Each MAX V device I/O pin provides an optional programmable pull-up resistor
during user mode. If you enable this feature for an I/O pin, the pull-up resistor holds
the output to the V
The programmable pull-up resistor feature should not be used at the same time as the
bus-hold feature on a given I/O pin.
The programmable pull-up resistor is active during power-up, ISP, and if the device is
unprogrammed.
The MAX V IOE includes a programmable input delay that is activated to ensure zero
hold times. A path where a pin directly drives a register, with minimal routing
between the two, may require the delay to ensure zero hold time. However, a path
where a pin drives a register through long routing or through combinational logic
may not require the delay to achieve a zero hold time. The Quartus II software uses
this delay to ensure zero hold times when needed.
The MAX V architecture supports the MultiVolt I/O interface feature, which allows
MAX V devices in all packages to interface with systems of different supply voltages.
The devices have one set of VCC pins for internal operation (V
sets for input buffers and I/O output driver buffers (V
number of I/O banks available in the devices where each set of VCCIO pins powers one
I/O bank. The 5M40Z, 5M80Z, 5M160Z, 5M240Z, and 5M570Z devices each have two
I/O banks while the 5M1270Z and 5M2210Z devices each have four I/O banks.
Connect VCCIO pins to either a 1.2-, 1.5-, 1.8-, 2.5-, or 3.3-V power supply, depending
on the output requirements. The output levels are compatible with systems of the
same voltage as the power supply (that is, when VCCIO pins are connected to a 1.5-V
power supply, the output levels are compatible with 1.5-V systems). When VCCIO pins
are connected to a 3.3-V power supply, the output high is 3.3 V and is compatible with
3.3-V or 5.0-V systems.
