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
× V
CCQH and the maximum VILX should be no higher than 0.1 × VCCQH.
