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.
