Thisdesign was used during initial board verification and some functions are used duringproduction test. It is provided to test out a board if something is not working asexpected. The design files may also be of general interest. The ZIP file has the designsource, a script to run them, and the resulting compiled files.• Programmer for the STMicroelectronics M29DW323DT Parallel NOR Flashwww.xilinx.com/products/boards/s3astarter/reference_designs.htm#parallel_flash_programmerThis design transforms the Spartan-3A or Spartan-3AN FPGA into a programmer forthe 32Mbit STMicroelectronics M29DW323DT parallel NOR Flash memory. Thismemory optionally holds configuration images for the FPGA and provides generalnon-volatile storage for other applications implemented within the FPGA. Using asimple terminal program, this application provides the following capabilities:♦ Erase the memory in part or in full♦ Read the memory to verify contents♦ Download complete configuration images using standard MCS files♦ Manually program individual bytes♦ Display the device identifier and 64-bit unique device numbers• Spartan-3A/3AN “Device DNA” Readerwww.xilinx.com/products/boards/s3astarter/reference_designs.htm#dna_readerThis design uses a PicoBlaze™ processor to read the unique “Device DNA” identifierembedded in each Spartan-3A/3AN FPGA and then display it on the LCD screen.Choose a Spartan-3 Generation Starter Kit Board for your NeedsThe Spartan-3A and Spartan-3AN Starter Kit boards are best for prototypingSpartan-3A/3AN FPGA applications. Depending on specific requirements, however,Xilinx and third-party companies offer development boards that better suit other needs.Spartan-3A/3AN FPGA Features and Embedded Processing FunctionsThe Spartan-3A/3AN Starter Kit board highlights the unique features of the Spartan-3Aand Spartan-3AN FPGA families and provides a convenient development board forembedded processing applications. The board highlights these features:• Spartan-3AN specific features♦ Nonvolatile configuration from internal SPI Flash• Spartan-3A/3AN specific features♦ Parallel NOR Flash configuration♦ SPI serial Flash configuration using either the STMicroelectronics or AtmelDataFlash architectures♦ MultiBoot FPGA configuration from both Parallel NOR and SPI serial FlashPROMs• Embedded development♦ MicroBlaze 32-bit embedded RISC processor
