IS32CS8979 - 18-channel LED drivers

Datasheet Summary

Description

IS32CS8979 combines MCU function and 18-channel LED drivers for applications in the automotive environment such as ambient lighting, dome lighting, and other lighting functions.

MCU includes a 1T 8051 core with enhanced DSP function.

Features

  • of the LED drivers include blink functions and 8-bit dot correction for each channel for accurate RGB color mixing. It also provides fault detection such as LED open/short detections as well as thermal roll-off and shutdown. IS32CS8979 can be controlled and programmed with various host interfaces such as PWM duty, I2C slave, UART/LIN, and SPI. With a built-in MCU, IS32CS8979 can perform complex color space conversions and other fancy functions such as pattern animation and other extended functi.

IS32CS8979 GENERAL DESCRIPTION IS32CS8979 combines MCU function and 18-channel LED drivers for applications in the automotive environment such as ambient lighting, dome lighting, and other lighting functions. MCU includes a 1T 8051 core with enhanced DSP function. There are 2KB SRAM and 64KB e-Flash and both have ECC protections for the harsh application environment. There are three watchdog timers each with an independent clock that further enhances the reliable operations of the MCU. The LED driver consists of 18 high voltage PWM modulated constant current sources with each up to 60mA. It can be used for driving individual LED strings or RGB LEDs. The current source can be controlled globally with 5bit precision.
