Notes:
1.
Refers to MODA/IRQA, MODB/IRQB, MODC/IRQC, and MODD/IRQD pins.
2.
Power Consumption Considerations on page 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. Typical internal supply current is measured
with VCC = 3.0 V at TJ = 100°C.
3.
To obtain these results, all inputs must be terminated (that is, not allowed to float).
4.
To obtain these results, all inputs that are not disconnected at Stop mode must be terminated (that is, not allowed to float). PLL
and XTAL signals are disabled during Stop state.
5.
Periodically sampled and not 100 percent tested.
6.
VCC = 3.3 V ± 0.3 V; TJ = –40°C to +100 °C, CL = 50 pF
7.
This characteristic does not apply to XTAL and PCAP.
8.
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
× VCC and the maximum VILX should be no higher than 0.1 × VCC.
