STPM01/10 single-phase meter demonstration boards
Introduction
The STPM01 and STPM10 devices are energy meter ASSPs (application specific standard
products) designed to address a wide range of electricity metering requirements thanks to
their built-in functions such as signal conditioning, signal processing, data conversion,
input/output signals, and voltage reference.
STPM10 is dedicated for peripheral use only in microcontroller based applications, while
STPM01 is able to work as a peripheral but also as a standalone device, since it can
permanently store configuration and calibration data.
This user manual refers to the following STPM01/STPM10 single-phase meter
demonstration boards:
■
STEVAL-IPE002V1: STPM01 single-phase meter with two CTs
■
STEVAL-IPE003V1: STPM01 single-phase meter with CT and shunt
■
STEVAL-IPE004V1: STPM01 single-phase meter with shunt
■
STEVAL-IPE015V1: STPM10 single-phase meter with two CTs
■
STEVAL-IPE016V1: STPM10 single-phase meter with CT and shunt
■
STEVAL-IPE017V1: STPM10 single-phase meter with shunt
■
STEVAL-IPE018V1: STPM10 single-phase meter with CT.
These metering modules can be used to build a Class 0.5 single-phase standalone or
microprocessor based meter, with or without Tamper detection, for power line systems of

Page 5: Getting Started
UM1082 Getting started Getting started Safety rules This board can be connected to mains voltage (220 V/110 V). In the case of improper use, wrong installation or malfunction, there is a danger of serious personal injury and damage to property. All operations such as transport, installation, and commissioning, as well as maintenance, should be carried out only by skilled technical personnel (national accident prevention rules must be observed). -

Page 11: Communication With The Module
UM1082 Communication with the module Communication with the module 4.0.1 PC communication It is possible to evaluate the metering module and the device features through a dedicated graphical user interface running on a PC. In this case, the module should be connected to the PC through the parallel programmer, shown below, provided with the board plugged in connector P1, taking care that pin 1 of the cable is connected with the right pin on the board, recognizable by the mark printed on the PCB. -

UM1082 The GUI can be downloaded from www.st.com/internet/evalboard/product/123767.jsp. Make sure to power on the measurement module to program the OTP (only for STPM01). This is not necessary to read and write (not OTP write) the RAM inside the device. A serial isolated programmer is also available, with part number STEVAL-IPE005V1. -
