Hi Expert,
Can GPIO1_26/GPIO1_27 be used as I2C0?

Thanks
Daniel

Hello Daniel,
Sorry for my delayed response.
Would you mind telling me more details regarding your setup ?
1. Do you use a custom board or you use a TI AM62x EVM for the development ?
2. How do you intend to use the I2C0 : as a master or as a slave ?
3. What is the maximum desired transfer rate ?
4. Can you provide a schematic (if possible) ?
Kind Regards,
Anastas Yordanov
Hi Sir
I misunderstood the customer's needs.
The customer wants TI to help confirm whether GPIO1_26/GPIO1_27 can be used as a normal GPIO.
Thanks
Daniel
Hi Daniel,
In order to provide more details regarding an accurate GPIO1_26 and GPIO_27 usage on the AM623 I2C0_SDA and I2C0_SCL pins I need more information on the customer use-case:
1. Does the customer intend to also use I2C0 and/or any other of these pins available signals together ( multiplexed in time) with the GPIO1_26 and GPIO1_27 signals ?

2. What peripherals (loads) will be attached to the GPIOs in case they are used as outputs ?
3. It would be nice if customer can provide a schematic (if possible) ?
4. Would you mind updating the title of the thread to reflect the changed topic ?
Kind Regards,

Hi Daniel,
I2C0 is an emulated open drain output type I2C interface.
The Buffer type is LVCMOS.
You should be able to configure as IOs.
In case there is plan to use as I2C, a pullup 4.7K is recommended.
