Document Table of Contents Passive Serial Multi-Device Configuration Using a Download Cable

You can also use a download cable to configure multiple Intel® Cyclone® 10 LP device configuration pins.

The download cable could be an Intel FPGA download cable or Intel FPGA Ethernet cable.

Note: Power up the VCC of the Intel FPGA download cable with a 2.5-V supply from VCCA. Third-party programmers must switch to 2.5 V.

Note: The pull-up resistors on DATA[0] and DCLK are only required if the download cable is the only configuration scheme used on your board. This is to ensure that DATA[0] and DCLK are not left floating after configuration. For example, if you also use a configuration device, the pull-up resistors on DATA[0] and DCLK are not required.

When a device completes configuration, its nCEO pin is released low to activate the nCE pin of the next device. Configuration automatically begins for the second device.
