2.7 CAN
STM3220G-EVAL evaluation board enables two channels of CAN2.0A/B compliant CAN
bus communication based on a 3.3V CAN transceiver on one DB9 connector (CN10). The
two CAN buses can be disconnected by jumpers from relevant STM32F207IGH6 I/Os which
are shared with FSMC and USB OTG HS. Jumpers JP3 and JP10 must be refit to enable
CAN1 or CAN2 as listed in Ta bl e 5 .
High-speed, Standby and Slope Control modes are available and can be selected by setting
jumper JP7.
2.8 RS-232 and IrDA
Both RS-232 and IrDA communication is enabled by D-type, 9-pin RS-232 connectors
(CN16) and IrDA transceiver U11 which are connected to USART3 of STM32F207IGH6 on
STM3220G-EVAL evaluation board.
For ISP support, two signals are added on the RS-232 connector CN16:
●Bootloader_RESET (shared with CTS signal)
●Bootloader_BOOT0 (shared with DSR signal)
RS-232 or IrDA can be selected by setting of JP22 and ISP can be enabled by setting of
jumper JP29 and JP34.

2.9 Motor control
STM3220G-EVAL evaluation board enables a three-phase brushless motor control via a 34-
pin connector (CN5), which provides all required control and feedback signals to and from
the motor power-driving board. Available signals on this connector include 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.
The solder bridge (SB18) allows to choose two kinds of synchronization methods for PFCs
(Power Factor Correction) while the SB17 can be set for different signals on pin 31 of CN5.
The I/O pins used on motor control connector CN5 are multiplexed with some peripherals on
the board; either motor control connector or multiplexed peripherals can be enabled by the
setting of solder bridges SB10, SB11, SB12, SB14, SB15 and SB16.

Smartcard shares some I/Os with I2S bus for Audio. Some jumper settings need to be
reconfigured to enable smartcard as indicated below:
2.11 MicroSD card
The 1 GByte or more MicroSD card connected to SDIO of STM32F207IGH6 is available on
the board. MicroSD card detection is managed by the standard I/O port PH13. MicroSD
card shares I/Os with motor control, RS-232 and audio. The jumpers JP22 and JP16 must
be refit and motor control connector (CN5) must be disconnected for MicroSD card function.
2.12 MEMS
A ST MEMS device LIS302DL is connected to I2C1 bus of STM32F207IGH6 on the board.
2.13 Potentiometer
There is one 10K ohm potentiometer RV1 connected to PF9 of STM32F207IGH6 on the
board.
2.14 ADC
Two test points (TP3 AIN-) and (TP4 AIN+) are placed close to port PC1 of the MCU
allowing precise measurements on ADC1, ADC2 or ADC3 channel 11. As PC1 is also used
as current A input on the motor control connector it is recommended to remove R219 to
optimize noise immunity on this input.
A potentiometer RV1 is connected to PF9 of STM32F207IGH6. If needed, a low pass filter
(R74 and C59) can be placed on this input to reduce the bandwidth of the analog input PF9.
It is also possible to place the Ethernet PHY (U5) in low power mode in order to reduce the
noise induced by this high frequency peripheral. Power down pin (MII_INT in the schematic)
is connected to PB14 of the MCU, so this I/O can be to be configured as output low during
analog precision measurement.

2.15 USB OTG FS
STM3220G-EVAL evaluation board enables USB OTG full speed communication via a USB
Micro-AB connector (CN8) and USB power switch (U1) connected to VBUS. The evaluation
board can be powered by this USB connection at 5V DC with a 500 mA current limitation.
The LED LD6 indicates that the power switch (U1) is ON and STM3220G-EVAL functions as
a USB host or that the VBUS is powered by another USB host while STM3220G-EVAL
functions as a USB device. The LED LD5 indicates an over-current.
2.16 Ethernet
STM3220G-EVAL evaluation board enables 10/100M ethernet communication by a PHY
DP83848CVV (U5) and integrated RJ45 connector (CN7). Both MII and RMII interface
modes can be selected by setting jumpers JP5, JP6 and JP8 as listed below:
Note: 1 A test point (TP2) is available on the board for the PTP_PPS feature test.
2 The Ethernet PHYU5 can be powered down by regulating PB14.

