Unified Fieldbus Controller provides alternative single-chip solution for device developers
HOUSTON, Texas, February 22, 2007 — The Fieldbus Foundation, conducting
its 2007 General Assembly in Houston, Texas, today announced the
availability of a new fieldbus ASIC for device developers incorporating
H1 (31.25 kbit/s) technology in their field devices and controllers.
Developed jointly by Softing and Aniotek Inc., the UFC100-F1 (Unified
Fieldbus Controller) is a fully pin- and software-compatible
alternative to the Yamaha YTZ420 ("FIND1+") chip.
Conformance, interoperability and physical layer tests were performed
to verify that the UFC100-F1 is a direct replacement for the YTZ420
ASIC. The advantages of the new chip include, but are not limited to,
improved jitter tolerance and a larger first-in/first-out (FIFO)
memory-resulting in fewer interruptions to the field device processor.
According to Dr. Wolfgang Trier, chairman of Softing's management
board, automation equipment suppliers no longer have to rely on the
FIND1+ ASIC as the only non-proprietary, single-chip solution for Foundation
device development. "In our opinion, the lack of alternative
controller products was a liability for fieldbus device developers and
a threat to the technology itself," said Dr. Trier. "Should the FIND1+
chip become unavailable, instrument suppliers using non-proprietary
components would be faced with redesigning many of their fieldbus
devices. For this reason, we decided to come up with a solution that
is fully compatible with the current ASIC configuration."
The Fieldbus Foundation's manager-fieldbus products, Stephen Mitschke,
welcomed the development of the UFC100-F1 chip. "Clearly, the
introduction of this versatile, cost-effective ASIC will benefit the
global fieldbus developer community," said Mitschke. "Instrumentation
designers now have access to a choice of fieldbus ASICs with many
desirable performance characteristics. This will ensure continued
innovation by device developers without the concern of product
The UFC100-FI chip is compliant with the IEC 61158-2 Physical Layer
standard at 31.25 kbit/s, as well as the IEC 61158-4 Data Link Layer
standard. It features integrated digital filter circuits providing a
significantly better noise immunity when compared to the existing ASIC
solution. The chip's low power consumption and wide operating
temperature range make it ideally suited for use in bus-powered H1
devices. Plus, the progressive design of the controller offers
additional functionality for firmware engineers to significantly
enhance future products.
