[simpits-tech] Solid-state LED matrix help

Once upon a time, I was looking for a display for a 
calculator. A search using an HP part number brought me to 
Avago.

Without knowing the details of the QDSP-2007, a 
"traditional" LED matrix is just that, a LED matrix.
You need to provide drivers for each row/column/segment, and 
refresh the data continuously.

The Avago chips have internal drivers and latches. You write 
the data you want displayed only once, (or only when it 
changes,) and the display's built-in circuitry takes care of 
the rest.  The interface is one bit in into a big shift 
register plus a few control lines.
If the microcontroller uses the same voltage (say, 3.3V) you 
don't need anything more than routing the lines between 
controller and display. (Except, maybe, a few pull up or 
down resistors)
