1 Voltage ranges are defined to group as many supplies as possible. Some supplies may have a wider range than listed here.

2 These are the supported frequencies included in the Linux, Android, and all other operating systems using the SCU defined

DVFS (Dynamic Voltage and Frequency Scaling) set points. An additional Overdrive set point is included to provide a more

balanced power-versus-performance trade-off, where the A72 runs at 1.3 GHz and the A53 runs at 1.1 GHz. Likewise, an

additional Nominal set point is included where both the A72 and A53 run at 600 MHz.

3 During low power state, this voltage can be dropped to 0.8 V +/- 3% for retention.

4 HDMI-RX and SATA are not currently supported, the related power and signal connections are provided for future use when

it is expected HDMI-RX and SATA support will be enabled.
