AC ELECTRICAL CHARACTERISTICS
The timing waveforms shown in the AC electrical characteristics section are tested with a V
IL
maximum of
0.3 V and a V
IH
minimum of 2.4 V for all pins except EXTAL, which is tested using the input levels shown
in
Note 8
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. DSP56364
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.
Note:
Although the minimum value for the frequency of EXTAL is 0 MHz, the
device AC test conditions are 15 MHz and rated speed.

Section 4.3,
Power Consumption Considerations
on page 3
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
CC
= 3.3 V at T
J
= 105°C. Maximum internal supply current is measured with V
CC
= 3.46 V at T
J
=
105°C.
In order to obtain these results, all inputs must be terminated (i.e., not allowed to float). PLL signal is
disabled during Stop state.
In order to obtain these results, all inputs, which are not disconnected at Stop mode, must be
terminated (i.e., not allowed to float).

This characteristic does not apply to PCAP.
Driving EXTAL to the low V

or the high V

value may cause additional power consumption (DC
current). To minimize power consumption, the minimum V

should be no lower than
