IST83020B is a USB gaming keyboard chip with multiple backlight modes. This chip supports Fn + F1~F12 key combinations, allowing up to 26-key rollover on a membrane keyboard array, and can also achieve 19-key rollover. IST83020B also supports volume ± functionality with a volume encoder.

In terms of backlight applications, IST83020B is uniquely featured, supporting two single-wire RGB light channels, each with 12 backlight mode options (including synchronous, colorful backlight modes, and reactive modes). Backlight modes can be switched using the Fn + Scr combination keys, and colors can be changed using Fn + Ins.

IST83020B has a built-in RGB LED driver and OSC circuit, enabling the most simplified application circuitry.

IST83020B supports different keyboard arrays based on the Matrix PAD, with three arrays available: IST83020B-01, IST83020B-02, and IST83020B-03.
