device and development support tool nomenclature (continued)
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type
(for example, PG, PGE, and PZ) and temperature range (for example, A). Figure 15 provides a legend for
reading the complete device name for any TMS320x2xx family member. Refer to the timing section for specific
options that are available on 240x devices.
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.
