1 General description
AS1163 is a mixed signal silicon device optimized for dynamic lighting applications.
The basic purpose of AS1163 is to drive 9 LEDs organized in 3 channel triplets (RGB) with an independent PWM dimming dynamic range up to 16 bits.
AS1163 is often addressed with a different name: “SAID”, an acronym, which stands for Stand-Alone Intelligent Driver.
Daisy chain configurations of multiple AS1163 devices will enable cost effective implementation of complex dynamic lighting effects.
AS1163 will support single layer slim PCB designs.
The communication protocol supported by AS1163 is Open System Protocol (OSP), which makes the SAID fully compatible with the ams OSRAM OSIRE E3731i. AS1163 will support additional features such as I²C gateway, parallel connection, power-rail feedback, analog readout.
Each AS1163 device in the chain will be usable by a MCU to read and write an external I²C device, e.g. EEPROM, temperature sensor, Ambient Light Sensor.
AS1163 is with Functional Safety QM and supports to achieve ASIL-B on system level.
