DB36 Xilinx Virtex-4 LX Daughter Board

Altium's Xilinx® Virtex®-4 daughter board DB36 provides an XC4VLX25-10FF668C device, as well as a range of on-board memories available for use by a design running within that device.

The DB36 has the following features:

• Xilinx Virtex-4 FPGA (XC4VLX25-10FF668C)

• On-board memories available for use by FPGA design:
   
  • 256K x 32-bit common-bus SRAM (1MByte)
  • 16M x 32-bit common-bus SDRAM (64MByte)
  • 16M x 16-bit common-bus Flash memory (32MByte)
  • Dual 256K x 16-bit independent SRAM (512KByte each)
     
• 1-Wire® memory device used to store board ID and related information

• Three 100-way connectors for attachment to NB2DSK01 motherboard. These connectors provide:
   
  • Interface to resources on the NB2DSK01 motherboard and plugged-in peripheral boards
  • SPI bus interface
  • I2C bus interface
  • 1-Wire bus interface
  • JTAG, power and additional control lines from the motherboard.
