Low-Cost Two-Phase Electric Meter
TIDM-TWOPHASEMETER-I2040: The design implements a low-cost two-phase electric meter system. This two-chip solution has a metrology processor for calculating metrology parameters and an additional host MCU that has the capability to drive the on-board LCD, add-on communication modules, and USB devices. Isolated communication between the metrology and host MCU is supported by on-board isolators.
Single-Phase Electric Meter with Isolated Energy Measurement
TIDM-METROLOGY-HOST: Electric meter developers often prefer to separate the energy measurement function from the host processor functions such as ANSI/IEC data tables, DLMS/COSEM, tariff management, and communications. This design demonstrates a method for keeping these meter functions separated by using an individual metrology processor and host processor. The firmware supplied with the design manages all of the required functions and synchronization between the processors. The design also demonstrates how to isolate communications between the two processors to achieve the necessary safety requirements. Finally, this design demonstrates a method for meter calibration using the USB interface on an MSP430 MCU. Engineers will be able to more quickly develop smart meters with isolated metrology functions by reusing this reference design.
