Lichee Tang Nano20K FPGA User Guide

【Introduction】

Tang Nano 20K is a development board, using the GW2AR-18 QN88 FPGA, containing 20736 LUT4 logic cells and 15552 Filp-Flops. There are 2 PLL in this FPGA chip, and many DSP units supporting 18 bit x 18 bit multiplication. Onboard BL616 is used for downloading bitstream into FPGA, and it's also used as USB to serial convertor to communicate FPGA with computer via UART. The 27MHz crystal generates the clock for HDMI display, onboard MS5351 clock generating chip also provides mutiple clocks.
