GU140x32F-7006
The module includes the Vacuum Fluorescent Display glass, VF
drivers 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 an
M68 host. The CMOS asynchronous serial interface accepts
baud rates up to 115,200 with none parity. The module is ready
to receive ASCII characters without initialization commands.
