3.3 V Digital I/O on RIO Mezzanine Card Connector
Number of DIO channels........................96
Max tested current per channel...............±3 mA
Max total current, all lines ......................288 mA
Note
The performance of the RMC DIO lines is bounded by the FPGA, signal integrity,
the application timing requirements, and the RMC design. A general SPI application will
typically be able to meet these requirements and achieve frequencies of up to 10 MHz. For
