GOWIN Adopts HyperBus(TM) for built-in PSRAM and HyperRAM (TM) Interfacing

GOWIN Semiconductor Corporation, the world’s fastest-growing programmable logic company, announces HyperBus TM interface specification support for their FPGA and programmable SoC products.  The HyperBus interface is used to support external low pin count memories and the PSRAM provided internally within GOWIN programmable devices.


HyperBus memory provides both high-speed interfacing and low pin count, making it ideal for GOWIN’s edge focused FPGA product lines.  GOWIN devices have up to 64-Mbits of PSRAM with 8-16 bit configurable DDR bus widths directly accessible using GOWIN’s HyperBus Memory Interface IP Core.  Additional external HyperRAM TM and HyperFlash TM memory devices can be connected.  The HyperBus interface consumes only 11 pins and additional memories can be multiplexed using an additional chip select.


GOWIN’s uSoC FPGA’s also provide interfacing support between internal processors, PSRAM, and external HyperRAM, making it ideal for consumer and industrial IoT applications.  Devices such as GOWIN’s LittleBee GW1NSR-2C combine an Arm Cortex M3 microprocessor, FPGA, and a PSRAM in a single device.  The PSRAM is connected to the processor with a HyperBus interface providing 4MB of additional memory internally.  External memories can additionally be added if desired.


“Low pin count memory is essential for the future of embedded semiconductor applications.  While advances in semiconductor technology continually increase the logic gate count in today’s devices, I/O count generally remains constant,” said Grant Jennings, Director of International Marketing for GOWIN Semiconductor,  “As a result, more computing and data traffic have to be transferred over the same number of pins.  GOWIN’s support for HyperBus memory provides efficient usage of its package pins resulting in lower power, cost, and PCB footprint offering compared to solutions using legacy memory alternatives.”


Using HyperBus memory in FPGA applications provides embedded developers with the opportunity to create unique solutions.  Capturing camera or microphone data as well as intermediate layer storage in the HyperBus memory is ideal for Artificial Intelligence and Machine Learning applications.  The memory can also be used as a frame buffer for displays, retaining the last video frame while a system goes to sleep or is rendering new graphics.  The FPGA can also be used to bridge between other processor interfaces such as QSPI or traditional parallel SRAM, where there may be optimization in PCB footprint, layout, or cost.


GOWIN’s HyperBus Memory Interface and PSRAM featured devices are in production now.  Integrated PSRAM is available in both Flash and SRAM product families with package form factors as small as 4.5mm x 4.5mm and FPGA resources from 2K-20K LUTs.
