I was wondering if there was any documentation regarding using the I2C pins on the mc33771 to communicate to another device? I do not require the eeprom chip on the evaluation board. I'd like to expose those pins so I could attach some sensors.</SPAN></P></BODY></HTML> Fri, 24 Jan 2020 20:04:13 GMT https://community.nxp.com/t5/Power-Management/mc33771-i2c/m-p/1002338#M736 jesus_hernandez 2020-01-24T20:04:13Z Re: mc33771 i2c https://community.nxp.com/t5/Power-Management/mc33771-i2c/m-p/1002339#M737 <HTML><HEAD></HEAD><BODY><P>Hello Jesus,</P><P></P><P>The I2C interface on the MC33771 is intended to be used only with an&nbsp;external EEPROM&nbsp;to store calibration parameters defined by the user.
