1. Describe
AMIS-49200-XTD 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 SAA22Q 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.
