In that sense -046 is ok of course.</P> <P>On the other hand the S32G3 supports DDR4LP at up to 3200MT/s speed, both speed grade parts meet this speed. No change in sw setup is required.</P> <P>Regards,</P> <P>Bulat</P> <P>&nbsp;</P> Thu, 27 Jan 2022 17:32:47 GMT https://community.nxp.com/t5/S32G/Slower-LPDDR4/m-p/1406180#M477 Bulat 2022-01-27T17:32:47Z
