1.4 Delivery recommendations
Before using the board for the first time, verify that nothing was damaged during shipment
and that no components are unplugged or lost.
When the board is extracted from its plastic bag, check that no component remains in the
bag.
The main components to verify are:
1. The 8 MHz crystal (X2) which may have been removed from its socket by a shock.
2. The MicroSD card which may have been ejected from the CN8 connector (right side of
the board).
3. The dual-interface EEPROM board (ANT7-M24LR-A) which may have been unplugged
from the CN2 connector (top left corner of the board).

2.1 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated on the STM32091C-EVAL
evaluation board. Compared to ST-LINK/V2 the changes are listed below.
The new features supported on ST-LINK/V2-1 are:
• USB software re-enumeration
• Virtual com port interface on USB
• Mass storage interface on USB
• USB power management request for more than 100mA power on USB
This feature is no more supported on ST-LINK/V2-1:
• SWIM interface
For all general information concerning debugging and programming features common
between V2 and V2-1 refer to ST-LINK/V2 User Manual UM1075.
Note: It is possible to power the board via CN12 (Embedded ST-LINK/V2-1 USB connector) even
if an external tools is connected to CN10 (High density SWD connector) or CN11 (SWD
connector).
2.1.1 Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which can be found on www.st.com for
Windows 7 and 8. On Windows XP the ST-LINK/V2-1 driver requires WinUsb to be installed
before using the ST-LINK/V2-1 (either available from Microsoft website or included in the
USB driver for ST-LINK/V2 for XP).
In case the STM32091C-EVAL evaluation board is connected to the PC before the driver is
installed, some STM32091C-EVAL interfaces may be declared as “Unknown” in the PC
device manager. In this case the user must install the driver files, and update the driver of
the connected device from the device manager.
Note: Prefer using the “USB Composite Device” handle for a full recovery.

2.1.2 ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for in-situ upgrade through the
USB port. As the firmware may evolve during the life time of the ST-LINK/V2-1 product (for
example new functionality, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com before starting to use the
STM32091C-EVAL board and
periodically, in order to stay up-to-date with the latest firmware version.
2.2 Board power supply
STM32091C-EVAL evaluation board is designed to be powered by 5V DC power supply and
to be protected by PolyZen from wrong power plug-in event. It is possible to configure the
evaluation board to use any of the following three sources for the power supply:
• 5V DC power adapter connected to CN16 (the Power jack on the board showed as
PSU on JP15 silkscreen and called E5V). The external power supply is not provided
with the board.
• 5V DC power from CN12 (the USB type B connector of ST-LINK/V2-1, that is showed
as STlk on JP15 silkscreen and called U5V). If the USB enumeration succeeds (as
explained below), the ST-LINK U5V power is enabled, by asserting the PWR_EN pin.
This pin is connected to a power switch (ST890), which powers the board.This power
switch features also a current limitation to protect the PC in case of short-circuit on
board. If over current (more than 600mA) happens on board, the LED LD10 is lit.
• 5V DC power from CN7 (the extension connector for daughter board , that is showed
as D5V on JP15 silkscreen).
STM32091C-EVAL evaluation board can be powered from ST-LINK USB connector CN12
(U5V), but only ST-LINK part has the power before USB enumeration, because host PC only
provides 100mA to the boards at that time. During the USB enumeration, STM32091C-
EVAL board asks for the 300mA power to the Host PC. If the host is able to provide the
required power, the enumeration finishes by a “SetConfiguration” command and then, the
power transistor U23 (ST890) is switched ON, the red LED LD5 is turned ON, thus
STM32091C-EVAL board can consume maximum 300mA current, but not more. If the host
is not able to provide the requested current, the enumeration fails. Therefore the ST890
(U23) remains OFF and the MCU part including extension board won’t be powered. As a
consequence the red LED LD5 remains turned OFF. In this case it is mandatory to use an
external power supply as extra power supply.
E5V (from PSU) or D5V can be used as external power supply in case current consumption
of STM32091C-EVAL board exceeds the allowed current on USB. In this condition it is still
possible to use USB for communication for programming or debugging only, but it is
mandatory to power the board first using E5V or D5V, then connecting the USB cable to the
PC. Proceeding this way ensures that the enumeration succeeds thanks to the external
power source.
The following power sequence procedure must be respected:
1. Connect jumper JP15 for PSU or D5V side
2. Check that JP18 is removed
3. Connect the external power source to PSU or D5V (daughter board mounted)
4. Check red LED LD5 is turned ON
5. Connect the PC to USB connector CN12
Page 12
Hardware Layout and configuration UM1817
12/58 DocID026902 Rev 2
If this order is not respected, the board may be powered by VBUS first then E5V or D5V,
and the following risks may be encountered:
1. If more than 300mA current is needed by the board, the PC may be damaged or
current can be limited by PC. As a consequence the board is not powered correctly.
2. 300mA will be requested at enumeration (since JP18 must be OFF), so there is risk
that request is rejected and enumeration does not succeed if PC can’t provide such
current. Consequently the board is not powered (LED LD5 remains OFF).
Note: In case the board is powered by an USB charger, there is no USB enumeration, so the led
LD5 remains set to OFF permanently and the board is not powered. Only in this specific
case the jumper JP18 needs to be set to ON, to allow the board to be powered anyway.
Figure 5 will help you to understand the structure of the power source on the evaluation
board.

