Overview

Quad-SPI Flash memories have many advantages : high speed, low pin count, small packages, and low cost ! ALSE Quad-SPI Flash Controller IP has been designed for ultimate performance, small footprint and easy integration in all kinds of FPGAs, low-cost to high-end. Dramatically reduce the boot time, store streaming video, or even run processor code directly from the Flash, etc. The unique CFI Emulation (optional) feature further facilitates the adoption of Serial Flash memories. Supports all types of Quad SPI Flash Memories. Deliveries include a HDL simulation environment for seamless integration in any project. Our Quad-SPI controller has been used successfully by many customers in different contexts, always delivering outstanding performance.

Features

  • Ultra High Performance. x4, Intelligent controller, Burst mode, supports the Flash maximum speed.
  • Supports almost all devices available, including very high density (devices are added regularly)
  • Supports Flash Programming (modular feature)
  • Unique CFI Flash Emulation (the serial Flash "looks like" a standard parallel NOR Flash)
  • Runs on low-cost FPGAs.

Device Utilization and Performance

Including Flash Programming : ~1,100 LEs, or ~500 ALMs, 1 Memory block Fmax 175MHz on Cyclone III and 230 MHz on Stratix V
