AMIS-49200 Fieldbus MAU
Data Sheet
1.0 Introduction
1.1 Overview
AMIS-49200 Fieldbus MAU (media access unit) is a transceiver chip for low speed F
OUNDATION
Fieldbus and Profibus PA devices.
It was designed to be a near pin-for-pin replacement of the Yokogawa
μ
SAA22Q MAU. “Near pin-for-pin” means that associated
component values may change, but no board changes are required.
