The power on rise time should be less than 100ms.The inrush current at power on can be 2 x ICC.

SCROLLING GRAPHIC DISPLAY

The pattern in GRAM can be scrolled around the display. Horizontal scroll is achieved by

increment/decrement of the Display Start X Address. The vertical scroll process considers

layer 0, then layer 1 as a continuous 64 bit high vertical area within RAM.

The module includes the Vacuum Fluorescent Display

glass, driver and control ASIC, with integral refresh Graphic

RAM and logic for parallel and synchronous serial

interfaces. The high speed 8 bit parallel interface is 5V

CMOS compatible suitable for connection to a host CPU

bus. Brightness control and power down functions are

provided. A full data sheet is available.