Jumper Description
JP8
JP8 is used to select MII or RMII interface mode.
To enable MII, JP8 is not fitted.
To enable RMII interface mode, JP8 is fitted.
Default setting: Not fitted
JP6
To enable MII interface mode, set JP6 as shown (Default
setting):
To enable RMII interface mode, set JP6 as shown:
JP5
To provide 25 MHz clock for MII or 50 MHz clock for RMII by
MCO at PA8, set JP5 as shown (Default setting):
To provide 25 MHz clock by external crystal X1 (for MII interface
mode only) set JP5 as shown:
When clock is provided by external oscillator U3, JP5 must not be fitted
(Default setting).
SB1
SB1 is used to select clock source only for RMII mode.
To connect the clock from MCO to RMII_REF_CLK, close SB1.
The resistor R212 has to be removed in this case.
Default setting: Open

2.17 USB OTG HS
The STM3220G-EVAL evaluation board enables USB OTG high speed communication via a
USB Micro-AB connector (CN9), USB high speed PHY (U8) and USB power switch (U4)
connected to VBUS. The evaluation board can be powered by this USB connector (CN9) at
5V DC with a 500 mA current limitation.
The LED LD7 indicates that power switch (U4) is ON and STM3220G-EVAL is working as a
USB host or that VBUS is powered by another USB host when STM3220G-EVAL is working
as a USB device. The LD8 indicates an over-current.
The USB ULPI bus is shared with CAN2 bus, the JP10 and JP3 must be kept open for USB
OTG HS.

Jumper Description
JP31 To disable USB OTG PHY U8, JP31 is not fitted.
Default setting: Fitted

2.18 Camera module
A 1.3 megapixel camera module is connected to DCMI bus of STM32F207IGH6 and shares
the same I/Os with the motor control connector. SB16 must be kept open for camera module
application.
Note: 1 When the camera demo loaded in Flash is executed, some green pixels may appear in high
contrast zones, depending on the image captured.
2 The camera is not firmly restricted on its connector (CN15). It is possible that during
shipment the camera could be unplugged. In such case you need to plug it into the right
position as shown on the picture below (pin 1 dot on top left corner of the socket).
It is not recommended to remove it in order to avoid false contact later.
Figure 4. Pin 1 camera plug
The camera extension connector CN23 is available on the boards to connect the ST camera
plug-in board.
Table 13. Camera module related jumpers
Jumper Description
JP26 To set power down mode for the camera module, JP26 is fitted.
Default setting: Not Fitted
SB16 Description of SB16 is in Section 2.9: Motor control.

2.19 SRAM
The 16 Mbit SRAM is connected to FSMC bus of STM32F207IGH6 which shares the same
I/Os with CAN1 bus. JP3 and JP10 must not be fitted for SRAM and LCD application.
2.20 Development and debug support
Version 2 of the ST-LINK, called ST-LINK/V2, is embedded on the board. This tool allows
onboard program loading and debugging of the STM32F using the JTAG or SWD interface.
Third-party debug tools are also supported by the JTAG (CN14) or Trace (CN13)
connectors.
To communicate with the embedded ST-LINK/V2, a specific driver needs to be installed on
your PC. To download and install this driver, refer to the software and development tools
page for the STM32F family available on www.st.com (the install shield is called
ST-LINK_V2_USBdriver.exe).
The embedded ST-LINK/V2 connects to the PC via a standard USB cable from connector
CN21. The bicolor LED LD10 (COM) 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
ST-LINK/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 CN21 (embedded ST-LINK/V2 USB connector)
even if an external tool is connected to CN13 (trace) or CN14 (external JTAG and SWD).
