Data Sheet

The NI 6581 is a 100 MHz digital adapter module for NI FlexRIO field-programmable gate array (FPGA) modules. This adapter module features 54 single-ended digital I/O lines with software-selectable voltages of 1.8, 2.5, and 3.3 (5 V tolerant). You can also reference an external voltage (ranging from 1.8V to 5.5V independently for each of the two connectors). You can combine it with an NI FlexRIO FPGA module to create an NI FlexRIO digital instrument (NI PXI-6581R) for a wide variety of applications from high-speed communication with a device under test to custom protocol emulation.

You can also use this adapter module with an NI FlexRIO FPGA module for customized semiconductor testing, electronics testing and interfacing, and implementation and testing of custom digital protocols.

In addition, you can configure the digital I/O lines as custom counter/timers, pulse-width modulation (PWM) channels, or communication buses for user-defined protocols or applications requiring serial triggering. You can even customize the communications with the onboard DRAM for optimized streaming operations.
