6 Power
The phyCORE
‑
i.MX 6UL/ULL operates off of a single power supply voltage.
The following sections discuss the primary power pins on the phyCORE
‑
Connector X1 in detail.
6.1 Primary System Power (VDD_3V3)
The phyCORE
‑
i.MX 6UL/ULL operates off of primary voltage supply with a nominal value of +3.3 V. On-board
switching regulators generate the DDR3L voltage 1.35 V and the core voltage 1.4 V which is switchable to 1.3 V or
0.925 V for power saving reasons.
For proper operation the phyCORE
‑
i.MX 6UL/ULL must be supplied with a voltage source of 3.3 V ±5 % connected to
the VCC pins of phyCORE-Connector X1.
VDD_3V3: X1 90, 91, 92, 93
Connect all +3.3 V VCC input pins to your power supply and at least the matching number of GND pins.
Corresponding GND: X1 1, 32, 62, 89
Please refer to
for information on additional GND Pins located at the phyCORE
‑
Connector X1.