2.3 MCU power modes configuration
Total three power modes are supported on the board, and can be configured by setting the
related jumpers JP5, JP6, JP8, JP9 and JP12 as described in
Tab le 2 and in the below
Notes.
• Mode1: The VDD and VDDA are connected together and powered by fixed 3.3V.
• Mode2: The VDD and VDDA are connected together and powered by adjustable
voltage from 1.65V to 3.6V.
• Mode3: The VDD is powered by adjustable voltage from 1.65V to 3.6V while VDDA is
powered by fixed 3.3V.
Note: JP8 allows current measurement on VDD_MCU. Current measurement is performed by
replacing JP8 by an ammeter.
Note: JP12 allows current measurement on VDDIO2. Current measurement is performed by
replacing JP12 by an ammeter.
Note: JP6 allows to connect analog power source VDD_ANA to the MCU VDDA. JP6 must be
opened (to disconnect VDDA from all analog power VDD_ANA which is connected to
analog circuits on the board) for MCU Idd measurement.
Note: LD8 is lit when VDD<2V and in this case MCU is not functional. LD9 is lit when VDDA<2.4V
and in this case analogue parts in STM32F091VCT6 are not functional.
The LED LD5 is lit when the STM32091C-EVAL evaluation board is powered by the 5V
correctly.
Tab le 3 shows the low voltage limitations that might apply depending on the characteristics
of some peripheral components. Components might work incorrectly when the power level
is lower than the limitation.

Note: The I/O PD11 must be set in open-drain output mode by firmware when working as an HPD
signal control on the HDMI sink connector CN3.
2.18 IR LED and IR receiver
The IR receiver TSOP34836 is connected to PC6 of STM32F091VCT6 and a current
around 100mA on IR LED is driven by PB9 through transistors T4 and T5 on the board.
Note: the IR LED may be driven by PB9 directly with 20mA current when SB20 is closed and
R116 is removed.
2.19 8x USARTs
USART chain could be routed to a 2*8 header so that some jumpers could be used to
connect them in order to demonstrate 8 USART channels in daisy chain.
The data flow is as
showed in the below picture:
Figure 7. USART data flow
At the end both data sent at USART1_TX and data received at USART_RX can be
compared and validated thanks to USARTs chain on CN1.
Warning: USART1/4/8 belongs to VDDIO2 power domain and
USART2/3/5/6/7 belongs to VDDIO power domain, so the
same voltage level for VDDIO and VDDIO2 is needed, to demo
USART chain application on this header.

2.20 Display and Input devices
The 2.4” color TFT LCD connected to SPI1 port of STM32F091VCT6 and 4 general purpose
color LED’s (LD 1,2,3,4) are available as display device. The 4-direction joystick (B3) with
selection key which connected to PA0 and supports wakeup feature. Tamper button (B2) are
also available as input devices.
Note: The bi-directional voltage translator is implemented on SPI MOSI signal between
STM32F091VCT6 and LCD to support 3-wires serial interface of LCD panel only supports 3wire SPI port. The direction of this voltage translator is controlled by IO PE9 (the IO PE15 is
working as MOSI when PE9 is high or as MISO when PE9 is LOW).

3.6 Daughter board extension connector CN6 and CN7
Two 52-pins male headers CN6 and CN7 can be used to connect with daughter board or
standard wrapping board to STM32091C-EVAL evaluation board. All GPI/Os are available
on it. The space between these two connectors and position of power, GND and RESET pin
are defined as a standard which allows developing common daughter boards for several ST
evaluations boards. The standard width between CN6 pin1 and CN7 pin1 is 2700mils
(68.58mm). This is implemented on the majority of evaluation boards.
Each pin on CN6 and CN7 can be used by a daughter board after disconnecting it from the
corresponding function block on STM32091C-EVAL evaluation board. Refer to
Table 21 and
Tab le 22 for details.
