Notes: 1. Refers to MODA/IRQA, MODB/IRQB, MODC/IRQC, and MODD/IRQD pins.
2. Secton 4.3 Power Consumption Considerations on page 4-4 provides a formula to compute the
estimated current requirements in Normal mode. In order 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 = 3.3 V at TJ = 100°C.
3. In order to obtain these results, all inputs must be terminated (that is, not allowed to float).
4. In order 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.
