Description
The purpose of the demonstration board is to
provide an evaluation platform for the STPMC1
and STPMS2L devices, but it can also be used as
a starting point to design a Class 1 meter for 2 to
4-wire power line systems using delta or wye
service.

The STPMC1 is a metering ASSP implemented
through an advanced 0.35 µm BCD6 technology.

The STEVAL-IPE010V2 board is the motherboard
based on the STPMC1 and works in conjunction
with up to 5 STEVAL-IPE014V1 daughterboards
(to be ordered separately), each with an
STPMS2L mounted to sense the voltage and
current of each phase.

The presence of dedicated networks greatly
reduces the sampling (aliasing) noise and the
crosstalk noise between voltage and current
channels, increasing meter precision. The

The STEVAL-IPE010V2 motherboard receives
the sigma-delta streams from the daughterboards
which are further elaborated by the STPMC1.
This device, from a 4.194 MHz crystal oscillator,
provides a common clock with programmable
frequency to all the daughterboards.

The STEVAL-IPE010V2 motherboard, through a
10-pin flat cable connector, can be interfaced to a
microprocessor board to implement advanced
metering features (multi-tariff, data management
and storage, communication, etc). It also has
stepper motor connectors for simple energy meter
implementation.
