The BRK7010 is a simple two-layer “breakout board” which can be used to evaluate or transition to the XEM7010. It provides standard 2-mm thru-hole connections to the 0.8-mm high-density connectors on the XEM7010 and a DC power connector (2.1mm / 5.5mm, center positive) for providing +5VDC to the XEM7010.
Xilinx JTAG Operation
The BRK7010 passes the JTAG interface from the expansion connectors on the XEM7010 to a connector compatible with the Xilinx JTAG cable. The reference voltage of this interface needs to be compatible with the XEM7010. Selection of this is done using a shunt on JP1 according to the table below.
|FPGA PRODUCT||JTAG REFERENCE VOLTAGE||SHUNT POSITION|
|XEM7010||3.3 V||Pins 2 – 3|
|XEM7310||1.8 V||Pins 1 – 2|
