Audio
An audio codec WM8994ECS/R with 4 DACs and 2 ADCs inside is connected to the SAI
interface of the STM32H743XI microcontroller to support the TDM feature on SAI port. This
feature is able to implement audio recording on digital and analog microphones and audio
playback of various audio streams on headphone and lineout at the same time.
It communicates with STM32H743XI through I2C1 bus which is shared with LCD and MFX
(Multi Function eXpander).
The analog microphone on the headset is connected to the ADC of the WM8994ECS/R
through the audio jack CN17. External speakers can be connected to WM8994ECS/R
through the audio jack CN19.
Two digital microphones (ST-MEMS microphones) MP34DT01TR are on the STM32H743IEVAL Evaluation board. They can be connected to either an audio codec DFSDM or to the
PDM port of the STM32H743XI, by setting the switch SW2 shown in Table 8. The coupon
connectors CN25 and CN26 can be used to support ST-MEMS microphone STEVALMKI129V1 after removing SB54 and SB55 solder bridges.

DocID030511 Rev 1

UM2198

Hardware layout and configuration
A 128-Mbit NOR Flash is connected to the NOR/PSRAM1 bank1 of the FMC interface. The
16-bit operation mode is selected by pull-up resistor connected to the BYTE pin of NOR
Flash. The write protection can be enabled or disabled, depending on how the jumper JP13
is set, as showed in Table 13.
Table 13. NOR Flash related jumpers
Jumper

JP13

Description
Write protection is enabled when JP13 is fitted while write protection is disabled
when JP13 is not fitted.
Default Setting: Not fitted

All signals for memory are also connected on memory connectors CN11 and CN12 for
memory daughterboards.
Limitations can happen when using other peripherals:
1.

FMC addressing limitation depending on number of trace data bus used (A18 max for 4
bit ETM to A21 max for 1 bit ETM)

2.

FMC addresses limited to A18 when SAI used

3.

FMC addresses limited to A22 when PDM is used

In such cases, serial resistors R236 (A19), R231 (A20), R217 (A21) and R230 (A22) should
be removed. Thus memory addresses A19 to A22 are not connected to FMC and they are
pulled down on the board. Memories can be addressed within a limited address range.
By default, all these serial resistors are soldered on the board. If A19 is required, it is
necessary to configure (SAI_SDB) ADCDAT1 pin of audio codec WM8994ECS/R (U22) by
software to be tri-state.

8.17

Twin Quad-SPI NOR Flash
The Quad-SPI Flash is implemented on the STM32H743XI microcontroller of the Evaluation
board either as 1 Twin Quad-SPI NOR Flash (1-Gbit (2*512Mb)) memory or as 2 Quad-SPI
NOR Flash (512Mb) memories.
The two dies in the Twin Quad-SPI Flash memory share the same clock and chip select
signals of the STM32H743XI microcontroller.

8.18

Analog input
The two-pin header CN5 and 10 K ohm potentiometer RV1 is connected to PA0_C of
STM32H743XI as analog input. A low-pass filter can be implemented by replacing R11 and
C7 with the right value of resistor and capacitor as requested by the end-user application.

8.19

Display and input devices
Four general-purpose-color LEDs (LD 1, 2, 3 and 4) are available as display device. LD1

Memory connector CN11 and CN12
Two 40-pin male headers CN11 and CN12 are used to connect with memory
daughterboard.
All GPIOs are connected on the extension connectors CN6 and CN7, but the GPIOs which
are used for FMC memory signals, are connected on CN11 and CN12.
The space between these two connectors is defined as a standard that allows to develop
common daughterboard. The standard width between CN11 pin1 and CN12 pin1 is 1914
mils (48.62 mm). For details on signals assignment refer to Table 25 and Table 26.

Note:1. Text in italic placed on a wire doesn't correspond to net name. It just helps to identify
rapidly MCU IO related to this wire.
2.R100/R103/R107's pull up power is changed from 3V3 to VDD_IO of U13 from A.1 to B.1
3.CAN_RX is connected to PA11 instead of PA9 and CAN_TX is connected to PA12 instead of
PA10 from A.1 to B.1
4.SAI1_MCLKA is connected to PE2 instead of PG7 by default from A.1 to B.1
5.IRDA is removed from A.1 to B.1
6.LEDs' connection are changed, in order to avoid conflict with RGB LCD signals from A.1 to
B.1
7. Updated to STM32H7x3I from B.1 to B.2
