hello,
in my application ill use an sd card, therefore im planning to use the internal sd card controller the stm32h743 suggested.
i have some questions, hope you could answer.
- why the EVB uses a dedicated level shifter for sd card, cant you use simple LS Bidirectional ?
- the IP4856CX25/CZ from the EVB is obsolete. the 4857 suggested instead works with host that supports 1.8V level signal, when our controller works from 3.3V only. did you find any replacement to this part for your next EVB manufacturing ?
- in case there is no solution, and there in no similar part and SDR 104 is no longer an option for our controller, do you have another option in with maximum Date rate ? SDR50 maybe?
your advise please
peleg
