Notes: 1. Refers to MODA/IRQA, MODB/IRQB, MODC/IRQC, and MODD/IRQD pins.
2. 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. Typical internal supply current is measured with VCCQP = 3.3 V,
VCC = 1.8 V at TJ = 100°C.
3. To obtain these results, all inputs must be terminated (that is, not allowed to float). PLL and XTAL
signals are disabled during Stop state.
4. DC current in Stop mode is evaluated based on measurements. To obtain these results, all inputs not
disconnected at Stop mode must be terminated (that is, not allowed to float).
5. Periodically sampled and not 100 percent tested.
6. VCCQH = 3.3 V ± 0.3 V, VCC = 1.8 V ± 0.1 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 × VCCQH and the maximum VILX should be no higher than 0.1 × VCCQH.
