New from austriamicrosystems is the AS1119 LED dot-matrix driver. Occupying just 9 mm² of PCB space, the device drives 144 LEDs, each with 8-bit dimming control and no external resistor required. Additionally, an 8-bit analog current control allows fine tuning of each matrix to compensate for different brightness of different colours, or to adjust the white balance on RGB LEDs. The AS1119 incorporates six frames of memory for small animations or for use as a buffer to reduce host processor load. It also includes an on-chip, 320 mA charge pump, allowing continuous operation even under low battery voltage conditions. Other features include control via a 1 MHz I²C compatible interface, open and shorted LED error detection and low-power shutdown current. By employing a technique called cross-plexing, only 18 lines are required to drive all 144 LEDs.
