DLP-FPGA-M

Overview

The DLP-FPGA is a compact USB-to-FPGA module designed for rapid prototyping and educational use. It integrates a Xilinx Spartan-3E XC3S250E-4TQ144 FPGA with an FTDI FT2232D dual-channel USB interface IC. The module features a 50-pin, 0.9-inch wide DIP header for external connectivity, on-board 128K x 8 SRAM, and SPI Flash for configuration storage. Powered via USB or external 5V source, it supports Windows, Linux, and Mac OS environments using free Xilinx WebPACK tools.

Feature Summary

• Xilinx Spartan-3E XC3S250E-4TQ144 FPGA with 250K system gates
• FTDI FT2232D Dual-Channel USB Interface (USB 1.1/2.0 compatible)
• Built-in Configuration Loader writes bit files directly to SPI Flash via USB
• On-board 128K x 8 SRAM and 6MHz Clock

Applications

• Rapid Prototyping
• Educational Tool
• Industrial/Process Control

Procurement Notes

Verify the specific revision of the datasheet (Rev. 1.5) when sourcing documentation. Confirm compatibility with required operating systems (Windows, Linux, Mac OS) and ensure availability of the BitLoadApp software utility for direct flash programming. Check for necessary USB drivers from the manufacturer's website.

Selection Notes

Select this module if a low-cost, compact solution for FPGA development is required without external programmers. Ensure the design fits within the 250K gate limit of the XC3S250E. Verify that the 50-pin DIP header interface meets the I/O requirements, noting there are 27 Input/Output channels and 13 Input Only channels available.

Part Context

This module serves as a standalone development platform based on the Xilinx Spartan-3E architecture. It combines the processing power of the FPGA with the convenience of USB connectivity provided by the FT2232D, eliminating the need for parallel port programmers common in earlier FPGA development kits.

Replacement Considerations

For projects requiring higher performance, consider modules featuring newer Xilinx Spartan-6 or Artix-7 families. If only UART functionality is needed without FPGA logic, evaluate the DLP-2232H or DLP-2232ML-G evaluation boards which utilize the same FTDI chip but lack the FPGA component.
