AW20108QNR

The AW20108 is a 9×12 matrix LED driver programmed via an I2C compatible interface. The brightness of each LED is independently controlled by FADE and DIM parameter. Three integrated pattern controllers provide auto breathing or group dimming control. Each pattern controller can work in auto breathing or manual control mode. All breathing parameters including rising/falling slope, on/off time, repeat times, min/max brightness and so on are configurable. Each LED’s FADE parameter can sourced from any one of the 3 pattern controllers optionally. Fast display refreshing is supported, multiple parameters(DIM, FADE and PAT) for each LED can be configured together through one I2C write without changing internal page register. 400kHz I2C interface is provided with 4 selectable

addresses by AD pin. Multiple devices clock synchronization can be implemented by configuring the function of pin CLKIO. AW20108 is available in QFN4X4-32L package.
