We are using a 5V buffer at the moment because we do not want to risk it.</SPAN></P></BODY></HTML> Thu, 20 Jul 2017 06:43:24 GMT https://community.nxp.com/t5/Wireless-MCU/MC33814/m-p/676879#M3071 berniecheah 2017-07-20T06:43:24Z Re: MC33814 https://community.nxp.com/t5/Wireless-MCU/MC33814/m-p/676880#M3072 <HTML><HEAD></HEAD><BODY><P><SPAN style="font-size: 11.0pt;">I’m afraid that it is not possible to connect the inputs on the MC33814 can be connected directly to the outputs from a 3.3v MCU without using a level shifter, the reason is that the Digital interface input of the MC33814 is dependent from VCC voltage and VCC voltage should be 5V.
