| Unified
Fieldbus Controller |
The UFC100-L2 (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-L2 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.

128
byte FIFO can store one frame of most types. |
|
|
Filters
the received frames and automatically
rejects unwanted frames. |
|
For most frames, only one interrupt
per frame is generated. |
|
Rejected frames do not generate interrupt. |
|
Timer control is in the chip. |
|
Token Timer is automatically loaded
from the received Token. |
|
Many of the state machine transitions
are done in hardware. |
