Description

What is Tang Nano 9K?

Tang Nano 9K is an exquisite development board based on the Gowin GW1NR-9 FPGA chip featuring 6480 flip flops and an extended DRAM of 64Mbit. Compared to the predecessor Tang Nano 1K and Tang Nano 4K with about 1152 and 4608 LUTs respectively, Tang Nano 9K has pushed the limits to around 8640 LUT4 logic units. These logic units can not only be used for various complex logic circuit designs but also used for running a complete PicoRV soft-core. It meets various needs of users, such as learning FPGA, verifying softcore, and further design.

This board contains a USB Type-C interface for the power supply and downloading code. There is a  JTAG downloader on the FPGA board, so you can simply use a USB cable connected to the board to download the code without an extra downloader outside the board. 

It is equipped with an HDMI connector, RGB screen interface connector, SPI screen connector, 32Mbit SPI flash, and 6 LEDs. Tang Nano 9K loses the Cortex-M3 core and support for the OV2640 camera, but gains a MicroSD card, more display interfaces, a more complete debugger, and obviously extra logical units. 

Why use Tang Nano 9K to emulate?

  • To make sure the accuracy and reliability of the function of an FPGA chip
  • To shorten the time of launching an FPGA based product and reduce the costs

Please follow the User Guide documentation below to get started with Tang Nano 9K.

Applications

  • Learning FPGA and Verifying an FPGA in Internetwork communication, AI, and Consumer Electronics. 

  • Verifying RISC-V based CPU for server, domestic appliance, Industrial, and thumb-sized sensors.

Matters need attention

  1. It is recommended to use Gowin V1.9.8.03 Education Edition: Click here
    But if you want to use more IP cores, you need to download other versions of IDE, and apply for a license: Click here
  2. This version of a programmer is recommended: Click here
  3. Avoid using JTAG, MODE0/1, and DONE pins. If you really need to use these pins, please refer to the UG284-1.8E: schematic manual.pdf to see how to enable IO mux.
  4. Please avoid static electricity hitting PCBA; Please release the static electricity from the hand before contacting PCBA
  5. The working voltage of each GPIO has been marked in the schematic. Please do not let the actual working voltage of GPIO exceed the rated value, because it will cause permanent damage to PCBA
  6. When connecting FPC flexible cable, make sure that the cable is completely inserted into the cable without offset
  7. Avoid any liquid or metal touching the pads of components on PCBA during working, because this will cause a short circuit and damage PCBA

Tang nano 9K is an exquisite development board based on Gowin GW1NR-9 FPGA chip.It equips with HDMI connector, RGB screen interface connector, SPI screen connector, 32Mbit SPI flash and 6 LEDs, so users can use it for FPGA verification, risc-v soft core verification and basic function verification easily and quickly.
Tang Nano 9K FPGA is the third board from Sipeed based on GOWIN FPGA following the original Tang Nano board with 1K LUT and Tang Nano 4K launched last year with GW1NSR-LV4C (aka GW1NSR-4C) FPGA offering 4068 logical units and 64 Mbit PSRAM, plus an Arm Cortex-M3 hard processor.
Has surprisingly introduced yet another Tang Nano FPGA board based on the Gowin GW1NR-9 chip. This time, the manufacturer has pushed the limits to around 9K (8640) logic units (LUT4), unlike the predecessor Tang Nano 1K and Tang Nano 4K with around 1152 and 4608 LUTs respectively.

RGB LCD display protocol is similar to VGA protocol, both have horizon synchronization signal line and vertical synchronization signal line. The main difference is that RGB LCD display protocol transfers by digital signal while VGA protocol transfers by analog signal.

    This FPGA works as specified and is very useful for a variety of projects. 9K LUTs and several memory types is enough for building a RISC-V SOC with room to spare. And the HDMI output is more useful than a LCD although harder to use. I've used this FPGA for several FPGA projects, implementing various retro CPUs and driving led strips. Note that to use the Gowin IDE you need to obtain a node locked license through the Gowin Website. I'm still trying to figure out how to run verilog testbed simulations on the IDE.
