Figure 6-2. Typical Operational Power Versus Frequency (F28335/F28235/F28334/F28234)  
NOTE  
Typical operational current for 100-MHz devices (28x32) can be estimated from Figure 6-1.  
Compared to 150-MHz devices, the analog and flash module currents remain unchanged.  
While a marginal decrease in IDDIO current can be expected due to the reduced external  
activity of peripheral pins, current reduction is primarily in IDD  
.
6.4.3 Thermal Design Considerations  
Based on the end application design and operational profile, the IDD and IDDIO currents could vary.  
Systems with more than 1 Watt power dissipation may require a product level thermal design. Care should  
be taken to keep Tj within specified limits. In the end applications, Tcase should be measured to estimate  
the operating junction temperature Tj. Tcase is normally measured at the center of the package top side  
surface. The thermal application notes IC Package Thermal Metrics (literature number SPRA953) and  
Reliability Data for TMS320LF24xx and TMS320F28xx Devices (literature number SPRA963) help to  
understand the thermal metrics and definitions.
