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.

2 Refers to MODA/IRQA, MODB/IRQB, MODC/IRQC, and MODD/IRQD pins.

3 Driving EXTAL to the low V

IHX 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 VCC and the maximum VILX should be no higher

than 0.1 VCC.

4 Periodically sampled and not 100% tested.

5 This characteristic does not apply to PCAP.

Section 5.3, "Power Consumption Considerations" 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 = 3.3 V at TJ = 100°C. Maximum internal supply current is measured with VCC = 3.46 V at TJ = 100°C.

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

float).
