AC Electrical Characteristics

AC ELECTRICAL CHARACTERISTICS

The timing waveforms shown in the AC electrical characteristics section are tested with a VIL maximum of

0.3 V and a VIH minimum of 2.4 V for all pins except EXTAL, which is tested using the input levels 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 VOL and VOH 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.

Power Consumption Considerations on page 4-3 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 VCC = 3.3V at TJ = 100°C. Maximum internal supply current is measured with VCC =

3.46 V at TJ = 100°C.

Deleted.

In order to obtain these results, all inputs, which are not disconnected at Stop mode, must be

terminated (i.e., not allowed to float).

Periodically sampled and not 100% tested

VCC = 3.3 V ± 5% V; TJ = 0°C to +100°C, CL = 50 pF

This characteristic does not apply to PCAP.

Driving EXTAL to the low VIHX or the high VILX value may cause additional power consumption (DC

current). To minimize power consumption, the minimum VIHX should be no lower than

0.9

ξ VCC and the maximum VILX should be no higher than 0.1 ξ VCC.
