SPRS282E–DECEMBER 2005–REVISED MARCH 2007
Predictions show that prototype devices (TMX or TMP) 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, ZWT), the temperature range (for example, "Blank" is the commercial
temperature range), and the device speed range in megahertz (for example, "Blank" is the default
[594-MHz DSP, 297-MHz ARM9]).
