The hardware features are designed to simplify the
software interface and eliminate software timing depen-

A MAX6960 normally drives an 8 x 16 LED matrix, com-
prising 8 cathode rows and 16 anode columns, or
8 anode rows and 16 cathode columns with external
drivers.
The MAX6960 standard wiring connection to either two
monocolor 8 x 8 digits, or to a single RGY 8 x 8 digit is
shown in Table 4. Figure 3 shows the display pin naming.
Figures 1 and 2 show example displays with the
MAX6960 drivers connecting to monocolor and RGY pan-
els. Figure 4 shows how the display memory maps to the
physical pixels on the display panel, provided that the
MAX6960 drivers are interconnected correctly in a raster-
like manner from top left of the panel to bottom right.
The MAX6960 is an LED display driver capable of driving
either two monocolor 8 x 8 cathode-row matrix digits, or a
single RGY 8 x 8 cathode-row matrix digit. The architec-
ture of the driver is designed to allow a large graphic
