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 (Default – 19200 BPS,
Even Parity, International Font). Two character font tables can
be hardware or software selected.
