Before performing a test to verify the power-up time of a MAX II device
under a certain load, you should set the V
depending on what it will be in the final system. The shunt on J9 controls
this value. If the shunt is present on J9, the MAX II device’s V
2.5 V; if the shunt is not present on J9, the V
The MAX II device data sheet specifies that a MAX II device will be
functional less than 300 μs after minimum V
actuality, configuration starts at a voltage below minimum V
device on a board where the V
powered-up and configured before the supply reaches minimum V
The Power-up demo allows users to investigate the power-up time in two
different ways. The first is a race against the MAX II device that helps
define what “Instant-on” means. The second is a much more detailed
investigation of the power-up time that requires an oscilloscope, but
provides a thorough understanding of how a MAX II device powers up
under different loads.
On Board Circuit
The circuit on the board consists of a power regulator that provides the
V
or removing a shunt on J9. (If the shunt is in place, V
shunt is not in place, V
increased by a variable resistor (POT1). Four test points are also provided
on the board: V
test points are labeled Active I/O Test Points and are located near the
prototyping area on the board. Refer to the MAX II Development Board
Data Sheet if you cannot locate the test points on your board. These test
points allow for oscilloscope probes to be attached so the outputs can be
thoroughly examined.

This test is meant to verify the data provided in the MAX II
Device Data Sheet, not to replace it. All MAX II devices will have
some fluctuation in power-up timing. Designers should ensure
that systems relying on a MAX II device to perform power up
functions are using the MAX II device in accordance with the
specifications given in the Data Sheet.
