10 Device and Documentation Support

10.1 Device Support

10.1.1 Development Support

TI offers an extensive line of development tools, including tools to evaluate the performance of the processors, generate code, develop algorithm implementations, and fully integrate and debug software and hardware modules. The tool's support documentation is electronically available within the Code Composer Studio™ Integrated Development Environment (IDE).

The following products support development of AM389x processor applications:

Software Development Tools: Code Composer Studio™ Integrated Development Environment (IDE): including Editor C/C++ and Assembly Code Generation, and Debug plus additional development tools Scalable, Real-Time Foundation Software , which provides the basic run-time target software needed to support any Sitara ARM Processor application.

Hardware Development Tools: Extended Development System (XDS™) Emulator

For a complete listing of development-support tools for the AM389x Sitara™ ARM Processor platform, visit the Texas Instruments website at www.ti.com. For information on pricing and availability, contact the nearest TI field sales office or authorized distributor.

10.1.2 Device and Development Support-Tool Nomenclature

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all processors and support tools. Each device has one of three prefixes: X, P, or null (no prefix) (for example, AM3894CYG120). Texas Instruments recommends two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMDX) through fully qualified production devices and tools (TMDS).

Device development evolutionary flow:

    XExperimental device that is not necessarily representative of the final device's electrical specifications and may not use production assembly flow.
    PPrototype device that is not necessarily the final silicon die and may not necessarily meet final electrical specifications.
    nullProduction version of the silicon die that is fully qualified.

Support tool development evolutionary flow:

    TMDXDevelopment-support product that has not yet completed Texas Instruments internal qualification testing.
    TMDSFully-qualified development-support product.

X and P devices and TMDX development-support tools are shipped against the following disclaimer:

"Developmental product is intended for internal evaluation purposes."

Production devices and TMDS development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI's standard warranty applies.

Predictions show that prototype devices (X or P) have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used.

TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, CYG), the temperature range (for example, blank is the default commercial operating junction temperature range), and the device speed range (for example, 120 is 930-MHz ARM). Figure 10-1 provides a legend for reading the complete device name for any AM389x device.

For device part numbers and further ordering information of AM389x devices in the CYG package type, see the TI website (www.ti.com) or contact your TI sales representative.

For additional description of the device nomenclature markings on the die, see the AM389x Sitara ARM Processors Silicon Errata (literature number SPRZ327).

10.6 Electrostatic Discharge Caution

esds-image

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
