Tool/software:
Hello TI Support Team.
We are looking for a fast switch (1x2) for switching the CPU/SD bus.
The switch should be able to switch the CPU/SD bus between an SD-Card and an eMMC flash.
The SD bus switch should also be suitable for high-speed (HS200 and HS-DDR) data transfer.
Can we use the TMUC646 as a switch between an SD-Card and an eMMC flash?
Can you recommend another component that is suitable for this application?
Ideally, the bus switch should also have a voltage conversion.
Note:
- The CPU/SD bus operates with a 1.8V logic level.
- The SD card operates with a 3.3V logic level.
- The eMMC flash operates with a 3.3V logic level.
Thank you very much.
Kind regards.
