This section lists the typical current requirements of the baseboard.
Table B.2 lists the typical current requirements at room temperature and nominal voltage powered from the DC IN connector. These measurements include the current drawn by the JTAG interface, approximately 160mA at 3.3V. The actual operating current might be different for different versions of Core Tile or for Logic Tile FPGA images.
The maximum load on the external 12V supply is 43W.
Table B.2. Current requirements (from 12V DC IN)
System | Total power | DC IN (average) |
---|---|---|
baseboard and one Core Tile | 22W | 1.8A |
baseboard, one Core Tile, and two LT-XC2V6000 tiles | 31W | 2.6A |
baseboard, one Core Tile, and two LT-XC2V8000 tiles | 32W | 2.7A |
baseboard, one Core Tile, and four LT-XC2V8000 tiles | 43W | 3.6A |
baseboard, one Core Tile, and 3.8” CLCD | 32W | 2.7A |
baseboard, one Core Tile, and 8.4” CLCD | 38W | 3.2A |
Table B.3 lists the current requirements on the individual baseboard supplies.
If the board is powered from terminal connector J27 or the PCI connector, the maximum loading on any supply is limited to 6A.
Table B.3. Typical current loading on baseboard supplies
System | 3.3V typical | 5V typical | 12V typical |
---|---|---|---|
baseboard | 1.0A | 1.0A | <0.1A |
Core Tile | 0.5A | 2.0A | - |
LT-XC2V8000 | 0.5A | 0.8A | - |
8.4” CLCD | 0.1A | 0.1A | 0.5A |
