This document introduces Noritake Itron's VFD modules, including the features and characteristics of the 112x16 dot graphic VFD module, such as single 5V supply, high brightness blue green display, operating temperature range of -40℃ to +85℃, etc. The module includes the Vacuum Fluorescent Display glass, VF drivers, and micro-controller ICs with refresh RAM, character generator, and interface logic. It has 4/8 bit parallel LCD and serial interfaces, and the command set is LCD compatible. The pin assignments for the parallel interface and serial interface of the module are also provided.
The GU112x16G-7806 is a 112 × 16 dot graphic vacuum fluorescent display module with high‑brightness blue‑green illumination. It includes the VFD glass, driver circuitry, a 5 V supply, micro‑controller ICs, refresh RAM, and a character generator, supporting both 4‑bit and 8‑bit parallel as well as serial interfaces.
This document describes the electrical and environmental specifications, the full set of LCD‑compatible and graphic software commands, interface pinouts, font and area commands, and contact information for Noritake Itron sales offices worldwide.
| Display resolution | 112 × 16 dots (2 × 16 characters) |
|---|---|
| Power supply voltage | 5.0 VDC ±5% |
| Power supply current | 250 mA typical |
| Operating temperature | -40 °C to +85 °C |
| Luminance | 700 cd/m² typical |
| Dot size / pitch | 0.33 × 0.575 mm |
| Interface type | 4/8‑bit parallel and serial (SPI/Async) bi‑directional |
| Logic high input (VIH) | 0.8 VDC min |
| Logic low input (VIL) | 0.6 VDC min |
It requires a 5.0 VDC supply with a tolerance of ±5% (VCC) and a 0 V ground reference.
The module supports 4‑bit or 8‑bit parallel interfaces and a serial interface (SPI or asynchronous) that are bi‑directional.
The display operates from –40 °C up to +85 °C.
Brightness is set by a value in the command; 0 = full brightness, 1 = 75 %, 2 = 50 %, 3 = 25 %.
