2.4 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 Notes 7
and 9 of the previous table. AC timing specifications, which are referenced to a device input signal, are measured in
production with respect to the 50 percent point of the respective input signal’s transition. DSP56321 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 16
MHz and rated speed with the DPLL enabled.

Notes:
1.
Power-up sequence: During power-up, and throughout the DSP56321 operation, VCCQH voltage must always be higher or
equal to VCCQL voltage.
2.
Refers to MODA/IRQA, MODB/IRQB, MODC/IRQC, and MODD/IRQD pins.
3.
Section 4.3 provides a formula to compute the estimated current requirements in Normal mode. To obtain these results, all
inputs must be terminated (that is, not allowed to float). Measurements are based on synthetic intensive DSP benchmarks (see
Appendix A). The power consumption numbers in this specification are 90 percent of the measured results of this benchmark.
This reflects typical DSP applications.
4.
To obtain these results, all inputs must be terminated (that is, not allowed to float).
5.
To obtain these results, all inputs not disconnected at Stop mode must be terminated (that is, not allowed to float), and the
DPLL and on-chip crystal oscillator must be disabled.
6.
Periodically sampled and not 100 percent tested.
7.
VCCQH = 3.3 V ± 0.3 V, VCQLC = 1.6 V ± 0.1 V; TJ = –40°C to +100 °C, CL = 50 pF
8.
This characteristic does not apply to XTAL.
9.
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
× VCCQH and the maximum VILX should be no higher than 0.1 × VCCQH.
