xSPI FPGA Configuration
with Fast Re-Use

Product code: Boot with Fast Re-use

Replace your slow SPI or QSPI flash with a faster or better FPGA fabric configuration device.

This solution employs SLL’s xSPI Multiple Bus Memory Controller (xSPI MBMC). 

xSPI MBMC allows you to select from a wide range of low pin count, faster, or better, configuration devices:

  • 200 MHz DDR x8 xSPI NOR Flash devices from
    Infineon, ISSI, Gigadevice, Macronix and Micron
  • Exciting 200 MHz DDR x8 STT-MRAM from Everspin
    (Nonvolatile memory with PSRAM like performance)
  • 200 MHz DDR x8 Multi-Chip Packages
    (NOR Flash and PSRAM on the same ~12 I/O pins)

This exciting solution will deliver:

  • Far superior memory bandwidth after FPGA fabric configuration
  • Potential to reduce the number of devices and board area in your design

Easy to evaluate on COTS development boards from SLL hardware partners with SLL trial IP.

Fast Chip To Chip Communications

Product code: Chip to Chip Communications

Fast and efficient bidirectional chip to chip communications
over Octa, Octal and xSPI Profile 2.0 PSRAM protocols
       ⚡ High bandwidth
       ⚡ Low latency

Tightly coupled BIDIRECTIONAL communications between:

  • Your chosen ASIC microcontroller unit (MCU) ↔︎ your chosen FPGA
  • Your chosen ASIC microprocessor unit (MPU) ↔︎ your chosen FPGA
  • Your chosen FPGA’s:  FPGA ↔︎ FPGA

Suitable for use with all MCU that have HyperBus compatible memory controllers.

Memory Management and
Memory Protection Solutions

Product code: eMMU eMPU

Significant advances for MMU’s and MPU’s in embedded applications:
