EtherCAT ASICs ET1100 / ET1200

The ET1100 and ET1200 EtherCAT Slave Controller (ESC) ASICs offer a cost-effective and compact solution for realising EtherCAT slaves. They process the EtherCAT protocol in the hardware and therefore ensure high performance and real-time capability, independent of any downstream slave microcontrollers and associated software. Through their three process data interfaces – digital I/O, SPI and 8/16 bit μC (not for ET1200) – the EtherCAT ASICs enable realisation of simple digital modules without micro-controllers and development of intelligent devices with own processor.

Both ASICs feature distributed clocks that enable high-precision synchronisation (<< 1 μs) of the EtherCAT slaves. The supply voltage is 3.3 V or 5 V; the core voltage of 2.5 V is generated by the integrated in-phase regulator or can be supplied directly. The ET1100 is suitable as a universal solution for all types of EtherCAT devices; the ET1200 is optimised for modular devices using E-bus/LVDS (Low Voltage Differential Signalling) as internal interface. Due to their compact design and small number of external components, both ASICs only require minimum space on the board.
