The timing waveforms shown in the AC electrical characteristics section are tested with a V
of 0.3 V and a V
shown in Note 6 of the previous table. 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.
DSP56362 output levels are measured with the production test machine V
at 0.4 V and 2.4 V, respectively.

This characteristic does not apply to PCAP.

requirements in Normal mode. In order to obtain these results, all inputs must be terminated (i.e., 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
In order to obtain these results, all inputs, which are not disconnected at Stop mode, must be terminated (i.e., not allowed to
float).
