Infineon Micro Avoids Philips Patent
Infineon has come out with a microcontroller which uses waves in the form of bit-streams to dim and colour-tune LEDs so avoiding Philips’ patent on a technique to dim and colour-tune LEDs using PWM waveforms.
The Infineon microcontroller uses the ARM M0 core.
As well as producing waveforms that set the colour of RGB lighting, the microcontroller can also handle transition curves between different settings and can run DALI or DMX lighting control protocols.
The 32-bit LED controllers XMC1200 and 1300 are part of Infineon’s XMC1000 familyTags: infineon, microcontroller, Philips
