3.5.11.3.3 MMC2 - M2 Key E Interface

The AM62x-Low Power SK EVM has an M.2 Key E interface for connecting WiFi BT modules connected to MMC2, UART2 instances and McASP1 interface through buffers. The M.2 Module is connected to 4-bit IO of the MMC2 interface.The Module requires one power supply, 3.3V. Power to M.2 module is supplied from on board Power supply rails.

The MMC2 interface of the SoC is powered by the VDDSHV6 power domain, which is connected to 1.8V IO supply.
