Operating Voltage Rails

SmartFusion2/IGLOO2 devices need 1.2 V for the core supply and either 2.5 V or 3.3 V for I/O and analog supplies. The following table lists operating voltage requirements for the devices.

Description

Operating Voltage

VDD

DC core supply voltage

1.2 V

VDDIx1

I/O bank supply

1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V

SERDES_x_VDD

PCIe/PCS supply

1.2 V

SERDES_x_L[01/23]_VDDAIO

Tx/Rx analog I/O voltage. Low-voltage power for lanes 0, 1, 2, and 3 of the SerDes interface

1.2 V

VPP2

Power supply for charge pump

2.5 V or 3.3 V

VPPNVM1

Analog sense-circuit supply for the embedded nonvolatile memory (eNVM).

2.5 V or 3.3 V

CCC_xyz_PLL_VDDA

Analog power pad for CCC PLL

2.5 V or 3.3 V

MSS/HPMS_xDDR_PLL_VDDA

Analog power pad for xDDR PLL

2.5 V or 3.3 V

SERDES_x_PLL_VDDA

Notes:
  1. 1.The 3.3 V supply can be connected to MSIO VDDIx bank only.
  2. 2.For M2S090T(S), M2S150T(S) devices, VPP, and VPPNVM must be connected to 3.3 V.
