AMIS-49200 Fieldbus MAU
Overview
AMIS−49200 Fieldbus MAU (Media Access Unit) is a transceiver
chip for low speed FOUNDATION^ Fieldbus and Profibus PA
devices. It was 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.
