• Data rate: variable
For more ash memory details, see the Micron MT25QU01GBBB8E12-0SIT data sheet at the
Micron website.
For conguraon details, see the UltraScale Architecture Conguraon User Guide (UG570). The
detailed FPGA and Flash pin connecons for the feature described in this secon are
documented in the Alveo U200/U250 accelerator card XDC le, referenced in Appendix A: Xilinx
Design Constraints (XDC) File.
USB JTAG Interface
The Alveo accelerator card provides access to the FPGA device via the JTAG interface.
FPGA conguraon is available through the Vivado
®
hardware manager, which accesses the on-
board USB-to-JTAG FT4232HQ bridge device. The micro-AB USB connector on the Alveo U200/
U250 accelerator card PCIe
®
panel/bracket provides external device programming access.
Note: JTAG conguraon is allowed at any me regardless of the FPGA mode pin sengs consistent with
the UltraScale Architecture Conguraon User Guide (UG570).
For more details about the FT4232HQ device, see the FTDI website: hps://www.dichip.com/.
FT4232HQ USB-UART Interface
The FT4232HQ Quad USB-UART provides a UART connecon through the micro-AB USB
connector. The FPGA UART TX/RX (two-wire) connecon is made through the FT4232HQ BD
port. Channel BD implements a 2-wire level-shied TX/RX UART connecon to the FPGA. The
FTDI FT4232HQ data sheet is available on the FTDI website: hps://www.dichip.com/.
PCI Express Endpoint
The Alveo U200/U250 accelerator card implements a 16-lane PCI Express
®
edge connector that
performs data transfers at the rate of 2.5 giga-transfers per second (GT/s) for Gen1, 5.0 GT/s for
Gen2, and 8.0 GT/s for Gen3 applicaons. The -2 speed grade FPGA included with the cards
supports up to Gen3 x16.
