The range of 128x64 dot format VFD display modules now includes a miniature version developed for compact instrumentation and card reader designs.

The GU128X64C, from Itron UK, uses a high brightness VFD capable of 2.1mm high 5x7 characters which can be read at more than one metre.

Larger built in ASCII fonts provide 4mm and 8mm high characters with the cursor capable of pixel resolution placement allowing applications to make full use of the display area.

The graphic draw and screen editing commands reduce host processing time via the bi-directional asynchronous, SPI and I2C serial interfaces with user selectable 3.3Vdc or 5Vdc logic.

Eight user ports provide onboard key-scan capability for resistive touch and conventional contact switch push buttons on the user front panel.
