3.9SD Interface
MODULE provides a 4-bit SD/MMC/eMMC interface with clock rate up to 200 MHz.
When connected to a SD or MMC card, the voltage of SD interface is 1.8/2.85V, which is compatible with
Secure Digital Physical Layer Specification version 3.0 and SDIO Card Specification version 3.0.It supports
up to 128GB SD cards.
When connected to a eMMC card, the interface voltage will be a sigle 1.8V, which is compatible with eMMC
Specification, version 4.5. It supports up to 128GB eMMC cards.
