GU280x16G-7002
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 TTL/CMOS compatible suitable for connection to
a host CPU bus. The asynchronous serial interface accepts
baud rates up to 115,200 with none parity. The module is ready
to receive ASCII characters without initialization commands.
