This manual describes the programming and configuration features of Gowin GW1N, GW1NS, and GW2A series FPGAs.
The document provides detailed information on programming and configuring Gowin FPGA devices, covering supported configuration modes, pin multiplexing, security considerations, and external SPI Flash usage. It is intended to help users correctly program and configure GW1N(R/S), GW1NS, and GW2A series devices.
The manual includes tables of pin functions, timing diagrams for each configuration mode, instructions for boundary‑scan operations, and guidelines for selecting compatible SPI Flash parts. It also outlines encryption options and dual‑boot procedures where applicable. This manual is written in Chinese.
| Dual‑boot configuration support | GW1N(R/S) series only |
|---|---|
| Required Flash read commands | 03 or 0B |
| Maximum SPI clock frequency for fast read | 80 MHz |
The fast‑read mode can operate up to 80 MHz.
At least one of the commands 03 or 0B must be supported.
