QM_XC7A35T_SDRAM CORE BOARD
USER MANUAL
Preface
The QMTech® XC7A35T SDRAM core board uses Xilinx Artix®-7 devices to demonstrate the highest
performance-per-watt fabric, transceiver line rates, DSP processing, and AMS integration in a cost-
optimized FPGA. Featuring the MicroBlaze™ soft processor and 1,066Mb/s DDR3 support, the family is the
best value for a variety of cost and power-sensitive applications including software-defined radio, machine
vision cameras, and low-end wireless backhaul.
