Question is if in case of VDD=1.8V USB (CDC device) can work or not? Because in table 12 (10.1 General operating conditions) there is min 3.0V VDD specified for USB operation only!</P></BODY></HTML> Thu, 07 Feb 2019 10:21:52 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC51U68-min-USB-VDD-3V/m-p/879256#M35143 jh0 2019-02-07T10:21:52Z
