The GW1NS series of FPGA products are the first-generation products in the LittleBee®family and include SoC FPtGA devices and non-SoC FPGA devices. SoC FPFA is embedded with an ARM Cortex-M3 hard core processor, while there is no ARM Cortex-M3 hard core processor in the non-SoC FPGA devices. In addition, the GW1NS series of FPGA products are also embedded with USB2.0 PHY, user flash, and ADC. When the ARM Cortex-M3 hard-core processor is employed as the core, the needs of the Min. memory can be met. FPGA logic resources and other embedded resources can flexibly facilitate the peripheral control functions, which provide excellent calculation functions and exceptional system response interrupts. They also offer high performance, low power consumption, a small number of pins, flexible usage, instant start-up, affordability, nonvolatile, high security, and abundant package types, among other benefits. The GW1NS series of SoC FPFA products achieve seamless connection between programmable logic devices and embedded processors. They are compatible with multiple peripheral device standards and can, therefore, reduce costs of operation and be widely deployed in industrial control, communication, Internet of things, servo drive, consumption fields, etc.

GOWINSEMI provides a new generation of FPGA hardware development environment through market-oriented independent research and development that supports the GW1NS series of FPGA products and applies to FPGA synthesizing, layout, place and routing, data bitstream generation and download, etc.
