Introduction Document Scope This demo user manual introduces the QM_XC7A35T_SDRAM core board and describes how to setup the core board running with application software Xilinx Vivado 2016.4. Users may employee the on board rich logic resource FPGA XC7A35T-1FTG256C and large SDRAM memory MT48LC16M16 to implement various applications.
Getting Started The QM_XCA35T_SDRAM core board includes below item: Figure 2-1. QM_XC7A35T_SDRAM Top View Below image shows the dimension of the QM_XC7A35T_SDRAM core board: 6.7cm x 8.4cm. The unit in below image is millimeter(mm). Figure 2-2. QM_XC7A35T_SDRAM Core Board Dimension QM_XC7A35T_SDRAM Core Board User Manual V02...
Install Development Tools The QM_XC7A35T_SDRAM core board tool chain consists of Xilinx Vivado 2016.4, Xilinx USB platform cable, XC7A35T core board and 5V DC power supply. Below image shows the Xilinx Vivado 2016.4 development environment which could be downloaded from Xilinx office website: Figure 2-3.
QM_XC7A35T_SDRAM Hardware Design 2.2.1 QM_XC7A35T_SDRAM Power Supply The core board needs 5V DC input as power supply which could be directly injected from power header or the 64P female header U7/U8. Users may refer to the hardware schematic for the detailed design. The on board LED D4 indicates the 3.3V supply, it will be turned on when the 5V power supply is active.
2.2.2 QM_XC7A35T_SDRAM SPI Boot In default, QM_XC7A35T boots from external SPI Flash, detailed hardware design is shown in below figure. The SPI flash is using N25Q064 manufactured by Micron, with 64Mbit memory storage. FPGA_CSO_B 4.7K FPGA_DQ1 FPGA_DQ3 4.7K R234 SO/SIO1 SIO3 FPGA_DQ2 FPGA_CCLK...
2.2.5 QM_XC7A35T_SDRAM Extension IO The core board has two 64P 2.54mm pitch female headers which are used for extending user modules, such as ADC/DAC module, audio/video module, ethernet module, etc. VCCO_34_35 VCCO_34_35 BANK34/35 Voltage BANK35_B7 BANK35_A7 Supply Pins.
