Board and System Design Considerations for the TMS320VC5503/06/07/09A DSPs


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.
