Overview
AMIS−492x0 Fieldbus MAU (Media Access Unit) is a transceiver chip for low speed FOUNDATION® Fieldbus and Profibus PA devices. The AMIS−49200 was originally designed to be a near pin-for-pin replacement of the Yokogawa mSAA22Q MAU. “Near pin-for-pin” means that associated component values may change, but no board changes are required. A micro-leadframe package option (NQFP) is also available, the AMIS−49250.
