Digital Ground.
(1)
Notes:
1. All odd pins (1, 3, 5, 7, 9, 11, and 13) should be connected to digital ground on the target end of the ribbon cable. Minimum crosstalk is
achieved when using all grounds.
2. The listed SPI pin names match those of SPI flash memories from STMicroelectronics. Pin names of compatible SPI devices from other
vendors can be different. Consult the vendor's SPI device data sheet for corresponding pin names.
Caution! The PROG_B pin of the FPGA, which is connected to a target SPI device, must be asserted Low during SPI programming to
ensure the FPGA does not contend with the SPI programming operation.
3. The target reference voltage must be regulated and must not have a current-limiting resistor in series with the V
REF
pin.

Notes:
1. Operating at Hi-Speed on a USB 2.0 port. The I
CC1
value in the table applies to the DLC9G and legacy DLC9LP cable models. The legacy
DLC9 cable model I
CC1
value is 230 mA.
2. Operating at full-speed on a low-power USB 1.1 port. The I
CC2
table value applies to the DLC9G and legacy DLC9LP cable models. The
legacy DLC9 cable model I
CC2
value is 98 mA.
3. Exposure to Absolute Maximum Rating conditions for extended periods of time can affect product reliability. These are stress ratings only and
functional operation of the product at these or any other condition beyond those listed under Recommended Operating Conditions is not implied.
