AM335x Device Information

In this page, you will find information to evaluate the device capabilities. If there are ever any discrepancies in information, the device data-sheet is considered the official source

Overview

This set of devices provide pin-pin and software compatible solutions allowing our customers to scale across multiple devices while saving their investment

All devices are available in the 15x15 mm, ZCZ package option. The 13x13 mm, ZCE package option is available for all devices, excluding AM3359 and AM3357.

See Device Nomenclature in datasheet and Parametrics table in product folders for speed ranges supported for each specific part number.

General Device Selection Guidelines:

• For a general overview of TI's ARM portfolio, see the ARM Platform Technical Guide Brochure.
• Also take a look at the Sitara Overview for help choosing a processor.
• For a comparison between ARM9, ARM11 and Cortex-A8, take a look at this matrix.

Package Reflow Profiles

• Package Reflow Profiles: Reflow profiles are dependent on numerous factors including package type, number of components, board layers, board size, reflow oven accuracy, process and more. Because of the number of variables it is not possible to provide a single reflow profile that is representative of every board using a specific package type. Typically, manufacturing houses have reflow profiles in place and modify them for specific hardware.
  The reflow profiles in this wiki article are provided as a reference to assist customers and manufacturing houses in customizing the reflow profile to specific hardware for the package type indicated. Therefore, the information provided is not considered a final reflow profile.

Pinmux Utility

• AM335x Pinmux Utility: The PinMux Utility v2.2.0.0 is a Windows-based software tool that provides a Graphical User Interface (GUI) for configuring pin multiplexing settings, resolving conflicts and specifying I/O cell characteristics for TI ARM Microprocessors. Results are output as C header files. The PinMux utility software discussed in this article can be downloaded at: http://focus.ti.com/docs/toolsw/folders/print/pinmuxtool.html.

Power

• AM335x Power Consumption Summary: The AM335x Power Numbers discusses the power consumption for common system application usage scenarios for the AM335x ARM® Cortex™-A8 Microprocessors (MPUs). 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.
• AM335x Power Estimation Tool: The Power Estimation Tool (PET) provides users the ability to gain insight in to the power consumption of select Sitara processors. The tool includes the ability for the user to choose multiple application scenarios and understand the power consumption as well as how advanced power saving techniques can be applied to further reduce overall power consumption.
