AC Electrical Characteristics
The timing waveforms shown in the AC electrical characteristics section are tested with a V
IL
maximum of 0.8 V and a V
IH
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. DSP56720/DSP56721 output levels are
measured with the production test machine V
OL
and V
OH
reference levels set at 0.4 V and 2.4 V, respectively.

Notes:
1.
The Current Consumption section provides a formula to compute the estimated current 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
CORE_VDD
= 1.0V, V

= 3.3V at T

Maximum internal supply current is measured with V

= 3.6V at T
J
= 125°C.
In order to obtain these results, all inputs, which are not disconnected at Stop mode, must be terminated (i.e., not allowed to float).
