Fieldbus ASIC for Field Devices and Hosts Supporting Foundation™ Fieldbus H1 and PROFIBUS PA

The UFC100-L2 fieldbus ASIC implements time-critical parts of the Foundation Fieldbus H1 and PROFIBUS PA communication in field devices or hosts. Its advanced hardware design guarantees functional advantages to UFC100-L2 users. The UFC100-L2 also supports a special Enhanced Mode feature.


Advanced Communication Capabilities

  • Addressing time-critical Physical layer and Data Link layer parts of Foundation Fieldbus H1 or PROFIBUS PA implementations in field devices or host systems
  • Work with additional hardware and software, including additional processor for protocol stack execution as well as Media Attachment Unit
  • Based on state-of-the-art hardware design using CMOS 3.3V technology
  • Advantages like improved jitter tolerance, very low power consumption, and larger FIFO memory with fewer processor interrupts
  • Fully pin-compatible with the Yamaha YTZ420 (“FIND1+”)

Committed to Long-Term Availability and Strict Quality Standards

  • Softing commitment to long-term availability
  • E.g. provision of migration path to current version after discontinuation of predecessor’s package assembly by semiconductor manufacturer
  • Manufacturing and sales using state-of-the-art quality management system complying with ISO 9001:2008
  • Assurance of strict product quality standards by DNV certificate

Enhanced Mode Providing Optimized Communication Features

  • Additional communication functionality in fieldbus controller
  • More CPU power for application software bv reduction of CPU load related to pure bus communication of field device
  • Improved frame handling and increased utilization of bus communication capacity by analyzing incoming messages and rejecting irrelevant ones already at fieldbus ASIC level
