Hello,

14680 datasheet says that is Preliminary but I got the Pro Kit and I see the device is available on market DigiKey, Mouser.
Is 14680 still under preliminary development ?

I look at SPI & QSPI info planning to attach an SD card. What would be the limitations in terms of uSD Card support, speed, reliability ?
From docs I noted 'SPI interface implements a subset of SPI' and on QSPI 'Single mode only allows Mode 0 and 3...'
Could I implement uSD Card via SPI or QSPI with a reliable quality ? What would be the transfer speed you would appreciate ?
Some special things to consider in this case ?

Thank you
