2.1 Power supply
STM3220G-EVAL evaluation board is designed to be powered by 5V DC power supply and
to be protected by PolyZen from a wrong power plug-in event. It is possible to configure the
evaluation board to use any of following five sources for the power supply:
●5V DC power adapter connected to JP18, the Power Jack on the board
●5V DC power with 500 mA limitation from CN8, the USB OTG FS Micro-AB connector
●5V DC power with 500 mA limitation from CN9, the USB OTG HS Micro-AB connector
●5V DC power with 500 mA limitation from CN21, the ST-LINK/V2 USB connector
●5V DC power from both CN1 and CN3, the extension connector for daughterboard
(DTB for daughterboard on silkscreen)
The power supply is configured by setting the related jumpers JP4, JP32, JP18 and JP19 as
described inTa b l e 1 .
Table 1. Power related jumpers and solder bridges
Jumper Description
JP4 Jumper reserved for future use (RFU). It should be left open.
Default setting: Not fitted
JP32
MCU_VDD is connected to 3.3V power when JP32 is closed and MCU current
consumption measurement can be done manually by multi-meter when JP32 is
open.
Default setting: Fitted
JP18
JP18 is used to select one of the five possible power supply sources.
To select the ST-LINK/V2 USB connector (CN21) power
supply, set JP18 as shown:
(Default setting)
To select power supply jack (CN18) power supply, set
JP18 as shown:
To select daughterboard connector (CN1 and CN3) power
supply, set JP18 as shown:

Note: The LED LD9 is lit when the STM3220G-EVAL evaluation board is powered by the 5V
correctly.
2.2 Boot option
The STM3220G-EVAL evaluation board is able to boot from:
●Embedded User Flash
●System memory with boot loader for ISP
●Embedded SRAM for debugging
The boot option is configured by setting switch SW1 (BOOT1) and SW2 (BOOT0). The
BOOT0 can be configured also via RS-232 connector CN16.
JP18

To select USB OTG HS (CN9) power supply, set JP18 as
shown:
To select power supply jack (CN18) power supply to both
STM3220G-EVAL and daughterboard connected on CN1
and CN3, set JP18 as shown (daughterboard must not
have its own power supply connected)

2.3 Clock source
Four clock sources are available on STM3220G-EVAL evaluation board for
STM32F207IGH6 and RTC embedded:
●X1, 25 MHz crystal for ethernet PHY with socket. It can be removed when clock is
provided by MCO pin of the MCU
●X2, 26 MHz crystal for USB OTG HS PHY
●X3, 32 kHz crystal for embedded RTC
●X4, 25 MHz crystal with socket for STM32F207IGH6 microcontroller (It can be removed
from socket when internal RC clock is used.)
2.4 Reset source
The reset signal of STM3220G-EVAL evaluation board is low active and the reset sources
include:
●Reset button B1
●Debugging tools from JTAG connector CN14 and trace connector CN13
●Daughterboard from CN3
●RS-232 connector CN16 for ISP
●ST-LINK/V2
2.5 Audio
The STM3220G-EVAL evaluation board enables stereo audio play and microphone
recording by an external headset connected on audio jack CN11. An audio DAC CS43L22 is
connected to both I2S2 port and one DAC channel while a microphone amplifier is
connected to the ADC of STM32F207IGH6. The CS43L22 can be configured via I2C1 and
the external PLL (U36) can be used to provide external clock which is connected to
I2S_CKIN pin (PC9).
