Pipistrello Rev 2.0 Hardware Description
FPGA: Spartan-6 LX9, LX16, LX25 or LX45 in 324 BGA package
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) in 60 BGA package
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 or async FIFO mode.
DVI/HDMI interface: Full HDMI 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")
Assembled and tested in USA
