5.3.4. MultiVolt I/O Interface in Arria® V Devices
The MultiVolt I/O interface feature allows Arria® V devices in all packages to interface with systems of different supply voltages.
VCCIO (V) | Device Variant Support | VCCPD (V) 0 | Input Signal (V) | Output Signal (V) |
---|---|---|---|---|
1.2 | All | 2.5 | 1.2 | 1.2 |
1.25 | All | 2.5 | 1.25 | 1.25 |
1.35 | All | 2.5 | 1.35 | 1.35 |
1.5 | All | 2.5 | 1.5, 1.8 | 1.5 |
1.8 | All | 2.5 | 1.5, 1.8 | 1.8 |
2.5 | All | 2.5 | 2.5, 3.0, 3.3 | 2.5 |
3.0 | GX, GT, SX, and ST | 3.0 | 2.5, 3.0, 3.3 | 3.0 |
GZ | 3.0 | 2.5, 3.0, 3.3 | 3.0, 3.3 | |
3.3 | GX, GT, SX, and ST | 3.3 | 2.5, 3.0, 3.3 | 3.3 |
The pin current may be slightly higher than the default value. Verify that the VOL maximum and VOH minimum voltages of the driving device do not violate the applicable VIL maximum and VIH minimum voltage specifications of the Arria® V device.
The VCCPD power pins must be connected to a 2.5 V, 3.0 V, or 3.3 V power supply. Using these power pins to supply the pre-driver power to the output buffers increases the performance of the output pins.
