New ASIG: 2nd source FOUNDATION fieldbus chip available

By Control Engineering Staff March 15, 2007

The Fieldbus Foundation announced availability of a new fieldbus ASIC for device developers incorporating FOUNDATION H1 (31.25 kbit/s) technology in 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. It’s the second H1 chip available.
