symbolization and speed ratings

The device revision can be determined by the lot trace code marked on the top of the package. The location

for the lot trace codes for the PGE package is shown in Figure 13.

TMS320VC33 devices are rated in peak MFLOPS, shown as a suffix to the orderable part number (see Table 8).

Figure 13 shows the device symbolization on the PGE package. A general “TMS320VC33” symbol defaults to

the lowest speed rating for that device (120 MFLOPS). 150-MFLOPS devices are denoted with a “150” mark

on the upper right-hand corner of the package. The VC33 CPU instruction rate is MFLOPS/2.
