Design Support


This application report discusses the power consumption of the Texas Instruments TMS320TCI6482 digital signal processor (DSP). The power consumption on the TCI6482 device is highly application-dependent; therefore, a power spreadsheet that predicts power consumption is provided along with this document. The power spreadsheet can be used for the purpose of modeling power consumption for user applications such as power supply design, thermal design, etc. To get good results from the spreadsheet, realistic usage parameters must be entered, see Section 3.1. The low-core voltage and other power design optimizations allow these devices to operate with industry-leading performance, while maintaining a low powerto-performance ratio.

The data presented in this application report and accompanying spreadsheet was measured from devices at the maximum end of the power consumption for production devices. No production devices will have average power consumption that exceeds the spreadsheet values; therefore, the spreadsheet values may be used for board thermal analysis and power supply design as a maximum long-term average.
