Spartan2Bone

What is this?

• This is prototyping board for Xilinx Spartan-II FPGA processor.
• These circuit mostly simple and easy usage, exclude any test devices.

Features

• This board include features:
  • Xilinx XC2S30 Spartan-II FPGA processor
  • Xilinx XCF01S 1Mbit configuration flash ROM
  • I/O header (IO[1..28], I_GCK[0..3], D[0..7], IRDY[1..2], TRDY[1..2], /WRITE, /CS, BUSY, INIT)
  • JTAG header
  • Mode jumper
  • 3.3V regulator and power configuration jumper

Why Spartan-II now?

• Xilinx Spartan-II FPGA family already deprecated, these processors too old. But Spartan-II has "3.3V operation and 5V torelant I/Os."
• That means, easy usage for "Prototyping by breadboard or likely environments."
• We can get Spartan-II some market (ex: DigiKey). (2017 May)
• Another fit usages, we can use Xilinx XC95 CPLD series. This processors too old and NOT deprecated, but too few macro cells/registers. If you are interesting XC95, try to my project PGA44DIP44.

How to create Spartan2Bone

• Order and get Spartan2Bone PCB.

• Order and get required parts (TODO: parts list)

• Solder Spartan-II
  • Caution!! You must looks direction for Spartan-II! If you missed, repair too hard.

• Solder configuration flash ROM
  • Caution direction too.

• Cleaning by Flux remover.

• Solder other parts.

Sample codes

LedBrink

• Sample for simple LED brink code. (Require Xilinx ISE 10.1)

FizzBuzz

• Sample for FizzBuzz by VerilogHDL. Output by 7seg LED and two Fizz-Buzz LEDs. (Require Xilinx ISE 10.1)
