Sercos 3 on AM335x


Design files


The TIDEP0010 Sercos III communication reference design combines the AM335x Sitara processor family and the Sercos III media access control (MAC) layer into a single system-on-chip (SoC) design. Targeted for Sercos III secondary communications, this reference design allows you to implement the real-time Sercos III communication standard for a broad range of industrial automation equipment. The design is based on the TMDSICE3359 industrial communications engine (ICE). This design contains TMDSICE3359, but can also be used with TMDXICE110.

  • Sercos III conformance tested
  • Sercos III firmware for PRU-ICSS with Sercos MAC-compliant register interface
  • Board support package and industrial software development kit available from TI and third party
  • Development platform which includes schematics, BOM, user guides, application notes, white paper, software, demos and more
  • Supports other industrial communications with the same hardware (e.g., EtherCAT, Profinet, Ethernet/IP and more)
