The MAX6960–MAX6963 are compact cathode-row display
drivers that interface microprocessors to 8 x 8 dot-matrix
red, green, and yellow (R,G,Y) LED displays
through a high-speed 4-wire serial interface.
The MAX6960–MAX6963 drive two monocolor 8 x 8
matrix displays, or a single RGY 8 x 8 matrix display with
no external components. The driver can also be used
with external pass transistors to control red, green, blue
(RGB) and other displays at higher currents and voltages.
The MAX6960–MAX6963 feature open- and short-circuit
LED detection, and provide both analog and digital tile
segment current calibration to allow 8 x 8 displays from
different batches to be compensated or color matched.
A local 3-wire bus synchronizes multiple interconnected
MAX6960–MAX6963s and automatically allocates memory
map addresses to suit the user's display-panel
architecture.
The MAX6960–MAX6963s' 4-wire interface connects multiple
drivers, with display memory mapping shared and
allocated among the drivers. A single global write operation
can send a command to all MAX6960s in a panel.
The MAX6963 drives monocolor displays with two-step
intensity control. The MAX6962 drives monocolor displays
with two-step or four-step intensity control. The MAX6961
drives monocolor or RGY displays with two-step intensity
control. The MAX6960 drives monocolor or RGY displays
with two-step or four-step intensity control.
