Hi NXP,
I was wondering if the SD card slot (J6) on the MCIMX7D-SABRE SDB can support an 802.11ac Wi-Fi module in SDIO3.0 mode.
Two areas of concern:
(1)
Looking at the schematic of the SDB, I noticed the current supply to NVCC_SD1 has max current 100mA.
The other SD2 ports shared the same the current supply (SW2_1V8), which has max current 1,250 mA.
(2)
The max power consumption of my Wi-Fi module is 630 mA. I assume the VDD_SD1 can support it.
My goal is to boot the board from an eMMC (SD3 port) and drive an SDIO Wi-Fi module installed on the SD card slot (J6).
Thank you very much.
Hi Dawei
seems you are right VDD_SD1 can support it, as it is produced from
MEM_3V3, capable of up to 1A, below part of i.MX7 Sabre schematic sch-28590.
NVCC_SD1 supplies only processor SD module and it is sufficient.
Best regards
igor
