B.1.2. Current requirements
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 |
Powered from J27 or PCI bus
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 |
