5506/5507/5509A peripherals’ and core
DSPs unused pins.
