71M6541DT Datasheet Energy Meter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 71M6541DT/71M6541FT/71M6541GT/ 71M6542FT/71M6542GT EVALUATION KIT AVAILABLE Energy Meter ICs.

General Description

The 71M6541DT/71M6541FT/71M6541GT/71M6542FT/ 71M6542GT (71M654xT) are 4th-generation singlephase metering systems-on-chips (SoCs) with a 5MHz, 8051-patible MPU core, low-power RTC with digital temperature pensation, flash memory, and LCD driver.

Our Single Converter Technology® with a 22-bit deltasigma ADC, three or four analog inputs, digital temperature pensation, precision voltage reference, and a 32-bit putation engine (CE) support a wide range of metering applications with very few external ponents.

The 71M654xT devices support optional interfaces to the Maxim Integrated 71M6x01 series of isolated sensors offering BOM cost reduction, immunity to magnetic tamper, and enhanced reliability.

Key Features

  • include an SPI interface, advanced power management, ultra-lowpower operation in active and battery modes, 3KB/5KB shared RAM, and 32KB/64KB/128KB flash.
