2. Architecture
ALFAT SoC processor is an ARM Cortex-M3 processor that runs a robust file system
engine with SD and USB host (mass storage) drivers. The processor access storage
media though its 4-bit SD interface and two USB host 2.0 interface. One of the USB host
ports is capable running at high speed 480mbps with external ULPI HS PHY chip.
ALFAT SoC processor provides 3 different standard access interfaces for the host system,
UART, SPI or I2C.
