Description

The MSC7128-xx is a general purpose display controller for vacuum fluorescent display tube.

The MSC7128-xx drives displays with up to 35 anodes (dots) and up to 16 grids (characters) plus a cursor.

The controller accepts command and display data input words on a clocked serial input line.

Commands control the on/off duty cycle, starting character position, number of characters to display and display modes (PLA mode and Lamp Test mode). An internal PLA-type character generator provides character decoding and dot pattern generation for the full 128 characters.

A 35 ´ 128-bit PLA (ROM) code is programmable.
