  Unified Fieldbus Controller

The UFC100-L1 (Unified Fieldbus Controller) is a peripheral that can be used in a Fieldbus Device or Host to provide a complete solution for implementing Fieldbus equipment. The UFC100-L1 includes all of time-critical functions in the hardware including address recognition, filtering of received frames, Timer management and Data Link State machine. It implements part of Physical and Data Link Layers for the Foundation Fieldbus H1 and Profibus-PA. The state-of-the-art production process guarantees a longtime availability.
_______________________________________________________
UFC100-L1 replaces UFC100-F1. There is a minor difference in the package. Otherwise, both are identical.

  Area of Application

Fieldbus ASIC for FOUNDATION fieldbus and PROFIBUS PA.The UFC100-L1 is suitable for field devices and controllers.

  Features

RoHS compatible industry standard 44-pin LQFP package
Operating voltage 2.7 to 3.6 V
Low current consumption suitable for Field devices
Flexible 8-bit CPU bus interface suitable for all types of processors
128 byte FIFO can store one frame of most types.



  Enhanced Functions

Filters the received frames and automatically rejects unwanted frames.
