https://community.nxp.com/t5/Power-Management/NVT4858-SDIO-voltage-translation-for-STM32F413/m-p/1753638#M3088 <P>Hi,&nbsp;</P><P><SPAN>On our PCB we are designing a microcontroller STM32F413 at 1.8V and are looking for a suitable level translator to 3.3V for the on-board microSD connector (diagram below). The microcontroller only supports up to SDIO v2.0 so we are not expecting to run SDIO in any UHS mode on this board. Would NVT4858 be suitable for our application?&nbsp;&nbsp;&nbsp;</SPAN></P><P><SPAN>I also noticed NVT4858 has an optional clock feedback output. I guess it is not required for SD cards in non-UHS modes?</SPAN></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Thai1_0-1699376805977.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/248841i9472B9B311887B81/image-size/medium?v=v2&amp;px=400" role="button" title="Thai1_0-1699376805977.png" alt="Thai1_0-1699376805977.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Thai1_1-1699377142689.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/248843i722A10A431B35A1A/image-size/medium?v=v2&amp;px=400" role="button" title="Thai1_1-1699377142689.png" alt="Thai1_1-1699377142689.png" /></span></P> Wed, 08 Nov 2023 10:49:27 GMT Thai1 2023-11-08T10:49:27Z https://community.nxp.com/t5/Power-Management/NVT4858-SDIO-voltage-translation-for-STM32F413/m-p/1753638#M3088 <P>Hi,&nbsp;</P><P><SPAN>On our PCB we are designing a microcontroller STM32F413 at 1.8V and are looking for a suitable level translator to 3.3V for the on-board microSD connector (diagram below).
