1.0 Pitch 2.54
The module includes the Vacuum Fluorescent Display
glass, driver and micro-controller ICs with refresh RAM,
character generator and interface logic.
The high speed 8 bit parallel interface is 5V CMOS
compatible suitable for connection to a host CPU bus
which can be set to M68 or i80 series interface by a solder
link on the module. Brightness control and power save
functions are provided. Please call for a full data sheet.
