Maxim's MAX6960-MAX6963 compact cathode-row display drivers interface microprocessors to 8 x 8 dot-matrix red, green, and yellow LED displays through a high-speed 4-wire serial interface. The four LED driver devices offload the display tasks from the microprocessor, simplifying design for message board, gaming machine and audio/video equipment applications. The devices feature LED fault detection, and provide both analog and digital tile-segment current calibration to allow 8 x 8 displays from different batches. The MAX6962/3 drive monocolour displays with two-step intensity control; the MAX6962 also offers four-step intensity control; MAX6960/1 drive monocolour or RGY displays with two-step intensity control; the MAX6960 also offers four-step intensity control. They operate at 2,7 V to 3,6 V. Other driver features include automatic memory-map sharing and allocation between interconnected drivers, factory-trimmed 40 or 20 mA peak segment current.
