The evaluation systems feature an NXP LPC1100XL series microcontroller, which is designed to handle the communication requirements for intelligent lighting projects using DALI and DMX.
The system includes a master controller board with the LPC11U00, the Cortex-M0 based USB microcontroller.
Both the DALI and DMX512 systems can be connected to any of NXP’s lamp drivers using the PWM outputs of the Cortex-M0 processor. NXP will also offer an optional evaluation system to simplify RGB LED power stage design.
“By bringing Cortex-M0 to lighting control systems using DALI and DMX512, we’re making it straightforward for lighting designers to upgrade from 8-bit microcontrollers without increasing costs,” said Marco Scarazzati, product applications engineer, NXP Semiconductors.
“For DMX networks, the LPC1100XL offers the resources and performance required to support more sophisticated architectural and stage lighting projects,” said Scarazzati.
NXP also offers a small form factor RGB LED power stage with a low component count. The power stage meets the EMC requirements of commercial lighting applications and offers significant energy savings for both DALI and DMX wired lighting control systems.
LED dimming is implemented using the PWM input of the NXP UBA3070 DC-to-DC LED driver, which offers up to 98% efficiency, said the supplier.
