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 06:41:36 GMT https://community.nxp.com/t5/Wireless-MCU/MC33814/m-p/676854#M3069 berniecheah 2017-07-20T06:41:36Z Re: MC33814 https://community.nxp.com/t5/Wireless-MCU/MC33814/m-p/676855#M3070 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P><SPAN>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.
