9 Device and Documentation Support

9.1 Getting Started and Next Steps

To get started using a RM Hercules™ ARM® Cortex®-R Microcontroller (MCU):

  1. Purchase a RM LaunchPad Development Kit with the LaunchPAD Quickstart Guide included.

    2. From the LaunchPAD Quickstart Guide, the user can easily determine the correct Code Composer Studio™ (CCS) Integrated Development Environment (IDE) and Hardware Abstraction Layer Code Generator (HALCoGen™) GUI-based chip configuration tool for any selected Hercules MCU device(s).

  2. Download the latest version of CCS IDE for Safety MCUs for the specified host platform (that is, Windows, Linux, or MacOS) (free as long as using a LaunchPAD or a Hercules MCU Development Kit [HDK])
  3. Under Order Now, download the HALCOGEN: HAL Code Generator tool.
  4. For additional tools and software descriptions, web page links, key docs, and so forth, see Tools and Software.

The Hercules RM family also has TI BoosterPack™ plug-in modules available that fit on top of a LaunchPad development kit.

9.2 Device and Development-Support Tool Nomenclature

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all devices.Each device has one of three prefixes: X, P, or null (no prefix) (for example, xRM44L920). These prefixes represent evolutionary stages of product development from engineering prototypes through fully qualified production devices.

Device development evolutionary flow:

    x Experimental device that is not necessarily representative of the final device's electrical specifications and may not use production assembly flow.
    P Prototype device that is not necessarily the final silicon die and may not necessarily meet final electrical specifications.
    null Fully-qualified production device.

x and P devices are shipped against the following disclaimer:

"Developmental product is intended for internal evaluation purposes."

Production devices 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 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.

Figure 9-1 shows the numbering and symbol nomenclature for the RM44Lx20 devices.

The following links connect to TI community resources. Linked contents are provided "AS IS" by the respective contributors. They do not constitute TI specifications and do not necessarily reflect TI's views; see TI's Terms of Use.

    TI E2E™ Online Community The TI engineer-ro-engineer (E2E) community was created to foster collaboration among engineers. At e2e.ti.com, you can ask questions, share knowledge, explore ideas and help solve problems with fellow engineers.
    TI Embedded Processors Wiki Established to help developers get started with Embedded Processors from Texas Instruments and to foster innovation and growth of general knowledge about the hardware and software surrounding these devices.
    Hercules™ Safety Microcontrollers Forum TI's Hercules™ Safety Microcontrollers Forum was created under the E2E umbrella to foster collaboration among engineers, ask questions, share knowledge, explore ideas, and help solve problems, specifically relating to the Hercules Safety MCUs (that is, TMS570 and RM families).
    SafeTI™ Documentation Private E2E Forum A private E2E forum to request access to the safety analysis report; ask questions; share knowledge; and explore ideas to help resolve problems relating to the safety analysis report. This forum is closely monitored by the TI Safety experts. The safety analysis report itself includes detailed device-level Failure Modes, Effects, and Diagnostics Analysis (FMEDA) for ISO 26262 functional safety applications. The report also includes tools for estimating module and device-level failure rates (fault insertion tests (FIT) rates).

9.8 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.
