GENERAL DESCRIPTION
The 71M6541D/71M6541F/71M6542F are Teridian’s 4th-generation
single-phase metering SoCs with a 5MHz 8051-compatible MPU core,
low-power RTC with digital temperature compensation, flash memory,
and LCD driver. Our Single Converter Technology with a 22-bit delta-
sigma ADC, three or four analog inputs, digital temperature com-
pensation, precision voltage reference, and a 32-bit computation
engine (CE) supports a wide range of metering applications with
very few external components.
The 71M6541D/71M6541F/71M6542F support optional interfaces to
the Teridian 71M6x01 series of isolated sensors, which offer BOM
cost reduction, immunity to magnetic tamper, and enhanced
reliability. Other features include an SPI interface, advanced
power management, ultra-low-power operation in active and battery
modes, 3/5KB shared RAM and 32/64KB of flash memory that can be
programmed in the field with code and/or data during meter
operation and the ability to drive up to six LCD segments per SEG
driver pin. High processing and sampling rates combined with
differential inputs offer a powerful metering platform for residential
meters.
A complete array of code development tools, demonstration code,
and reference designs enable rapid development and certification of
meters that meet all ANSI and IEC electricity metering standards
worldwide.
