Enclustra Mercury+ XU6 - Power

2.11 Power
2.11.1 Power Generation Overview
The Mercury+ XU6 SoC module uses a 5 - 15 V DC power input for generating the on-board supply voltages
(0.72/0.85/0.9 V, 0.85/0.9 V, 0.9 V, 1.2 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). Some of these voltages (1.8 V, 2.5 V, 3.3
V) are accessible on the module connector.
Table 13 describes the power supplies generated on the module.

Table 13: Generated Power Supplies
In the standard configuration, the PL core supply is 0.85 V. For custom product configurations, in which a
speedgrade -3E MPSoC device is equipped, an assembly option is available to switch the PL core operating
voltage to 0.9 V. Similarly, in situations in which a speedgrade -2LE or -1LI device is used, an assembly option
is available to switch the PL core operating voltage to 0.72 V.
In the standard configuration, the PS core supply is 0.85 V. For custom configurations, in which a speedgrade
-3E MPSoC device is equipped, an assembly option is available to switch the PS core operating voltage to
0.9 V.
Please refer to the Enclustra Module Pin Connection Guidelines for general rules on the power pins [10].
2.11.2 Power Enable/Power Good
The Mercury+ XU6 SoC module provides a power enable input on the module connector. This input may
be used to shut down the DC/DC converters and LDOs for 0.6 V, 0.72/0.85/0.9 V, 0.85/0.9 V, 0.9 V, 1.2 V, 1.8
V and 2.5 V. The list of regulators that can be disabled via PWR_EN signal is provided in Section 2.11.1.
