AMIS-49200 Fieldbus MAU Chip
Product Description
IEC-61158-2, H1 (ISA-S50.02-1992), Type 111 and
Type 112 (FF-816) compliant
-40°C to 85°C
44-pin plastic LQFP (Green/RoHS compliant)
Low current consumption: 500A typical
Standard MDS/MAU interface
31.25kbps voltage mode
Dual voltage regulators (3 and 6.2V)
Voltage level monitoring
Key Features
The AMIS-49200 Fieldbus Medium Attachment Unit
(MAU) can be used in applications that meet the
Foundation Fieldbus and Profibus PA standards. It is
compatible with requirements of the IEC-61158-2, H1
(ISA-S50.02-1992, EN 50170 (formerly DIN 19245))
physical layer standard.
The AMIS-49200 Fieldbus MAU is a near pin-for-pin
replacement for Yokogawa SAA22Q. This includes the
elimination of some capabilities and specifications of the
SAA22Q.
In most applications, the AMIS-49200 can be used as a
replacement for the SAA22Q. Some external component
values may have to be changed but, in most cases, the
layout of the circuit board will not have to change.
