For MAX 10 single-supply devices, only one power supply is required—3.0 V or 3.3 V to power the core
of the FPGA. The same power supply can be used to power the I/O if the same 3.0 V or 3.3 V voltage is
required. If different I/O voltage is used, then additional voltage regulators will be needed.
For MAX 10 dual-supply devices, two power supplies are required to supply power to the device core,
periphery, phase-locked loop (PLL), and analog-to-digital converters (ADC) blocks—1.2 V and 2.5 V.
Depending on the I/O standard voltage requirement, you may use two or more voltage regulators.
As the power rails for the FPGA core are supplied externally in the MAX 10 dual-supply devices, the
design can be optimized for power by using high efficiency switching power supplies on the board. The
power savings will be equal to the increased efficiency of the regulators used compared to the internal
linear regulators of the MAX 10 single-supply devices. If linear regulators are used to power the MAX 10
dual-supply devices, the power consumption of the MAX 10 dual-supply devices will be approximately
equal to the MAX 10 single-supply devices.
The device performance of the single-supply device is lower than that of the dual-supply device. For the
performance difference in terms of LVDS, pseudo-LVDS, digital signal processing (DSP), and internal
memory performance, refer to the MAX 10 FPGA device datasheet.

This shows the number of power supplies required by the core and periphery of the MAX 10 devices. You
may need additional voltage regulators to supply power to the
VCCIO
if the
VCCIO
does not have the same
voltage level as the core and periphery supply.
