The AS1130 chip can drive up to 132 LEDs, requiring only 5 mm2 of PCB space, not only reducing the need for external components and PCB layers, but also using inexpensive connectors to extend battery life by 80%.
The driver chip uses 12×11 cross-plexed technology for devices that require dot matrix display for small LED display screens for mobile phones, toys, and personal electronic products. At the same time, it also targets industrial applications such as battery-free home appliances, indoor public information displays, and electric meters. Each product in the AS1130 includes 8-bit dimming control and requires no external resistors. Each array can be fine-tuned to compensate for different color brightness requirements or to adjust the white balance of the RGB LEDs.
In addition, the drive integrates 36 frames of memory for small animations, which can be used as a buffer to reduce the operating load of the main processor, reducing processing time and saving energy. 
[High-tech LED] Austrian Microelectronics, the world's leading designer and manufacturer of high-performance analog ICs, announced the introduction of the most advanced and smallest (channel and PCB space) dot matrix Led Driver chip AS1130.
