- (W35N01JW, W35N02JW, W35N04JW)
- SLL is performing extensive testing of many device variants in hardware to reduce customer risk
- Supports memory channels running at up to 200 MHz DDR on many FPGA device families
- Supports 2 or more instantiations of memory controller IP in one FPGA design
- You can find a wide range of HyperBus™ and CRUVI Boards from our board partners below.
- Supports Intel FPGA, Microchip FPGA and Xilinx FPGA (see below)
- Is based on SLL’s proven HyperBus Memory Controller (HBMC) IP for HyperBus™ 1.0 devices
- Bundled with the Intel® Cyclone® 10 LP Evaluation Kit sold by Intel here, and by all Intel distributors (Arrow, Digi-Key, Magnica, etc)
- Customers include industrial consortia, high profile government scientific organisations, universities, Fortune Global 500’s down to SME’s around the globe, from USA to China.
- Applications Include commercial and industrial projects and products:
- Sensors, video, visioning, industrial automation, medical, transport, photonics, …
- Transition easily from HyperBus™ 1.0 to HyperBus™ 2.0:
- SLL HyperBus™ 1.0 customers are already successfully employing 200 MHz HyperBus™ 2.0 devices using SLL’s IP

8-, 16-, 32-Bit Datapath
SLL MBMC supports 8-, 16- and 32-bit datapaths
to address a broad range of use-cases, including:
16-bit tightly coupled PSRAM memory channel:
- MBMC 2.0 supports accessing two PSRAM devices in parallel to double the wire speed memory bandwidth
- Ideal for video frame applications
Up to four independent x8 memory channels in one FPGA design:
- Each soft processor core can have its own private memory subsystem for optimal performance and determinism
Interleaved memory access across multiple PSRAM memory channels:
- Create a 16-bit channel using 2 interleaved x8 channels (preliminary support available for AXI4)
- Create a 32-bit channel using 4 interleaved x8 channels (preliminary support available for AXI4)
- Create a 32-bit channel using 2 interleaved x16 channels (under development)
Resources
Developer resources
Please validate your pin-out and board design with Synaptic Labs, your FPGA vendor, and your memory vendors before manufacturing your first prototype.
- Please contact Synaptic Laboratories at info@synaptic-labs.com to validate the memory channel pin-outs for your specific FPGA device before manufacture.
Intel FPGA
MBMC has been ported to several Intel FPGA device families
SLL’s MBMC is many times smaller than any DDRx SDRAM controller IP available for Intel FPGA. Furthermore, x8 HyperRAM requires approximately 3x less pins than x8 DDRx, making it ideal in resource constrained designs.
Memory channel clock speeds:
- Supports full 200 MHz @ 1.8v and 133 MHz @ 3.0v clock speeds on:
- All Cyclone 10 GX, Arria 10, Arria 10 SoC.
- Supports up to 200 MHz @ 1.8V on some Cyclone 10 LP
- Targeting 180-to-200 MHz @ 1.8V on all Cyclone 10 LP devices
- Targeting 180-to-200 MHz @ 1.8V on all MAX 10 devices
- Supports around 140 to 150 MHz @ 1.8V on Cyclone V and Cyclone V SoC
Additional features:
- Automatically configures HyperRAM devices at power on
- Memory devices immediately available for read/write access without a customer boot loader.
- Internal clock-crossing logic to reduce circuit area of customer’s design.
Microchip FPGA
MBMC IP has been ported to Microsemi PolarFire FPGA
SLL is Microchip’s chosen vendor to support up to 200 MHz HyperBus devices on Microsemi PolarFire devices
MBMC IP is complementary to PolarFire’s DDRx solutions:
- Up to 200 MHz memory channel at 1.8V
- Up to 133 MHz memory channel at 3.0V
- Supports AXI4 interface
- Supports GUI configuration in Libero
- Up to 19x less FPGA Logic Elements (LE) than x16 DDR3L controller
- Up to 5x less FPGA I/O pins than x16 DDR3L
- Up to 4x less FPGA I/O pins than x8 DDR3L
- RISC-V software performance on 8-bit HyperRAM @ 200 MHz is highly competitive with 16-bit DDR3 @ 333 MHz
- Automatically configures memory devices at power on
- Immediately available for read/write access without a customer boot loader
- Internal clock-crossing logic to reduce circuit area of customer’s design.
