AS1163B SAID2 - Standalone intelligent

driver with 2 RGB channels

1

General description

AS1163B is a mixed signal silicon device optimized for dynamic lighting applications.

The basic purpose of AS1163B is to drive 6 LEDs organized in 2 channel triplets (RGB) with

an independent PWM dimming dynamic range up to 16 bits.

AS1163B

is often addressed with a different name: “SAID2”, an acronym, which stands for

Stand-Alone Intelligent Driver with 2 RGB channels.

Daisy chain configurations of multiple AS1163B devices will enable cost effective

implementation of complex dynamic lighting effects.

AS1163B will support single layer slim PCB designs.

The communication protocol supported by AS1163B is Open System Protocol (OSP), which

makes the SAID2 fully compatible with the ams OSRAM OSIRE E3731i. AS1163B will support

additional features such as I²C gateway, parallel connection, power-rail feedback, analog

readout.

Each AS1163B 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.

AS1163B is with Functional Safety QM and supports to achieve ASIL-B on system level.
