Hello,
I am designing a circuit that uses the CY7C68013A as a USB peripheral controller.
I have a question below.
1. Does the pull-up voltage of the FX2LP I2C line (SCL and SDA) work at about 2.6V?
- FX2LP reset circuit is directly connected to the pull-up register of FX2LP I2C lines(SCL and SDA) and EEPROM VCC.
- After reset period, voltage of FX2LP's reset line goes to about 2.6V
Regards.

Hi,
Please refer to Page 5 in the FX2LP datasheet: https://www.cypress.com/file/138911/download
The I2C signals should be pulled up to 3.3 V.
