Section 5. Conclusions
The project has demonstrated that a modular low cost, single chip,
digital power meter can be implemented with the 68HC908LJ12 and a
minimum of external components, mainly discretes. The on-chip 10bit
A/D is used with additional range extension circuits instead of an
external measurement IC, to perform all voltage and current
measurements. The resultant energy calculation is within the
performance specification outlined in IEC61036 specification.
The LJ12 MCU provides a very cost effective solution for a power meter,
as it enables the removal of the energy measurement device and has a
rich set of on chip peripherals that are necessary for metering
applications. The RTC, LCD, ADC, TIM, IRSCI and the EEPROM
emulation routines reduce the external components required and the
software overhead.
The modular design approach enables the hardware and software to be
reused and thus speed up the design cycle for a power meter
development. The schematics, Bill of Material, gerber files and software
are all available to be downloaded from the Motorola website.
