NVCC_LCD I/O supply

[mrudangshelat]

Hi, I am using iMX6D/Q for my new product. Since my product is battery operated and low power design, I have used all NVCC_xxx supply on 1.8V except NVCC_LCD. I am using this NVCC_LCD I/O as GPIO with 3.3V rail, not as LCD data. Can i use NVCC_LCD bank Muxing as a GPIO on 3.3V? Will it create any issue on my design? I am using only 5 GPIOs from this bank rest of the IOs are NC. Please provide your valuable feedback. Regards, Mrudang

Hi Mrudang

there will no issues with supplying NVCC_LCD at 3.3V rail and

others on 1.8V, as power domains are independent from each other.

Best regards

igor
