10 Device and Documentation Support

TI offers an extensive line of development tools. Tools and software to evaluate the performance of the device,

generate code, and develop solutions are listed below.

10.1 Getting Started and Next Steps

For more information on the MSP low-power microcontrollers and the tools and libraries that are available to help

with development, visit the Texas Instruments Arm Cortex-M33 MCUs page.

10.2 Device Nomenclature

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all MSP

MCU devices and support tools. . Each MSP MCU commercial family member has one of two prefixes: MSP

or X. These prefixes represent evolutionary stages of product development from engineering prototypes (X)

through fully qualified production devices (MSP).

X – Experimental device that is not necessarily representative of the final device's electrical specifications

MSP – Fully qualified production device

X devices are shipped against the following disclaimer:

"Developmental product is intended for internal evaluation purposes." MSP 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 (X) have a greater failure rate than the standard production devices. TI

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 temperature

range, package type, and distribution format. Figure 10-1 provides a legend for reading the complete device

name.
