Figure 6-3. Typical Operational Power Versus Frequency
NOTE
Typical operational current for 100-MHz devices (28x32) can be estimated from Figure 6-2.
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.
6.5
Emulator Connection Without Signal Buffering for the DSP
Figure 6-4 shows the connection between the DSP and JTAG header for a single-processor configuration.
If the distance between the JTAG header and the DSP is greater than 6 inches, the emulation signals
must be buffered. If the distance is less than 6 inches, buffering is typically not needed. Figure 6-4 shows
the simpler, no-buffering situation. For the pullup/pulldown resistor values, see the pin description section.
