Highly Integrated SoC Sets Sights on Automotive Lighting Systems
NOVOSENSE Microelectronics recently unveiled the NSUC1500-Q1, a highly integrated system-on-chip (SoC) designed to meet the demands of modern automotive ambient lighting systems. The NSUC1500-Q1 can be combined with the high-precision NSLxxxxx series of linear LED drivers for use in automotive taillights and interior lighting modules, EV charging door indicators, and other RGB/RGBW-based lighting systems requiring compact, efficient, and intelligent control.
At the heart of the NSUC1500-Q1 is a 32-bit Arm Cortex-M3 core with 32 kB of flash, 2 kB of EEPROM, 15 kB of ROM, and dedicated memory for runtime operations. The SoC incorporates four LED driver channels capable of delivering up to 64 mA each, controlled through enhanced 16-bit independent PWM outputs.
A 12-bit ADC, in combination with an integrated temperature sensor and voltage monitoring, enables automatic compensation for LED color shift due to temperature changes or aging. The integrated LIN transceiver and controller support LIN 2.x and SAE J2602 communication standards, with features such as auto-addressing to simplify network setup. The SoC also supports software updates via the ROM-based UDS bootloader without occupying flash memory.
The NSUC1500-Q1, available in QFN-24, SOP8, and HSOP8 packages, supports an operating voltage range from 6 to 28 V.
