The 71M6543F/71M6543G are 4th-generation polyphase metering systems-on-chips (SoCs) with a 5MHz 8051-compatible MPU core, low-power real-time clock (RTC) with digital temperature compensation, flash memory, and LCD driver. Our Single Converter Technology® with a 22-bit delta-sigma ADC, seven analog inputs, digital metrology temperature compensation, precision voltage reference, and a 32-bit computation engine (CE) supports a wide range of metering applications with very few external components.
The 71M6543F/71M6543G support optional interfaces to the 71M6xx3 series of isolated sensors that offer BOM cost reduction, immunity to magnetic tamper, and enhanced reliability. The ICs feature ultra-low-power operation in active and battery modes, 5KB shared RAM, and 64KB (71M6543F) or 128KB (71M6543G) of flash memory, which can be programmed with code and/or data during meter operation.
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.

Demo Board for the 71M6543F

Features and Benefits

Demo Kit Contents
  • Demo Board DB6543 REV 4.0 with three 71M6203 or 71M6103 ICs and one 71M6543F IC with pre-loaded demo program, or Demo Board DB6543 REV 5.0 with inputs configured for CTs.
  • 5VDC/1000mA universal wall transformer with 2.5mm plug (Switchcraft 712A compatible)
  • USB cable
  • CD-ROM containing documentation (data sheet, board schematics, BOM, layout), Demo Code (sources and executable), and utilities.
  • ANSI base with three 50µΩ shunt resistors, Oswell P/N EBSB20050H-92-19-73-6.4-V1 (optional, for ANSI kits only)
  • Three 120µΩ shunt resistors, Oswell P/N EBSA15120-32-14.8-21-6.2-V1 (optional, for IEC kits)

Product Detail

The Teridian™ 71M6543 REV 4.0 and REV 5.0 demo boards are demonstration boards for evaluating the 71M6543F device for polyphase electronic power-metering applications in conjunction with the remote sensor interface or CT sensors. The demo boards allow the evaluation of the 71M6543F energy meter chip for measurement accuracy and overall system use.
The 71M6543 REV 4.0 demo board incorporates a 71M6543F integrated circuit, three 71M6103 or 71M6203 remote interface ICs, peripheral circuitry such as a serial EEPROM, emulator port, and on-board power supply, as well as a USB interface for serial communication with a PC.
The 71M6543 REV 5.0 demo board is optimized and prepared for the connection of external CTs and is otherwise identical to the REV 4.0 demo board.
All demo boards are preprogrammed with a demo program (demo code) in the flash memory of the 71M6543F IC. This embedded application is developed to exercise all low-level function calls to directly man-age the peripherals, flash programming, and CPU (clock, timing, power savings, etc.).
The 71M6543F IC on the REV 4.0 demo board is preprogrammed and precalibrated for the 50µΩ or 120µΩ shunts shipped with the board. The demo board can also be used for operation with a CT after hardware modifications that can be performed by the user. This configuration will require a different version of the demo code and different settings. It should be noted that the 71M6543 performs better with CTs when used with the 71M6543 REV 5.0 demo board.
