Introduction
The STM32L4R9I-EVAL board is designed as a complete demonstration and development
platform for the STMicroelectronics Arm
microcontroller with four I²C buses, three SPI and six USART ports, CAN port, two SAI
ports, 12-bit ADC, 12-bit DAC, internal 640-Kbyte SRAM and 2-Mbyte flash memory, two
Octo-SPI memory interfaces, touch-sensing capability, USB OTG FS port, LCD-TFT
controller, MIPI DSI
interface and JTAG debugging support.
The STM32L4R9I-EVAL, shown in
design for user application development before porting to the final product.
The full range of hardware features on the board helps the user to evaluate all the
peripherals (USB, USART, digital microphones, ADC and DAC, TFT LCD, MIPI DSI
display, LDR, SRAM, NOR flash memory device, Octo-SPI flash memory device, microSD™
card, sigma-delta modulators, CAN transceiver, EEPROM) and develop applications.
Extension headers allow easy connection of a daughterboard or wrapping board for a
specific application.
ST-LINK/V2-1 is integrated on the board, as the embedded in-circuit debugger and
programmer for the STM32 MCU and the USB Virtual COM port bridge.

UM2248 Figure 7. MB1314 DSI display daughterboard ST-LINK/V2-1 ST-LINK/V2-1 facility for debugging and flashing of the STM32L4R9AII6 is integrated on the STM32L4R9I-EVAL main board. Compared to the ST-LINK/V2 standalone tool available from STMicroelectronics, ST- LINK/V2-1 offers new features and drops some others. -
Page 19: Drivers
• SWIM interface The USB connector (CN21) can be used to power STM32L4R9I-EVAL regardless of the ST- LINK/V21 facility used for debugging or for flashing STM32L4R9AII6. This holds also when the ST-LINK/V2 standalone tool is connected to the CN12, CN17, CN11, or CN15 connector and used for debugging or flashing STM32L4R9AII6. -
Page 20: Power Supply
16 Mbits. Power supply The STM32L4R9I-EVAL main board must be powered from a 5 V DC power source. It incorporates a precise polymer Zener diode (Poly-Zen) protecting the main board from damage due to the wrong power supply. One of the following four 5 V DC power inputs is usable with an appropriate main board configuration: •... -
Page 21: Supplying The Main Board Through The St-Link/V2-1 Usb Port
100 mA. It is enough because only the ST-LINK/V2-1 part of STM32L4R9I-EVAL draws power at that time. If the SB33 solder bridge is OFF, the ST890 power switch (U22) is set in the OFF position, which isolates the remainder of STM32L4R9I-EVAL from the power source. -

USB port when the excessive current requirement from STM32L4R9I-EVAL is detected. This causes an operating failure to STM32L4R9I-EVAL. The host PC is not capable of supplying 300 mA (the enumeration fails) so ST-LINK/V2- 1 does not supply the remainder of STM32L4R9I-EVAL from its USB port V line. -

Page 26: Audio
There are two digital microphones on the STM32L4R9I-EVAL main board. 6.9.1 Digital microphones U30 and U31 on the STM32L4R9I-EVAL main board are MP34DT01TR MEMS digital omnidirectional microphones providing PDM (pulse density modulation) outputs. To share the same data line, their outputs are interlaced. The combined data output of the microphones is directly routed to STM32L4R9AII6 terminals, thanks to the integrated input digital filters. -
Page 27: Headphones Outputs
The resistor R23 must be left OFF to prevent STM32L4R9I-EVAL from sourcing the 5 V to the terminal, which would cause conflict with the 5 V sourced by the USB host. This might happen if the software of the MFX MCU controls MFX_GPIO6 such that, it enables the output of the power switch (U2). -
Page 28: Stm32L4R9I-Eval Used As A Usb Host
When a USB Device connection to the CN3 Micro-AB USB connector is detected, the STM32L4R9I-EVAL main board starts behaving like a USB Host. It sources 5 V on the V terminal of the Micro-AB USB connector (CN3) to power the USB device. For this to happen, the STM32L4R9AII6 sets the STMPS2151STR power switch (U2) to the ON state. -

Hardware layout and configuration UM2248 I/O ports PB4 and PB5, respectively. The input is accessible on terminal 3 of the jumper header (JP5). On top of the possibility of routing either the potentiometer or LDR to PB4, an external source is connectable to it, using terminal 3 of JP5. The PB5 output of the comparator is accessible on test point TP6. -
