Order code
To order the evaluation board based on STM32F446ZE MCU, use the order code
STM32446E-EVAL.
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, it must be checked that no component remains in the bag.
The main components to verify are:
1.
The microSD card which may have been ejected from the CN4 connector (top left
corner of the board).
2.
The dual-interface EEPROM board (ANT7-M24LR-A) which may have been unplugged
from the CN1 connector (top left corner of the board).
Note:1
The plastic protection on the camera should be removed carefully as the connection is very
fragile.
Note:2
For all information concerning the version of the MCU used on the board, its specification
and possible related limitations, visit the ST web site (www.st.com) to download relevant
datasheet and errata sheet.
Warning:
Warning: There is an explosion risk if the battery is replaced
by an incorrect one. Make sure to dispose of used batteries
according to the instructions.

disabled on ST-LINK/V2-1 boards.
Note:
It is possible to power the board via CN16 (Embedded ST-LINK/V2-1 USB connector) even
if an external tools is connected to CN14 or CN15 (SWD connector).
2.1.1
Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which, for Windows XP, 7 and 8, can be
found at www.st.com.
In case the STM32446E-EVAL evaluation board is connected to the PC before the driver is
installed, some STM32446E-EVAL interfaces may be declared as “Unknown” in the PC
device manager. In this case the user must install the driver files, and from the device
manager he must update the driver of the connected device.
Figure 4. Updating the list of drivers in 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 functionalities, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com website, before starting to use the STM32446E-EVAL
board and periodically, in order to stay up-to-date with the latest firmware version.

Hardware layout and configuration
Power supply
STM32446E-EVAL evaluation board is designed to be powered by 5 V 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 five sources for the power supply:
•
5 V DC power adapter connected to CN20 (PSU on silkscreen), the Power Jack on the
board. The external power supply is not provided with the board.
•
5 V DC power with 500 mA limitation from CN9, the USB_OTG_FS Micro-AB
connector
•
5 V DC power with 500 mA limitation from CN8, the USB_OTG_HS Micro-AB
connector
•
5 V DC power with 300 mA limitation from CN16, the ST-LINK/V2 USB
•
5 V DC power from both CN10 and CN12, the extension connector for daughterboard
In case the boards is powered by an external 5V power supply connected to CN20 or CN10
and CN12, this power source must comply with the standard EN-60950-1: 2006+A11/2009,
and must be Safety Extra Low Voltage (SELV) with limited power capability.
The power supply is configured using JP12, JP21 and JP9 as described in Table 2: 32 KHz
crystal Y2 related solder bridges.

DocID027604 Rev 3
UM1871
Hardware layout and configuration
STM32446E-EVAL evaluation board can be powered from ST-LINK USB connector CN16
(U5V), but only ST-LINK part is powered before USB enumeration, because host PC only
provides 100 mA to the boards at that time. During the USB enumeration,
STM32446E-EVAL board asks for the 300 mA 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 U11 (ST890) is switched ON, the red LED LD8 is turned ON, thus
STM32446E-EVAL board can consume maximum 300 mA current, but not more. If the host
is not able to provide such requested current, the enumeration fails, therefore the ST890
(U11) remains OFF and the 3.3 V part of the board will not be powered. As consequence,
the red LED LD8 remains turned OFF. In such 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 STM32446E-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 connect the USB cable to the
PC. Proceeding in this way, ensures that the enumeration succeeds thanks to the external
power source.
The following power sequence procedure must be respected:
1.
Connect jumper JP21 for PSU or D5V side
2.
Check that JP18 is removed (PWR_EXT)
3.
Connect the external power source to CN20 (PSU) or D5V (daughterboard mounted)
4.
Check red LED LD8 is turned ON
5.
Connect the PC to USB connector CN16
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 300 mA 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.
300 mA 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 cannot provide such
current. Consequently the board is not powered (LED LD8 remains OFF).
Note:1
In case the board is powered by an USB charger, there is no USB enumeration, so the led
LD8 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.
Note:2
When the board is powered by ST-LINK, the current is limited by U11 and the LED LD11 is
turned ON in case of over current detection.
2.3
Clock source
Two clock sources are available on STM32446E-EVAL evaluation board for
STM32F446ZET6 and RTC embedded (see Table 2: 32 KHz crystal Y2 related solder

Motor control
STM32446E-EVAL evaluation board supports both asynchronous and synchronous
three-phase brushless motor control via a 34-pin connector CN3, which provides all
required control and feedback signals to and from motor power-driving board. The available
signals on this connector are emergency stop, motor speed, 3-phase motor current, bus
voltage, heatsink temperature, coming from the motor driving board and 6 channels of PWM
control signal, going to the motor driving circuit.
Solder bridges that must be closed for motor control application, are marked in red and are
showed in Figure 7. The solder bridges, that must be opened for motor control application
are: SB85, SB83, SB84, SB19, SB46, SB26, SB38, SB114, SB110 SB111, SB112 and they
are showed in the same Figure 7.
