D2-7xx83
Electrical Specifications TA = +25°C, CVDD = PLLVDD = 1.8V ±5%, RVDD = PWMVDD = 3.3V ±10%. All grounds at 0.0V. All voltages
referenced to ground. PLL at 294.912MHz, OSC at 24.576MHz, core running at 147.456MHz with typical audio data traffic. Minimum supply currents are
measured in full power down configuration. (Continued)

NOTES:
8. All input pins except XTALI.
9. Input leakage applies to all pins except XTALO.
10. Power-down is with device in reset and clocks stopped.
11. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
12. Limits established by characterization and are not production tested.
