Overview
The AMIS-49200-XTD, manufactured by onsemi, is a Fieldbus MAU (Media Access Unit) transceiver chip designed for low-speed FOUNDATION Fieldbus and Profibus PA devices. This component was originally developed as a near pin-for-pin replacement for the Yokogawa µSAA22Q MAU, ensuring that no board changes are required despite potential changes in associated component values. The AMIS-49200-XTD is available in a 44-pin LQFP package and is part of the AMIS-492x0 series, which also includes the AMIS-49250 in a smaller NQFP-44 package.
