Question

Please recommend the lowest power MCU supporting the highest SD Card data transfer rate.

Dear ST Support,

  • I am looking for an ultra low power ST MCU supporting
  • the highest data transfer rate on an external SD Card.
  • I also need recommendation on a compatible SD Card Connector to match your recommended MCU.
  • Ultra low power is mandatory because my design is a portable device.

 

Yours faithfully,
Timmy
