AM62A7-Q1: external pullup for I2C in the WKUP block

KenF

Part Number: AM62A7-Q1

Hello Experts,

My customer is building their own board. They have a question.

Chapter 6.4 of the data sheet states that an external pullup is required for I2C in the WKUP block. Is it needed when they don't use it?

Best regards,
Ken

Hello Ken,

Thank you for the query.

This is Open Drain buffer type I2C interface. Pullups are required irrespective of the IO configuration.

For more information on I2C interface please refer below FAQ.
