5.x Xchecker - How can I use it on low-power "L" 3.3V parts?


Several Xilinx families now have members that are low-power 3.3V parts,
such as the 3000L and the 4000L. The Xchecker cable itself is designed
for use with 5V parts, but there is a special adapter that will allow
operation with 3.3V parts.


As detailed in the "HardWare & Peripherals User Guide", pg.3-3, an optional
3.3V adapter to the Xchecker accepts Vcc supplies from 2.9V to 5.25V. This
adapter contains a voltage step-up circuit that generates the 5V needed by

Since it can accept voltages up to 5.25V, there is no need to remove the
adapter when using 5V parts.

The adapter's order # is: HW-XCH3V
