71M6541D/F/G and 71M6542F/G Data Sheet
1
Introduction
This data sheet covers the 71M6541D (32KB), 71M6541F (64KB), 71M6541G (128KB), 71M6542F
(64KB), and 71M6542G (128KB) fourth generation Teridian energy measurement SoCs. The term
“71M654x” is used when discussing a device feature or behavior that is applicable to all four part
numbers. The appropriate part number is indicated when a device feature or behavior is being discussed
that applies only to a specific part number. This data sheet also covers basic details about the companion
71M6x01 isolated current sensor device. For more complete information on the 71M6x01 sensors, refer
to the 71M6xxx Data Sheet.
This document covers the use of the 71M654x with locally connected sensors as well when it is used in
conjunction with the 71M6x01 isolated current sensor. The 71M654x and 71M6x01 chipset make it
possible to use one non-isolated and one isolated shunt current sensor to create single-phase and two-
phase energy meters using inexpensive shunt resistors, while achieving unprecedented performance with
this type of sensor technology. The 71M654x SoCs also support configurations involving one locally
connected shunt and one locally connected Current Transformer (CT), or two CTs.
