1.10.1 Operating Voltage Rails
(Ask a Question)SmartFusion2/IGLOO2 devices need 1.2V for the core supply and either 2.5V or 3.3V for I/O and analog supplies. The following table lists operating voltage requirements for the devices.
Pin Name | Description | Operating Voltage |
---|---|---|
VDD | DC core supply voltage | 1.2V |
VDDIx1 | I/O bank supply | 1.2V, 1.5V, 1.8V, 2.5V, or 3.3V |
SERDES_x_VDD | PCIe/PCS supply | 1.2V |
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 | 1.2V |
VPP2 | Power supply for charge pump | 2.5V or 3.3V |
VPPNVM1 | Analog sense-circuit supply for the embedded nonvolatile memory (eNVM). | 2.5V or 3.3V |
CCC_xyz_PLL_VDDA | Analog power pad for CCC PLL |
2.5V or 3.3V |
MSS/HPMS_xDDR_PLL_VDDA | Analog power pad for xDDR PLL | 2.5V or 3.3V |
SERDES_x_PLL_VDDA | High supply voltage for SerDes PLL | 2.5V or 3.3V |
SERDES_x_L[01/23]_VDDAPLL | Analog power for SerDes PLL of lanes 0, 1, 2, and 3 | 2.5V |
Note:
- The 3.3 V supply can be connected to MSIO VDDIx bank only.
- For M2S090T(S), M2S150T(S) devices, VPP, and VPPNVM must be connected to 3.3 V.
