71M6545HT - Energy Meter ICs - 电能测量与计量SoC - Smart Meter AFE Based on Maxim's Fourth-Generation Metering Architecture - 美信半导体
产品概述
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. In addition, the devicesintegrate 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.
The 71M6545T/71M6545HT operate over the industrial temperature range and come in a 64-pin lead(Pb)-free package.
