STM32100E-EVAL evaluation board
Introduction
The STM32100E-EVAL evaluation board is designed as a complete development platform
for the STMicroelectronics ARM®Cortex-M3 core-based STM32F100 microcontroller with
HDMI CEC connection, FSMC (Flexible Static Memory Controller), two I2C, three SPI, five
USART, 32 Kbytes of internal SRAM, 512 Kbytes of internal Flash memory and JTAG and
SWD debugging/programming support.
The full range of hardware features on the board helps you evaluate all peripherals
(HDMI CEC, SRAM, motor control, LCD, MicroSD card, serial Flash, EEPROM, temperature
sensor, speaker, IrDA, RS-232, RS-485… etc.) and develop your own applications.
Extension headers facilitate the connection of a daughterboard or wrapping board for your
specific applications.
A ST-LINK/V2 is integrated on the board as an embedded debugger and programmer for the
STM32F100 MCU.

2.1 Development and debug support
Version 2 of the ST-LINK, known as ST-LINK/V2, is embedded on the board. This tool allows
program loading and debugging of the STM32F using the JTAG or SWD interface
Third-party debug tools are also supported by using the JTAG connector (CN7).
A specific driver needs to be installed on your PC for communication with the embedded
ST-LINK/V2. The InstallShield package ST-LINK_V2_USBdriver.exe is available from the ST
website. To download and install this driver, please refer to Software and development
tools page for STM32F family available on www.st.com.
Connect the embedded ST-LINK/V2 to the PC via a standard USB cable from connector
CN13. The bi-color LED LD5 (COM in Figure 3) indicates the status of the communication
as follows:
●Slow blinking Red/Off: At power-on before USB initialization
●Fast blinking Red/Off: After the first correct communication between PC and STLink/V2
(enumeration)
●Red LED On: When initialization between PC and ST-LINK/V2 is successfully finished
●Green LED On: After successful target communication initialization
●Blinking Red/Green: During communication with target
●Green On: Communication finished and OK
●Orange On: Communication failure
Note: Note: It is possible to power the board via CN13 (embedded ST-LINK/V2 USB connector)
even if an external tool is connected to CN7 (external JTAG and SWD).
2.2 Power supply
STM32100E-EVAL evaluation board is designed to be powered by a 5 V DC power supply
and to be protected by PolyZen U18 from damage caused by overvoltage and overcurrent
fault conditions. It is possible to configure the evaluation board to use any of following three
power supply sources:
●5V DC power adapter connected to CN14, the Power Jack on the board (Power Supply
Unit (PSU) in Figure 3, JP13 jumper description in Ta bl e 1 ).
●5V DC power with 500mA limitation from CN13, the ST-LINK/V2 type-B USB connector
(STlk in Figure 3, JP13 jumper description in Table 1).
●5V DC power from both CN8 and CN9, the extension connector for daughterboard
(DTB for Daughterboard in Figure 3, JP13 jumper description in Ta bl e 1 ).
The power supply is configured by setting the related jumpers JP13, JP1 and JP10 as
described in Ta b l e 1 .

Hardware layout and configuration UM1055
8/49 Doc ID 018466 Rev 1
The LED LD6 is lit when the STM32100E-EVAL evaluation board is powered by the 5 V
correctly.
Note: The recommended AC220V to DC5V power adapter is the PSU-5V2A. It is not included with
the board but can be ordered from ST as a separate item. You can also use another
equivalent 5V power adapter (polarity compatible with CN14) to power STM32100E-EVAL
board via the CN14 power jack on the board. To order the recommended power supply, use
the order code: PSU-5V2A.
2.3 Boot option
The STM32100E-EVAL evaluation board is able to boot from:
●Embedded user Flash
●System memory with boot loader for ISP

3.8 Daughterboard extension connectors CN8 and CN9
Two 70-pinmale header connectors CN8 and CN9 can be used to connect with
daughterboard or standard wrapping board to STM32100E-EVAL evaluation board. All
GPI/Os are available on it. The space between these two connectors and position of power,
GND and RESET pins are defined as a standard which allows to develop common
daughterboards for several evaluations boards.
The standard width between CN8 pin1 and CN9 pin1 is 2700 mils (68.58mm). The standard
was implemented on the majority of evaluation boards. Each pin on CN8 and CN9 can be
used by a daughterboard after disconnecting it from the corresponding function block on
STM32100E-EVAL evaluation board. Please refer to Ta b l e 2 0 and Ta b l e 2 1 for more details.
