This chapter describes how to implement Altera
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
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 (V
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.

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:
