8 x 8 Matrix Graphic LED Drivers with 4-Wire Serial Interface Offload Display Tasks from a Microcontroller for Message-Board Applications
SUNNYVALE, CA-August 29, 2005-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX6960-MAX6963 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 are feature-rich LED drivers that offload the display tasks from the microprocessor, simplifying design, reducing software overhead, and improving time-to-market for message board, gaming machine and audio/video equipment applications.
The MAX6960-MAX6963 feature LED fault detection, and provide both analog and digital tile-segment current calibration to allow 8 x 8 displays from different batches. The MAX6963 and MAX6962 drive monocolor displays with two-step intensity control, while the MAX6962 also offers four-step intensity control. The MAX6961 and MAX6960 drive monocolor or RGY displays with two-step intensity control, while the MAX6960 also offers four-step intensity control.
Other driver features include automatic memory-map sharing and allocation between interconnected drivers, factory-trimmed 40mA or 20mA peak segment current, and 256-step panel intensity control. All devices operate at 2.7V to 3.6V and over a -40 degrees Celsius to +125 degrees Celsius temperature range. The MAX6960-MAX6963 are offered in compact, high-heat-dissipation 44-pin QFN and MQFP packages.
The MAX6960-MAX6963 devices are available now at $6.75 (1000-up, FOB USA). Evaluation kits for the MAX6960-MAX6963 are also available.
