AM335x Power Consumption Summary

Overview

CAUTION Data presented in this wiki was collected on an unsupported version of the SDK, and is provided for legacy purposes. For most recent data, please refer to the TI Processor SDK Kernel Performance Guide, Power Management section

Note: the power consumption data in this Wiki was last collected on May 15, 2013

The AM335x Power Consumption Summary discusses the power consumption for common system application usage scenarios for the AM335x ARM® Cortex™-A8 Microprocessors (MPUs). The metrics contained in this document serve to give users a better understanding of AM335x active power behaviors -- making it easier to determine a suitable configuration to meet a given power budget. Power consumption is highly dependent on the individual user’s application; however, this document focuses on providing several AM335x application-usage case scenarios and the environment settings that were used to perform such power measurements. This collection of real power measurements was measured on an AM335x GP EVM with a high-precision digital multimeter.

For additional details about the AM335x processor, please visit the TI.com product page.

Power Measurement Setup

The power measurements have been performed on the following platform:

  • Texas Instruments AM335x 15x15 GP EVM
    • Base Board Revision : 1.2A ("DDR2")
    • Base Board Revision : 1.5A ("DDR3")
    • General Purpose Daughterboard Revision : 1.2B
    • LCD Board Revision : 1.3A

* Note: These voltage rails are not available in the 13x13 package.

The "DDR3" measurements have an additional "VDDSDDRMEM" supply, which is brought up on the Rev1.5A GP EVM. This is not an AM335x voltage rail. It is used to measure the power consumption of the dual-loaded DDR3 + VTT.

High-level Summary

The following tables contain a high-level summary of the total device power (measured in milliwatts) for each application use case and/or configuration. For a detailed breakdown of the total device power over all 20 supplies, click on the corresponding link in the table cells.
