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.

Product Detail

The MAX6960 evaluation kit (EV kit) provides a proven design to evaluate the MAX6960 8 x 8 graphic LED tile display driver. The EV kit board contains four MAX6960 LED display drivers, four 2.4in 8 x 8 bicolor LED tiles, a 4MHz oscillator, and logic buffers. Each MAX6960 EV kit can be cascaded to support up to a total of 20 MAX6960 devices. The EV kit also includes Windows® 98SE/2000/XP-compatible software, which provides a simple graphical user interface (GUI) for exercising the MAX6960's features.

The MAX6960 evaluation system (EV system) consists of a MAX6960 EV kit and a companion Maxim CMODUSB serial interface board. The Maxim CMODUSB serial interface board allows an IBM®-compatible PC to use its USB port to emulate a serial interface that is compatible with the MAX6960. Order the MAX6960EVCMODU for a complete PC-based evaluation of the MAX6960. Order the MAX6960EVKIT if you already have a MAX6960 compatible serial interface.

The EV kit includes a preinstalled MAX6960ATH.
