Other Parts Discussed in Thread: TPS2051C, SN74AXC8T245, SN74AXC4T774
My customer is designing TUSB1210 with STM32H743IIT6.
The I/O voltage of TUSB1210 is 1.8V,on the other hand, the I/O voltage of STM32H743IIT6 is 3.3V. Thus, we need a level shifter to connect TUSB1210 and STM32H743IIT6.
Could you please tell me the suitable level shifter for this case?
Could you ask ne more question?
If we don't connect USB power switch such as TPS2051C to TUSB1210, What is the proper connection for CPEN pin?
Is it ok that CPEN pin is floating?
Best regards,
Shunsuke Yamamoto
