SCBS881E January 2010 – October 2018 TMS3705
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of devices. Each device has one of three prefixes: X, P, or null (no prefix) (for example, TMS3705).
Device development evolutionary flow:
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 (X or P) 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 package type (for example, D). Figure 8-1 provides a legend for reading the complete device name.
