TS3A27518E-Q1: Can I use 2x 6 bit 2:1 devices to support octal SPI communication between flash memory and SOC?

e2e, 

Would you please recommend an appropriate 2:1 Mux product to meet the use case as diagram below?

I'm searching for 2:1 Mux with multiple channels to support octal SPI communication between flash memory and SOC. 

Any other devices you recommend that can be automotive qualified will be helpful. 

Thank you, 

Adam

    Hi Adam,

    We have a couple of options for the application

    First the TS3A27518E-Q1 this is a 6 channel 2:1 switch, made with qSPI in mind - if you have two them you can create a 12 channel input so that it can support octal SPI - you would just short the control lines on both IC's together so they would act as 1 12 channel device - even though they are two separate IC's.

    We also have the SN3257-Q1,  this is a 4 channel  2:1 switch that is heavily used as a flash memory switch - it can handle Octal SPI if 3 of these IC's are connected to make a 12 channel device out of the 3 4 channel devices.

    These are both Automotive qualified and ready for these types of applications.

    Please let me know if you have any other questions!

    Best,

    Parker Dodson
