5. Using MAX V Devices in Multi-Voltage  
Systems  
December 2010  
MV51005-1.0  
MV51005-1.0  
This chapter describes how to implement Altera® devices in multi-voltage systems  
without damaging the device or the system.  
Technological advancements in deep submicron processes have lowered the supply  
voltage levels of semiconductor devices, creating a design environment where devices  
on a system board may potentially use many different supply voltages such as 5.0, 3.3,  
2.5, 1.8, 1.5, and 1.2 V, which can ultimately lead to voltage conflicts.  
To accommodate interfacing with a variety of devices on system boards, MAX® V  
devices have MultiVolt I/O interfaces that allow devices in a mixed-voltage design  
environment to communicate directly with MAX V devices. The MultiVolt interface  
separates the power supply voltage (VCCINT) from the output voltage (VCCIO),  
allowing MAX V devices to interface with other devices using a different voltage level  
on the same PCB. The 1.8-V input directly powers the core of the MAX V devices.  
f For more information about hot socketing and power-on reset (POR), refer to the Hot  
Socketing and Power-On Reset in MAX V Devices chapter.  
This chapter contains the following sections:  
“I/O Standards” on page 5–1  
“MultiVolt I/O Operation” on page 5–3  
“5.0-V Device Compatibility” on page 5–3  
“Recommended Operating Conditions for 5.0-V Compatibility” on page 5–7  
“Power-Up Sequencing” on page 5–8  
I/O Standards  
The I/O buffer of MAX V devices is programmable and supports a wide range of I/O  
voltage standards. You can program each I/O bank in a MAX V device to comply  
with a different I/O standard. You can configure all I/O banks with the following  
standards:  
3.3-V LVTTL/LVCMOS  
2.5-V LVTTL/LVCMOS  
1.8-V LVTTL/LVCMOS  
1.5-V LVCMOS  
1.2-V LVCMOS  
Emulated LVDS output (LVDS_E_3R)  
Emulated RSDS output (RSDS_E_3R)
