Series 1 Adapter for Series 2 FPGA Boards

To the shop

The Series 1 Adapter board allows to use Series 2 FPGA Boards on application circuits for USB-FPGA Modules 1.∗. It also can be used as mounting adapter if no application circuit is present.

Usage instruction

The Series 1 Adapter can replace USB-FPGA Modules 1.∗ alone or in combination with a Power Supply Module. Depending on the usage, some of the 0 Ω resistors R1, R2 or R3 (package 1206; a piece of wire can be used instead) may be installed (also see the schematics). In order to prevent damage a few rules have to be kept:

Series 1 Adapter only replaces the USB-FPGA Module 1.∗: In this case the application circuit drives the power supply pins which are used by Series 1 FPGA Boards. Thus, R1 must not be installed.
Series 1 Adapter replaces a USB-FPGA Module 1.∗ and a Power Supply module: If the application circuit uses the 3.3V voltage from the Power Supply Module R1 has to be installed.
I/O voltage VCCO_IO is different to 3.3V: R2 has to be installed and the corresponding resistor on the FPGA board which connects VCCO_AB with 3.3V has to be removed. See the description for the Series 2 FPGA Board for details.
I/O voltage VCCO_TOP is different to 3.3V (USB-FPGA Modules 1.2 only): R3 has to be installed and the corresponding resistor on the FPGA board which connects VCCO_CD with 3.3V has to be removed. See the description for the Series 2 FPGA Board for details.

Pin assignment and net list

The pin assignment and net list can also be downloaded in Gnumeric or Excel format (several sheets).

The table shows the pin assignment of the Series 1 connector, e.g. pin A20 if the Series 1 connector is connected to pin A19 of the Series 2 FPGA Board.
