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. The asynchronous serial interface accepts baud
rates up to 19,200 with or without parity. Two character font
tables can be hardware or software selected. User defined
characters and many control commands are available.
