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 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.
