Overview of xSPI MBMC IP support for Infineon memory devices

SLL’s xSPI Multiple Bus Memory Controller IP supports Infineon x8 HYPERRAM 2.0 and Infineon x8 SEMPER NOR Flash. 

Infineon’s HYPERRAM™ 2.0 PSRAM memory, is Infineon’s second generation of high-speed, low-pin-count, low-power, self-refresh Dynamic RAM (DRAM) for high-performance embedded systems requiring expansion memory. HYPERRAM™ 2.0 delivers upto 400 MB/s throughput and supports both HYPERBUS™ and Octal xSPI interfaces that draw upon the legacy features of both parallel and serial interface memories, while enhancing system performance and ease of design, as well as reducing system cost. 

Infineon HYPERRAM 2.0 device variants offer up to 256 Mbit of storage capacity, up to 200 MHz DDR clock speeds, with x8 data path widths.  

Infineon SEMPER™ NOR Flash is Infineon’s latest generation of NOR Flash.  It delivers upto 400 MB/s throughput and supports both HYPERBUS™ (xSPI profile 2.0) and Octal xSPI interfaces (xSPI profile 1.0).  The SEMPER™ NOR Flash memory family is Infineon’s high-performance, safe, and reliable NOR Flash solution that integrates critical safety features for a broad range of applications spanning automotive, industrial, communications, and more. With SEMPER™ NOR Flash memory, Infineon delivers the industry’s fi­rst ASIL-B compliant and ASIL-D ready NOR Flash device.

SLL’s is Infineon’s official partners for memory controller IP.  SLL works closely with Infineon to ensure SLL’s memory controller is physically qualified with many Infineon memory device variants, significantly reducing your project’s risks.

SLL’s small MBMC IP enables you to easily evaluate, select and adopt the benefits of Infineon’s latest memories in your projects and products.

SLL provides world class pre-sales and post-sales technical support for Infineon and all the major memory FPGA vendors, helping you navigate the rapidly evolving market, on the platform of your choice.

Get to market faster, with lower power consumption, lower pin count, lower cost, and far lower project risk by using SLL’s memory controller in your project/s with Infineon’s memory devices.

xSPI MBMC Capabilities

  • Includes tight integration with all the major FPGA vendor’s graphical system integration tools (Platform Designer, Vivado, …)  
  • Features high quality local interconnect, with support for the following interconnect protocols:
    • ARM AMBA AXI4 protocol
    • ARM AMBA APB3 protocol
    • Intel Avalon-MM protocol
    • other interconnect protocols available on request…
  • Includes internal clock-crossing circuitry between the local bus interconnect and the external memory channel to reduce circuit area and improve the performance of the customer’s design
  • Excellent memory access performance for both latency sensitive and bandwidth intensive applications:
    • The round trip time for read memory transfer requests through the memory controller has been optimized for latency sensitive applications, such as processor cores.
    • The memory controller supports long burst memory transfer requests over the memory channel to sustain high effective memory bandwidth (>90% efficiency of memory channel)
    • Note:  SLL offers a range of cache technologies to significantly increase the performance of  processor cores that do not have internal instruction and/or data caches when accessing external memories.
  • Features low circuit area and low SRAM usages, making SLL’s memory controller viable for use in resource constrained designs. 
  • Includes optional support for automatic configuration of memory devices at power on:
    • FPGA customers typically use the automatic configuration option
    • This dramatically simplifies integration of SLL’s memory controller in customer designs, enabling all firmware to be executed in place from x8 NOR Flash.  
  • Include support for manual configuration of the memory controller and any attached memory devices
    • ASIC customers typically use the manual configuration option
    • ASIC customers can prototype their designs in FPGA with manual configuration option enabled
  • Supports x4, x8 and x16 data path width in a single instantiation of SLL’s memory controller IP
  • Supports 2 or more instantiations of the memory controller IP in one project
    • Preliminary support for splitting AXI4 requests across 2 instances of the memory controller in parallel to double memory bandwidth is now available
