<p>Tang Nano 20K is a core board using GOWIN Semiconductor GW2AR-18 QN88. The chip has 20736 logical lookup tables (LUT4) and 15552 registers (FF). There are two PLLs inside and multiple units. Supports 18-bit x 18-bit multiplication to number operations.</p> <p>It has built-in low-latency 64Mbits SDRAM, making it easier to run the emulator and better to run soft-core Linux systems.</p> <p>The onboard BL616 chip serves as the FPGA JTAG downloader and serial port for communication with the FPGA.</p> <p>The board uses a 27MHz crystal oscillator by default to multiply the clock required for -compatible display, and is also equipped with an MS5351 clock generation chip to generate a of required clocks at will.</p> <p>The onboard download chip has been upgraded to a USB2.0 interface, with the functions of high-speed JTAG download, serial communication, high-speed SPI reception, and precise clock configuration.</p> <p>color:black</p> <p>Material:PCB+electronic components</p> <p>Package Contents:</p> <p>1 x Tang Nano 20K Core Board</p> <p>1 x data cable</p> <p>2 x PIN</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.</p>
