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 V
V = 1.8 V at T
CC
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.
