This document describes the features and characteristics of NORITAKE ITRON VFD module GU112x16G-7806AC, including 112x16 dot graphic display, single 5V supply, high brightness blue green display, operating temperature -40°C to +85°C, 3 multi-sized fonts, 5x7 and 10x14 Cyrillic fonts, 4/8 bit parallel LCD and serial interfaces.
The GU112x16G-7806AC is a 112x16 dot graphic VFD module with 4/8‑bit parallel and asynchronous/synchronous serial interfaces. It operates from a 5 V supply, offers high‑brightness blue‑green illumination, and works in temperatures from –40 °C to +85 °C. Electrical, optical and environmental specifications are listed, including a typical luminance of 700 cd/m².
The document describes the LCD‑compatible command set, extended graphic commands, and detailed timing diagrams for parallel and serial communications. It also covers port configuration, reset procedures, and examples for displaying text and graphics on the module.

It requires a 5.0 V DC supply with a tolerance of ±5 %.
Brightness is set with the command 20H + lum where 00H = 100 % (full), 01H = 75 %, 02H = 50 % and 03H = 25 % brightness.
The module supports 4‑bit and 8‑bit parallel LCD‑compatible interfaces as well as asynchronous and synchronous serial interfaces at TTL level.
