Audio

An audio codec WM8994ECS/R with 4 DACs and 2 ADCs inside is connected to the SAI interface of the
STM32H7x7XI 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 the STM32H7x7XI 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 STM32H7x7I-EVAL Evaluation
board. They can be connected to either an audio codec DFSDM or to the PDM port of the STM32H7x7XI, by
setting the switch SW2 shown in 

Table 10. Audio related switch and jumper

. The coupon connectors CN25 and

CN26 can be used to support ST-MEMS microphone STEVAL-MKI129V1 after removing SB54 and SB55 solder
bridges.

Description

SW2

Digital microphone is connected to the audio codec when SW2 is set as shown below (Default setting):

Digital microphone is connected to the DFSDM port of STM32H7x7XI when SW2 is set as shown below:

Digital microphone is connected to the PDM port of STM32H7x7XI when SW2 is set as shown below:

JP12

Digital microphone power source is connected to +3.3 V power when JP12 is set as shown below (Default
setting):

Digital microphone power source is connected to MICBIAS1 from WM8994ECS/R when JP12 is set as shown
below:

Note:

I

2

C address of WM8994ECS/R is 0b0011010.

PDM clock is on PE2 and it conflicts with SAI_CLK on PE2 by default. When PDM and SAI functions are used at
the same time, SB57 must be OFF and SB56 must be ON to move SAI_CLK to PG7.

USB OTG1_HS and FS

The STM32H7x7I-EVAL Evaluation board supports USB OTG1:
•

High-speed communication through a USB Micro-AB connector (CN14), USB high-speed PHY (U13) for
high-speed function

•

Full-speed communication through another USB Micro-AB connector (CN16)
