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, PAG, PG, PGE, and PZ) and temperature range (for example, A). Figure 19 provides a legend
for reading the complete device name for any TMS320x240xA family member. Refer to the timing section for
specific options that are available on 240xA 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.

The package dimensions of the 2407A and 2406A devices correspond to the LQFP package. These devices were stated to be
in TQFP packaging in the TMX data sheets. The package dimensions have
not
changed; only the package designation has
changed.
