WiLink8 with TWL1200

Other Parts Discussed in Thread: WL1837, TWL1200

Good day

My design involves a combination of the WiLink 8 solution combined with the TWL1200 level translator. The question is regarding the WL1837 SDIO lines PUs requirement. Does the TWL1200s' PUs enough for the WL1837 SDIO lines, or do I need to place additional 10K PU on those lines (or at least place holders)?

Thanks

Thank you for your answer. I am also looking for the option to eliminate the need of the external 32K osc, and to level shift the SoCs' 3.3V GPIO 32K output. This information is missing from the provided article.

Thanks
