  • Reduced system complexity with high performance MCUs
  • High efficiency power conversion
  • Cost optimized
  • Controller side:
    • LPC1100XL microcontroller (up to 50 MHz - 45 DMIPS) offers performance needed to integrate DMX message coding/decoding and PWM generation in a single chip
    • Industry-leading low active power consumption of 110 uA/MHz for bus-powered devices
    • Storage of scene settings in non-volatile memory using EEPROM emulation in flash, or integrated EEPROM in LPC11E00 series
    • Up to four 16-bit and 32-bit timers, generating up to 11 PWM signals to control and dim the ballast
    • Reduced development complexity - software can be written in C
    • Reduced bill of materials – significant cost savings through Cortex-M0 architecture, plus many built-in peripherals to interface with lighting drivers and network in LPC1100XL
  • Power stage:
    • LED dimming using the PWM input of the NXP UBA3070T/N1,118 DC-to-DC LED driver with up to 98% efficiency
    • SSL4101 provides mains isolation for both the RGB LED power stage and the DMX wires
    • Low component count and high efficiency through integrated PFC and flyback control functionality
    • GreenChip TEA1721 buck converter supplies LPC1100XL with high efficiency; no-load power consumption levels
  • Implementation example (DMX512 slave unit):
    • RDM-enabled DMX512 slave or receiver built around the NXP LPC111x Cortex-M0 microcontroller
    • Features four DMX controllable LEDs, a red heartbeat LED, a green traffic LED, DIP switches for selecting the DMX start address, a 5-position joystick, and an optional LCD
    • The UART and the 16-bit timer/counters of the LPC111x MCU are the main hardware blocks needed
    • The I2C hardware block is used to interface with the (optional) LCD functionality
    • References to DMX512 refer to DMX512-A, since both hardware and software are designed using the latest standard
  • Implementation example (DMX512 master unit):
    • DMX512 controller and monitoring device, built around the NXP LPC11U1x microcontroller, enabling Remote Device Management (RDM)
    • Features a USB interface, a red heartbeat LED, and a green traffic LED
    • The USB and UART of the LPC11U1x MCU are the main hardware blocks needed

NXP OM13043,598 DMX512/RDM kit includes a master board and slave board and helps designers create DMX512-based systems for both communication and power stages.

NXP offers dedicated components to realize DMX512 based systems for both communication and power stages. The reference design provides a basic set of commands (including Remote Device Management) that can be used as a starting point to develop next-generation DMX512 platforms.

The DMX512 master is an example implementation for an RDM enabled DMX512 controller and monitoring device, built around the NXP LPC11U1x microcontroller. The DMX512 master features a USB interface, a red heartbeat LED, and a green traffic LED. The USB and UART of the LPC11U1x MCU are the main hardware blocks needed to implement the DMX512 master. The DMX512 master enables Remote Device Management, but the host has to assemble/parse the RDM packets to be sent to/received from the RDM devices connected to the DMX transmission line.

The DMX512 slave or DMX512 receiver is an example implementation for an RDM enabled DMX512 device built around the NXP LPC111x Cortex M0 microcontroller. The DMX512 slave features four DMX controllable LEDs, a red heartbeat LED, a green traffic LED, DIP switches for selecting the DMX start address, a 5-position joystick, and an optional LCD. The UART and the 16-bit timer/counters of the LPC111x MCU are the main hardware blocks needed to implement the DMX512 slave. The I2C hardware block is used to interface with the (optional) LCD functionality.
