NORITAKE ITRON VFD MODULES 256 x 64 Dot Graphic is a VFD module with 256x64 dot graphics, single 5V supply, high brightness blue green display, operating temperature -20°C to +70°C, and 11 multi-sized fonts.
The GU256x64D-7000 is a 256 × 64 dot graphic vacuum‑fluorescent display module with high‑brightness blue‑green illumination. It operates from a single 5 V supply, supports temperatures from –20 °C to +70 °C, and includes 11 multi‑sized fonts. The module offers a high‑speed 8‑bit parallel interface compatible with 5 V TTL/CMOS and an asynchronous RS‑232 serial interface up to 115,200 baud.
Electrical specifications list a 5 V DC supply (±4.5 %), typical current draw TBD, and RS‑232 input thresholds of 3.0 V (high) and –15 V (low). Optical specs include a display area of 115.05 × 28.65 mm, dot pitch of 0.3 × 0.3 mm (X) / 0.45 × 0.45 mm (Y), and a luminance of 800 cd/m². The document also provides a set of software command codes for character writing, scrolling, and brightness control.
