Pipistrello Rev 2.0 Hardware Description



Board features:

FPGA: Spartan-6 LX45 in 324 BGA package, speed grade -3C

Flash memory: 128 Mbit SPI flash memory (Micron N25Q128A13ESE40G) wired for 1x, 2x or 4x wide data path

On-board DRAM: 64 MBytes (32Mx16) of LPDDR memory (Micron MT46H32M16LFBF-5) clocked at 200 MHz (up to 800 MBytes/s transfer rate), supported by Xilinx MIG

USB device interface: High-speed (480 Mbits/s) interface using a 2-channel FTDI FT2232H chip. Channel A is wired for JTAG. Channel B is wired for serial (max 12 Mbaud) or async FIFO mode (max 8 MB/s).

DVI/HDMI interface: Full HDMI output interface (including I2C level translators for DDC) using a 19-pin HDMI type A connector

Audio output: Two-channel audio output using 1-bit sigma-delta DAC

Micro-SD card: Socket for micro-SD card, wired for SPI or native (4x wide) SD interface

PMOD interface: Double-row PMOD connector that will allow the use of a wide range of PMOD devices (see below for more info on PMOD devices)

LED indicators: Power (green), config state (yellow), five user-defined

User I/O: Papilio-style wing interface with 48 user-defined I/O signals. The boards have female headers installed on the wing interface.

Form factor: Similar to Papilio One (2.9" x 2.7")



LPDDR memory supported by Xilinx MIG (Memory Interface Generator) and Xilinx EDK/XPS (Embedded Platform System).



Assembled and tested in USA

Xilinx ISE support files

Generic ucf file, edit as needed Updated 5/20/2016

EDK board description files Unzip and copy Saanlima directory to C:\Xilinx\XX.X\ISE_DS\EDK\board (windows) or /opt/Xilinx/XX.X/ISE_DS/EDK/board (linux)

Latest (final) version of ISE (14.7) can be downloaded from here: Xilinx ISE 14.7

The board is fully supported by 3rd party JTAG programming tools like fpgaprog or xc3sprog without the need for a Xilinx JTAG cable.





Fpgaprog utility program download

JTAG programming utility (including source code and binary):

On Linux you might have to give yourself root access to the ftdi device. See this forum post for more info.

The board can also be used with xc3sprog (see this link).





GUI frontend to fpgaprog

This is a modified version of Scarab's miniSProg. More info here.

For more info on miniSProg see this github page





Bit files (see below for complete Xilinx projects)

To download one of the bit files just right-click on a link and select "save link as"

The bit files can be loaded to ram (fpgaprog -v -f <bitfile>) or written to flash (fpgaprog -v -f <bitfile> -b bscan_spi_lx45_csg324.bit -sa -r)
