Hello,
I want to interface two SAI of STM32L4S7VIT6 with two SGTL5000, which are working as transmitter and receiver at any time as used in telephone. Also interface one Si32287 through PCM. In datasheet SAI1_D1,D2, D3 are given but in reference manual it is not given. Also can we connect for one SGTL5000 with SAI1_FS_A, SAI1_MCLK_A,SAI1_SCK_A,SAI1_SD_A and SAI1_SD_B of same SAI1. And for other SGTL5000, can we connect SAI1_FS_B, SAI1_MCLK_B,SAI1_SCK_B of same SAI1 and for data SDI1_D1 and SDI1_D2. What are the functions of the lines SAI1_D1 and SAI1_D2?
Solved! Go to Solution.

Hi,
one possible chip: H562/3 :
2 SAI + 3 I2S .
Look yourself at the chip selector....many have 3 SAI (H7xx) or 3 I2S (H562/3 ).

Hi,
as i use the H743ZI with 3 SAI /6 ch , working fine : yes, H742VI should be fine for you.
To check avail pins: just make new STM32 project in Cube, for H742VI , select all you need in Cube, like debug, uart, SAI x3 , both blocks , for rx+tx , etc. Then check if possible on 100pin package, as you choose, with all peripherals you want set as active.

Thank you AScha.3 for confirming that the STM32H742VIT6 should work for our application.
We’ll proceed to verify the pin availability and peripheral configuration in STM32CubeMX as you suggested.
Appreciate your support and guidance.

@AScha.3 ouch, my bad, codec has 4 channels.
