Microcontrollers With On-Chip EtherCAT For Industrial Applications


To drive real time networked industrial automation and Industry applications, Infineon announced the launch of new XMC4800 series of 32-bit microcontrollers with on-chip EtherCAT (Ethernet for Control Automation Technology) node. EtherCAT is an Ethernet based fieldbus system, invented by Beckhoff Automation. The protocol is standardised in IEC 61158 and is suitable to meet both hard and soft real-time requirements in automation technology.

According to the press release, “The XMC4800 is the first EtherCAT node integrated on an ARM Cortex-M controller with on-chip flash and analog/mixed signal capabilities. The XMC4800 enables the most compact designs, eliminating the need for a dedicated EtherCAT ASIC, external memory and crystal. Designers benefit from BOM cost and PCB space savings. As a member of the XMC4000 microcontroller family with full pin and code compatibility, the XMC4800 is designed to the same high quality and reliability standards as the rest of the family. XMC48000 enables EtherCAT applications in harsh environments with 125°C ambient temperatures. With the integration of the EtherCAT functionality, the XMC4800 enables the most compact design without need for a dedicated EtherCAT ASIC, external memory and clock crystal. It offers a 144-MHz-CPU, up to 2MByte of embedded Flash memory, 352Kbytes of RAM and a comprehensive range of peripheral and interface functions.”

Further in an interview Maurizio Skerlj, Senior Director, Industrial and Multi-market Microcontrollers, Infineon Technologies AG said, “With the XMC4800, very compact system designs with EtherCAT connectivity are possible, as there is no need for a dedicated EtherCAT ASIC, external memory and clock crystal. In combination with its outstanding real-time capability, the XMC4800 series will accelerate the evolution of networked industrial automation.”
