TR8253/TR8211 series

The TR8253's chipset is a series of EtherCAT SubDevice Controller chip (including TR8253 and TR8253L), which integrates ESC core module licensed from Beckhoff Automation. It supports 2 or 3 ports of the EtherCAT communication for the EtherCAT SubDevice fieldbus application, and is suitable for industrial automation, motor control, motion control, industrial robot, digital signal I/O control, sensor data acquisition, embodied intelligent robot, and other realtime industrial control product applications.

The TR8253/TR8253L provides two process data interfaces, i.e. μController Local Bus interface and SPI/SQI Slave interface, which can be used for the connection between the TR8253's chipset and external MCU/DSP to support EtherCAT functionality.

The TR8253/TR8253L supports a wide range of applications. For example, it can be used as a 16 bit Digital I/O node without external logic using Distributed Clocks, or as a part of a complex μController design with up to three EtherCAT communication ports.

The TR8253/TR8253L also integrates two current‐mode fast Ethernet PHYs (10/100BASE‐TX), which support 100Mbps full duplex operation and HP Auto‐MDIX functionality. It can also connect to an external PHY via MII to support three-port applications.
