3.3.8 Power Tree
The CYC5000 is powered by MPM Power Modules which provide high efficiency on a small layout.
As seen from the diagram below, the board can be powered either by a micro-USB connection or
by user input voltage from the Arduino MKR header (takes precedence over the USB bus). All
devices are powered by a 3.3V voltage line and the 5V and 3.3V lines are fed back to the Arduino
header to power that connection if needed. The Cyclone V FPGA is powered by 3 power modules,
while a Microchip LDO provides auxiliary voltage.
Because of the ‘Power Good’ and ‘Power Enable’ signals of modules, there is no need for a
separate power supply controller to manage the power sequencing.
