TMS320C672x Power Consumption Summary (Rev. B)

This document discusses the power consumption of the Texas Instruments TMS320C672x digital signal processor (DSP). Power consumption on TMS320C67x™ devices is highly application-dependent. A spreadsheet is provided to model power consumption for the user’s application. To get good results from the spreadsheet, realistic usage parameters must be entered. The low-core voltage and other power design optimizations allow these DSPs to operate with industry-leading performance,while maintaining a low power-to-performance ratio. The data presented in this document and in the accompanying spreadsheet was measured from units at the maximum end of power consumption for production units; no production units will have average power consumption that exceeds the spreadsheet values. Thus, the spreadsheet values may be used for board thermal analysis and power supply design as a maximum long-term average. All power measurements were taken from silicon revision 1.0 units of the TMS320C672x.
