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.
