AC Electrical Characteristics

The timing waveforms shown in the AC electrical characteristics section are tested with a V
of 0.8V and a V
device input signal, are measured in production with respect to the 50% point of the respective input
signal’s transition. DSP56371 output levels are measured with the production test machine V
reference levels set at 1.0V and 1.8V, respectively.

Note:
• In Wait mode
• In Stop mode
Although the minimum value for the frequency of EXTAL is 0 MHz (PLL bypassed), the
device AC test conditions are 5 MHz and rated speed.

Section 3, Power Consumption Considerations
Normal mode. In order to obtain these results, all inputs must be terminated (for example, not allowed to float).
Measurements are based on synthetic intensive DSP benchmarks. The power consumption numbers in this
specification are 90% of the measured results of this benchmark. This reflects typical DSP applications. Typical internal
supply current is measured with V
