Overview

The Digilent Cmod S6 is a small, 48-pin DIP form factor board built around a Xilinx Spartan 6 LX4 FPGA. The board

also includes a programming ROM, clock source, USB programming and data transfer circuit, power supplies, and

basic I/O devices. There are 46 FPGA I/O signals that are routed to 100-mil-spaced through-hole pins, making the

Cmod S6 well suited for use with solderless breadboards. At just .7" by 2.6" inches, it can also be loaded in a

standard socket and used in embedded systems.

1 Configuration

The FPGA on the Cmod S6 can be configured using the on-board Adept USB interface or from the on-board Quad-

SPI Flash memory. Configuration files can be programmed using Xilinx's ISE 14.2 (or higher) development tools,

using Digilent's Adept system, or using older versions of the Xilinx tools if Adept is also installed. Xilinx's ISE/Impact

programming tool and Digilent's Adept tool will recognize the board and/or FPGA when the board is attached to a

PC using a Type-A to micro-B USB cable.

Xilinx's iMPACT tool and Digilent's Adept can both be used to program the FPGA, and iMPACT can also be used to

program the on-board QSPI Flash. Please refer to the ISE and/or Adept documentation for more information on

using the configuration software.

Cmod S6™ FPGA Board Reference Manual When using Digilent's Adept software for programming, a dialog box available from the Config tab can be used to select a configuraiton file. Pressing the Program button will program the FPGA with the selected file. This may result in a warning that the configuration file was built for an unknown device; however, this warning can be ignored.

The Spansion device supports the standard 4-wire SPI protocol, as well as the newer Quad I/O and Dual I/O protocols at speeds from 50 MHz to 133 MHz, depending on the protocol and command used. For more information on the SPI Flash memory, please see the "S25FL128S and S25FL256S Data Sheet" at www.spansion.com.
