KNX

Building automation systems based on KNX communication protocols

Communication is becoming essential in complex buildings. For this reason, NXP cooperates with Weinzierl Engineering to offer dedicated components to realize KNX based systems. A professional version of the KNX system B stack is now available on the LPC1200 to allow a jump start with KNX development.

Description

System notes

LPC1100XL and LPC1200 series microcontrollers:

  • Based on the highly energy-efficient ARM® Cortex™-M0 processor
  • Dramatically lower the cost per KNX node in home and building automation networks
  • Cortex-M0 architecture ideally suited for low-complexity end nodes
  • Include up to 128 KB Flash and 8 KB SRAM, and offer highly configurable peripherals
  • Can be powered directly from the DC-DC converter of the KNX twisted-pair transceivers, making bus-powered devices easy to implement
  • With performance levels up to 45 DMIPS, a single MCU delivers the resources required to run a KNX System B stack (up to 65535 nodes), with enough bandwidth available for the end application
  • Reduced time to market – full professional stack available from partners with flexible license models
  • A certified implementation of the KNX System B is available for the LPC1200 from Weinzierl Engineering
  • Product certification easily achievable

Implementation example (OM13042 demo board):

  • Available with the NXP LPC1227 microcontroller and ON Semiconductor’s NCN5120 transceiver, suitable for use in KNX twisted pair networks (KNX TP1-256)
  • Specifically designed to simplify design process with a ready-to-implement, energy-efficient KNX TP solution for applications such as lighting switches and control, HVA control, shutters and occupancy detection
  • Improves power efficiency, reduces development costs, accelerates time to market for KNX applications on ARM Cortex-M0
