71M6541D

The Maxim Integrated 71M6541-DB REV 3.0 Demo Board is a demonstration board for evaluating the 71M6541 device for single-phase electronic energy metering applications in conjunction with the remote sensor interface. It incorporates a 71M6541 integrated circuit, a 71M6601 remote interface IC, peripheral circuitry such as a serial EEPROM, emulator port, and on-board power supply. A serial-to-USB converter allows communication to a PC through a USB port. The Demo Board allows the evaluation of the 71M6541 energy meter chip for measurement accuracy and overall system use.

The board is preprogrammed with a Demo Program (Demo Code) in the flash memory of the 71M6541F IC. This embedded application is developed to exercise all low-level function calls to directly manage the peripherals, flash programming, and CPU (clock, timing, power savings, etc.).

The 71M6541F IC on the Demo Board is preprogrammed and precalibrated for the 50µΩ or 120µΩ shunt shipped with the board. The Demo Board may also be used for operation with a CT after hardware modifications that can be easily performed by the user. This configuration will require a different version of the Demo Code.
