The timing waveforms shown in the AC electrical characteristics section are tested with a V
minimum of 2.0 V for all pins. AC timing specifications, which are referenced to a device input signal, are measured in
production with respect to the 50% point of the respective input signal’s transition. For all pins, output levels are measured with
the production test machine V

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 with Fsys < 200 MHz is
