71M6545HT Datasheet Energy Meter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 71M6545T/71M6545HT EVALUATION KIT AVAILABLE Energy Meter ICs.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The 71M6545T/71M6545HT metrology processors are based on Maxim Integrated’s 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 71M6545T/71M6545HT 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 64KB flash and 5KB RAM.

An external host processor can access metrology functions directly through the SPI interface, or alternatively through the embedded MPU core in applications requiring metrology data capture, storage, and preprocessing within the metrology subsystem.
