44 PIN LQFP Pin Diagram and Cross-Reference Table
Block Diagram
Differences between the AMIS-49200 Fieldbus MAU and
the Yokogawa SAA22Q are listed in the cross-reference
table.
Pins 11, 22 and 33 may be left N/C, however, we
recommend connecting them to ground to improve noise
immunity.
Pin 39 is the ground for the voltage reference and must
be connected to system ground.
TEST1 – TEST5 must be connected to ground.
The AMIS-49200 was designed to have excellent EMC
performance. In order to achieve the full performance,
VCC Pins 18 and 44 should be connected together.
