Introduction
Connect Tech’s FreeForm/Express S6 is a reconfigurable computing platform that is based on the
Xilinx Spartan-6 FPGA; featuring integrated PCI Express® blocks, advanced memory support,
and 3.125 Gbps low-power transceivers. The FreeForm/Express S6 includes an industry-standard
FPGA Mezzanine Card (FMC) connector, which provides a flexible I/O interface for future
scaling and customization. The PCIe bus bandwidth ensures high speed communication between
the host system and the application’s interfaces.
A wide range of available FMC modules adds interfaces such as ADC and digital video, which
makes the FreeForm/Express S6 a highly versatile platform for system development. It is ideally
suited for applications requiring both prototyping and field deployment including real-time data
acquisition, high performance video processing, and software defined radio. The
FreeForm/Express S6 is optimized for embedded processor designs, supporting development with
Xilinx’s MicroBlaze.

What is an FPGA Mezzanine Card (FMC)?
An FPGA Mezzanine Card (FMC) is a standard created by VITA (VMEbus International Trade
Association). The FMC standard (VITA 57.1) defines a module size and connector interface with
generic reconfigurable I/O, making it perfect for FPGA daughter board applications. The standard
defines two pin-outs, low pin count (LPC) and high pin count (HPC); with each type using the
same connector form factor.

Hardware Description
FPGA
Description
The FreeForm/Express S6 features the Xilinx Spartan-6 LX45T FPGA in a 484 pin BGA package
(Xilinx XC6SLX45T-2FGG484I). The Spartan-6 simplifies FPGA design by providing a
integrated memory controller and PCI express end point, along with high performance general I/O,
clocking, and internal memory resources comparable to be previous generation Virtex-class
FPGAs.
For more details on the Spartan-6 capabilities, visit:
http://www.xilinx.com/products/spartan6/index.htm.
PCI Express Bus
Description
The FreeForm/Express S6 has a single x1 PCIe express lane, connected directly to the Spartan-6
FPGA. The PCIe interface is facilitated by the Spartan-6’s integrated PCI express endpoint.
Memory & Flash
Description
A single 1024 Mbit x16 DDR3 component (Micron MT41J64M16JT-15E) is connected to the
Spartan-6 FPGA, providing 128 MB of high speed memory. The Spartan-6’s integrated memory
controller provides a generic high speed interface to FPGA logic.
In addition, a 16 Mbit SPI flash component (Numonyx M25P16) is connected to the FPGA’s user
I/O for storage of embedded processor code.
Low Pin Count FMC Interface
Description
The FreeForm/Express S6 provides a single Low Pin Count FPGA Mezzanine Card (FMC) Interface.
The LPC connector provides the following features
36 LVDS pairs, 2 designated as global clocks (or 68 2.5V LVCMOS pairs)
I2C interface
1 SERDES TX / RX channel (Rocket I/O , GTP), with clock
Power : +12VDC, +3.3V DC, +2.5V DC
The FreeForm/Express S6 LPC implementation differs from the VITA 57.1 specification as follows:
VADJ is fixed to +2.5 V DC
Only LVDS or 2.5V LVCMOS I/O is supported.

Configuration
The FreeForm/Express S6 is designed so that the Spartan-6 configuration image is automatically loaded
from the on-board SPI flash at power- up. When a valid configuration is loaded, led D4 is illuminated.
JTAG configuration can be used at any time to program the FPGA.
The FreeForm/Express S6 is fitted with a x4 32 Mbit SPI flash (Winbond W25Q32BVSFIG), which can be
programmed indirectly via JTAG using Xilinx’s IMPACT.
