MAX6963 Datasheet | Maxim Integrated

Description The MAX6960- MAX6963 are pact cathode-row display drivers that interface microprocessors to 8 x 8 dotmatrix 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 ponents. 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 pensated 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 mand 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.
