DB41 Xilinx Spartan-3AN Daughter Board

Frozen Content

Altium's Xilinx® Spartan™-3AN daughter board DB41 provides an XC3S1400AN-4FGG676C device, as well as a range of on-board memories available for use by a design running within that device.

The DB41 has the following features:

  • Xilinx Spartan-3AN FPGA (XC3S1400AN-4FGG676C)
  • 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.
