Product Overview
Product Description
The NCN5120 is the first IC from ON Semiconductor's family of KNX transceivers, handling the transmission and reception of data on the bus. It integrates a 20 V regulator and two high efficient DC-DC converters generating a fixed 3.3 V and a selectable 3.3 to 21 V regulated voltage from the bus with 100 mA drive capability each. This transceiver is ideal for high power applications and has been designed to reduce the bill of materials while supporting safe and reliable coupling to the bus thanks to features such as selectable current slope, bus voltage and temperature monitoring.
Features   Benefits
     
  • KNX certified EIB transceiver with embedded PHY and MAC layers (TP1-256)
 
  • High level of integration, minimal BOM cost
  • KNX communication speed of 9600 Bauds
 
  • Enables high power KNX applications to be connected and supplied from the KNX bus
  • Two high efficient DC-DC converters generating board supply:
    - DC-DC1 : fixed 3.3 V
    - DC-DC2 : adjustable between 3.3 and 21 V
 
  • While designed to offer unique features for most advanced KNX systems, its flexiblity also simplifies integration into legacy designs.
  • 20 V linear regulator
   
  • Configurable fan-in model (up to 2 virtual nodes) and current slopes
   
  • Supervision of KNX bus voltage
   
  • Control and monitoring of the DC-DC converters
   
  • Configurable amount of repetition
   
  • Buffering of sent data frames
   
  • Optional auto acknowledge
   
  • Supports Analog Mode
   
  • Supports Sleep Mode
   
  • Selectable UART/SPI interface and baud rate to Host Controller
   
  • Comprehensive clocking system
    - Operates with industry standard low cost 16 MHz quartz
    - Can generate 8/16 MHz clock for the external MCU
   
  • Operating temperature range -25 C to +85 C
   
  • Household appliances
