Description
The SLG47910V ForgeFPGA provides a small, low-power component for common FPGA applications. Using this device, a circuit design is created by programming the one-time programmable (OTP) non-volatile memory (NVM) to configure the interconnect logic, the IO pins, and the macrocells of the SLG47910V. This highly versatile device allows a wide variety of FPGA applications to be designed within a very small, low-power integrated circuit.
This device is revolutionizing the low-density FPGA space. By combining a robust and well-sorted feature set with low power consumption, low price, and free, easy-to-use development software, the SLG47910V ForgeFPGA opens the door to low-density FPGA development to anyone and everyone.
Benefits
- Ultra-low power consumption for use in even the most demanding wearable and power-constrained applications
- Small package size to allow for tremendous design flexibility
- Advanced 6-input 2-output lookup table (LUT) structure for increased efficiency in high-usage designs
- Low price that opens the low-density FPGA market to customers of all sizes
