OM13026,598

OM13026,598 is a DALI NGX Reference Board which contains an example implementation of an isolated physical layer for the Digital Addressable Lighting Interface (DALI) bus with ARM 32bit Cortex M0 LPC111x microcontroller for the DALI protocol handling, and many I/O functions to steer external lighting drivers for solid state or compact fluorescent lighting applications. Up to four PWM signals are available to independently drive different lighting units. Frequency and resolution of the signals is software programmable. DALI systems is capable of achieving lower power consumption and lower cost than those currently available. The reference design can be used as a starting point to develop next generation DALI platforms.

• Reduced system complexity with high performance MCUs
• High efficiency power conversion
• Cost optimized
• Low power consumption from the MCU (for bus power devices)
• Up to four PWM signals available to independently drive different lighting units
• Frequency and resolution of the signals is software programmable
• ON_OFF signal can be used independently from PWM signals to switch lighting driver into OFF/ON state
• I2C bus pins can be used to externally connect other devices like EEPROM or a temperature sensor
• Analog A/D input is available via pin 8
• IO signal is left open for the end user
