71M6545/71M6545H
Metrology Processors
Shunt Resistor Sensors
GENERAL DESCRIPTION
The 71M6545/71M6545H metrology processors are based on
4th-generation metering architecture supporting the 71M6xxx
series of isolated current sensing products that offer drastic
reduction in component count, immunity to magnetic tampering,
and unparalleled reliability. The 71M6545/71M6545H integrate
our Single Converter Technology? with a 22-bit delta-sigma
ADC, a customizable 32-bit computation engine (CE) for core
metrology functions, as well as a user-programmable 8051-
compatible application processor (MPU) core with up to 64KB
flash and up to 5KB RAM.
An external host processor can access metrology functions di-
rectly through the SPI? interface, or alternatively through the
embedded MPU core in applications requiring metrology data
capture, storage, and preprocessing within the metrology
subsystem. In addition, the devices integrate an RTC, DIO, and
UART. A complete array of ICE and development tools,
programming libraries, and reference designs enable rapid
development and certification of meters that meet all ANSI and
IEC electricity metering standards worldwide.
