ON Semiconductor Introduces New Process Automation Transceiver

AMIS-49250 Media Attachment Unit Reduces board size by up to 66%

Process Automation TransceiverPHOENIX, Ariz. – September 30, 2008 – ON Semiconductor (Nasdaq: ONNN), a leading global supplier of high performance, energy efficient, silicon solutions has announced a new product derivative of the AMIS-49200 Media Attachment Unit (MAU). The AMIS-49250 offers additional circuit board space savings of up to 66% compared to the AMIS-49200, and is part of ON Semiconductor’s line of processing automation transceivers for use in safety critical applications such as oil refineries, chemical processing and water treatment plants.

ON Semiconductor has a broad transceiver line and long history of supplying integrated circuits to the automation market (e.g. HART modem). The AMIS-49200 has been a reliable replacement solution for the Yokogawa μSAA22Q MAU device, which is no longer in production. For new designs that cannot accommodate the PCB space required by the μSAA22Q (or AMIS-49200), but require the same functionality, ON Semiconductor has developed the AMIS-49250 in a small, 44-lead NQFP (7x7) (aka MLF, QFN) package.

Similar to the AMIS-49200, the AMIS-49250 complies with the specifications of the IEC-61158-2, H1 (ISA-SP50.02-1992), and EN 50170 physical layer standard, including Foundation Fieldbus H1 and Profibus PA protocols. The device is a physical interface between the bus wiring and the actual measurement device targeting industrial process automation applications, specifically Foundation Fieldbus H1 devices Type 111 and Type 112 per Foundation Fieldbus Specification FF-816 (31.25 kbit/s Physical Layer Profile).

Foundation Fieldbus is an all-digital, two-way communications system intended for use in intrinsically safe sensor-to-computer applications where distribution and transfer of data, integrity of control loops and the ability to integrate dissimilar control systems are essential. Typical applications include closed-loop continuous control, batch sequencing, high-speed process automation, information integration, recipe management, data gathering, legacy system integration, and network integration.

“This new, smaller footprint derivative gives customers more choices when they are in the board design stage, especially when it comes to applying the same AMIS-49200 functionality in a much tighter space,” said Paul Pulley, ON Semiconductor process automation product manager, “The AMIS-49250 delivers all the benefits of an integrated solution combined with smaller form factor and the same unit cost as the AMIS-49200.”

Pricing and Availability
The AMIS-49250 is available through local distribution and is priced at approximately $13.78 USD per unit in 500 unit quantities.
