Building automation systems based on KNX communication protocols

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
