The Microtronix Avalon Mobile DDR SDRAM Memory Controller IP Core is designed for building high-performance Avalon-MM / Avalon-ST multi-master streaming data systems. Advanced design features enable maximum system clock rates using low speed FPGA's and standard memory devices lowering your production cost, and saving you money.


  • Supports all standard Mobile DDR SDRAM devices
  • 1 to 16 Avalon® independent local bus port interfaces
  • Avalon-MM local bus width from 8 to 128-bits
  • Intelligent SDRAM burst caching controller minimizes wait-states
  • Multiple time domain clocking of ports and memory

Device Utilization and Performance

Device utilization: SDRAM Controller - 700 LE, Avalon Random Port - 500 LE, Avalon Burst Port 500 LEMemory performance: Arria® II GX - 200MHz, Cyclone® IV - 167MHz, Stratix® IV - 200MHz
