ML9209-xx Overview
The ML9209-xx is an alphanumeric type vacuum fluorescent display (VFD) tube controller driver IC which can display alphanumeric characters, symbols, and bar charts. Vacuum fluorescent display tube drive signals are generated by serial data sent from a micro-controller. A display system is easily realized by internal ROM and RAM for character display.
