XSA-100 Board V1.0 Manual


The XSA-100 Board keeps the same form-factor and attractive pricing of our popular XS40 Boards while increasing the logic density to 100,000 gates with a Spartan-II FPGA.  The Spartan-II is combined with a 16-Mbyte synchronous DRAM to give you the resources for building a complete, soft-core RISC microcontroller system!  Or anything else you might think of...

The bitstream for the XSA-100 can be stored in the on-board 2 Mbit Flash so the FPGA loads its configuration as soon as power is applied.  Or you can download to the board through the parallel port with the XSTOOLs utilities we provide.  The interface CPLD on the XSA-100 can even be programmed so that you can download directly to the board using the XILINX Foundation programming tools!  You can also test and debug your circuits using the XILINX ChipScope software with the XSA-100 and our simple downloading cable.  No more need for expensive MultiLINX cables!

And the XSA-100 helps you maintain your investment.  Use your existing XStend Boards to add a stereo codec, LEDs, switches, and a dedicated prototyping area to the XSA-100.  And keep your power supplies - the XSA-100 has the same power connections as an XS40 Board.

Think it will be a big switch to move from the XS40 Boards to the XSA-100?  Well we provide all the software utilities for programming the FPGA, setting the oscillator frequency, and downloading and uploading the RAM and Flash.  And we make all the source code available for you to play with!  How about design examples?  We have parameterized modules for interfacing to the PS/2 keyboard port, displaying images through the VGA port, and reading/writing to the synchronous DRAM as if it were a simple static RAM.  And we will be adapting all the chapters of our Pragmatic Logic Design online text to support the XSA-100.

The XSA-100: it's not a big change, it's just a bigger board!
