STM32429I-EVAL evaluation board for STM32F429 MCUs
Introduction
The STM32429I-EVAL evaluation board is a complete demonstration and development
platform for STMicroelectronics Arm®Cortex®-M4 core-based STM32F429NIH6
microcontrollers. It features three I2C, six SPI with two muxed full-duplex I2S, SDIO, four
USART, four UART, two CAN, three 12-bit ADC, two 12-bit DAC, one SAI, 8- to 14-bit digital
camera module interface, internal 256+4 Kbyte SRAM and 2-Mbyte Flash memory, USB HS
OTG and USB FS OTG, Ethernet MAC, FMC interface, JTAG debugging support. This
evaluation board can be used as a reference design for user application development but it
is not considered as a final application.
The full range of hardware features on the board helps the user to evaluate all peripherals
(such as USB OTG HS, USB OTG FS, Ethernet, motor control, CAN, microSD™ card,
USART, Audio DAC and ADC, digital microphone, IrDA, CAN, RF-EEPROM, SRAM, NOR
Flash memory, SDRAM, 4.3" TFT LCD with a resistive touch panel, and others) and develop
his own applications. Extension headers make it possible to easily connect a daughterboard
for specific applications development.
The integrated ST-LINK/V2 provides an embedded in-circuit debugger and programmer for
the STM32 MCU.

4.1 Development and debug support
Version 2 of the ST-LINK (ST-LINK/V2) is embedded on the board. This tool allows on-board
program loading and debugging of the STM32 using a JTAG or SWD interface. Third-party
debug tools are also supported by the JTAG/SWD connector, CN16, and ETM Trace
connector, CN13.
A specific driver must be installed by the user on his PC to communicate with the embedded
ST-LINK/V2. An install shield called ST-LINK_V2_USBdriver.exe is available on the web. To
download and install this driver, refer to the Software and development tools page for
STM32 on www.st.com.
The embedded ST-LINK/V2 is connected to the PC via a standard USB cable connected to
connector CN21. The bicolor LED LD11 (COM) indicates the status of the communication as
follows:
•Red LED slow blinking/Off: At power on before USB initialization
•Red LED fast blinking/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
•Red/Green LED blinking: During communication with target
•Red LED On: Communication finished and OK
•Orange LED On: Communication failure
Note: The board can be powered via CN21 (embedded ST-LINK/V2 USB connector) even if an
external tool is connected to CN13 (ETM trace connector) or CN16 (external JTAG and
SWD connector).
By default ETM only works at 50 MHz clock because ETM signals are shared with other
peripherals.
If best performance of ETM is required (90 MHz), then R29, R32, R34, R36, R40, R114 and
R120 must be removed to reduce the stub on ETM signals. In this case SAI and camera are
not functional and NOR Flash memory and SRAM's addresses are limited on A18.
Caution: When an external high-speed debug tool connected to CN13 or CN16 is used for program
loading or debugging, it is recommended to remove ESD protections D9 to D13 connected
on JTAG signals.

4.8 USB OTG2 HS and FS
The STM32429I-EVAL evaluation board supports USB OTG2:
•High-speed communication via USB Micro-AB connector (CN9), USB high-speed PHY
(U7) for high-speed function
•Full-speed communication via USB Micro-AB connector (CN15)
The evaluation board can be powered by these USB connectors (CN9 or CN15) at 5 V DC
with a 500 mA current limitation.
Some OTG2 FS signals are shared with the OTG2 HS ULPI bus, so some PCB rework is
needed when using OTG2 FS (CN15) as shown in Table 8.
A USB power switch (U6) is connected on VBUS and provides power to either:
•CN9 (with R81 and R97 mounted and R83 and R95 un-mounted)
•CN15 (with R83 and R95 mounted and R81 and R97 un-mounted)
Green LED LD5 (for CN9) or LD9 (for CN15) will be lit when either:
•Power switch (U6) is ON and STM32429I-EVAL is acting as a USB host.
•VBUS is powered by another USB host, and STM32429I-EVAL is acting as a USB
device.
Red LED LD6 is lit if over-current occurs.
4.9 RS-232 and IrDA
RS-232 and IrDA communication is supported by 9-pin RS-232 D-type connector, CN8, and
IrDA transceiver, U1, which is connected to USART1 of the STM32F429NIH6 on the
STM32429I-EVAL evaluation board.

A 2 GB (or more) microSD™ card can be connected to the STM32F429NIH6 SDIO port.
microSD™ card detection is managed by I/O expander GPIO15.
4.11 RF-EEPROM
An RF-EEPROM daughterboard is mounted on CN3 of the STM32429I-EVAL board via the
I2C1 bus. The RF-EEPROM can be accessed by the microcontroller via the I2C1 bus or by
radio frequency (RF) using a 13.56 MHz reader (for example, CR95HF).
The I2C address of RF-EEPROM is 0b1010000.
4.12 CAN
The STM32429I-EVAL evaluation board supports one channel of CAN2.0A/B complaint
CAN bus communication based on 3.3 V CAN transceiver.
High-speed mode, standby mode and slope control mode are available and are selected by
setting JP10.

Jumper Description
JP10
CAN transceiver is working in standby mode when JP10 is set as shown to
the right:
CAN transceiver is working in high-speed mode when JP10 is set as shown to
the right: (default setting)
CAN transceiver is working in slope control mode when JP10 is open.
JP11 CAN terminal resistor is enabled when JP11 is fitted.
Default setting: Not fitted
JP16
PA11 is only connected with USB FS1 DM signal when JP16 is not fitted. (default setting)
PA11 is connected with CAN RX signal when JP16 is fitted.
If the CAN function is being used, USB connector CN14 should be disconnected to leave
USB FS1_DM signal floating.

4.13 Ethernet
The STM32429I-EVAL evaluation board supports 10M/100M Ethernet communication by a
transceiver (U5) and integrated RJ45 connector (CN10). Ethernet PHY is connected to the
STM32F429NIH6 via the MII interface.
A 25 MHz clock can be generated by PHY or provided by MCO from the STM32F429NIH6
by setting jumper JP6 as shown in Table 11.
Note: Ethernet works properly in the default setting (which RX_ER is not connected to PI10 of
STM32F429NIH6) because PI10 is shared with data signal of SDRAM. If RX_ER signal is
needed, remove R244 and solder R43.
4.14 Extension connector
An extension connector (CN2) is intended for external board connection to the STM32429I-
EVAL evaluation board using cable FFSD-05-D-04.00-01-N.
The external board can exchange data with the STM32F429NIH6 via the I2C1 or SPI3
ports.

25 MHz clock for MII is provided by MCO at PA8 when JP5 is set as shown to
the right:
Table 12. Ethernet related solder bridges
Solder bridges Description
SB7 MII CRS on U5 is connected to PA0 when SB7 is closed. PA0 is shared with
Wakeup button and MC_ENA. Default setting: Open
SB8 MII COL on U5 is connected to PH3 when SB8 is closed. PH3 is shared with
SDRAM chip select SDNE0. Default setting: Open
