STEVAL-IPE023V1: STPMxx programmer
Introduction
This evaluation board is a tool for programming the STPMxxx energy meter ICs family. The
board has been developed to provide an insulated USB interface between a PC and the
STPMxx evaluation boards. The PC runs the GUI to program and read the internal registers
of the energy meter device. The board includes the following sections shown in Figure 1:
• USB interface
• Power management
• Microcontroller

Safety precautions
The board can be connected to a high voltage AC metrology board (D.U.T.) as it offers
galvanic insulation to the digital section. This board is strictly intended for use by expert
technicians. Due to the high voltage (220 VAC) involved, special care must be taken with
regard to personal safety.
There is no protection against accidental human contact with high voltages.
After disconnection of the board from the mains, the live parts must not be touched
immediately due to the energized capacitors.
It is mandatory to use a mains insulation transformer to perform any tests on the board in
which test instruments such as spectrum analyzers or oscilloscopes are used.
Do not connect any oscilloscope probes to high voltage sections in order to avoid damaging
instruments and demonstration tools.
Warning:
1.3
ST assumes no responsibility for any consequences which
may result from the improper use of this tool.
Getting technical support
Technical assistance is provided free to all customers. For technical assistance,
documentation, upgrades and information about products and services, please refer to your
local ST distributor/office.

insulation section for the SPI connector to the energy metrology board being tested.
2.1
Microcontroller
The system is managed by the STM32F103 microcontroller. It is based on the 32-bit ARM
Cortex-M3 core with 72 MHz maximum frequency, 384 KB Flash and 64 KB SRAM
embedded memories; for further details please refer to the STM32F103 high density family
datasheets.
2.2
Debug
Software debug is via a 10-pin JTAG connection; it is possible to use a 10-pin to 20-pin
adapter to use standard 20-pin JTAG tools.

STPMxx programming tool operation
3.1
Normal operation mode
For normal operation, the board implements virtual COM port functionality for PC
communication via USB. Before connecting it to a PC for the first time, install the STM32
Virtual COM Port Driver which is available for download at the following ST web page:
http://www.st.com/internet/mcu/product/216826.jsp.
The board is designed to be used with a dedicated PC GUI for STPMxx energy meter family
ICs. The GUI for STPMC1 evaluation boards is available for download at the following ST
web page: http://www.st.com/internet/evalboard/product/252571.jsp. For more details, refer
to “UM1488: STPMC1 evaluation software”. The GUI for STPM01 evaluation boards is
available for downloading at the ST web page. For more details, refer to user manual
UM1599: The STPM01 and STPM1x evaluation software.
3.2
DFU mode
The board supports firmware upgrade via USB connection. To boot the MCU in DFU mode,
connect (using a jumper) pin 1 and pin 3 of the GPIOs connector; as soon as the board
starts the DFU procedure, LED D3 (Red) turns on. Before running the board in this mode,
you should install the DFU demonstration software on the PC; it is available for download at
the following ST web page: http://www.st.com/internet/mcu/product/216826.jsp. For more
details regarding STM32 DFU functionality, refer to the following user manual: UM0412:
Getting started with DfuSe USB device firmware upgrade STMicroelectronics extension.
The board was tested with version 3.0.2 of the DFU software.
