Power consumption on the C6748/46/42 device is highly application-dependent, so a spreadsheet is provided to model power consumption for a user's application. To obtain good results from the spreadsheet, realistic usage parameters must be entered. The low-core voltage and other power design optimizations allow these devices to operate with industry-leading performance, while maintaining a low power-to-performance ratio.

The data presented in the accompanying spreadsheet was measured from strong units, representative of devices at the maximum end of power consumption for production units. No production units 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. The power data presented in this document are based on measured data with C6748 silicon revision 2.0 or earlier devices.

Although this spreadsheet was developed for the C6748 devices, it can be used to model power consumption for C6746 and C6742. Features not supported on these devices should not be enabled in the spreadsheet.
