The USB OTG support means it can act as either host or device without an external PHY — useful for field updates or direct connection to a sensor hub. The EBI/EMI interface can gluelessly attach parallel NOR Flash, SRAM, or a display controller, which is the typical path for expanding program or frame-buffer memory beyond the internal RAM.
Operating temperature is -20°C to 85°C.
The supply voltage range is 1.71 V to 3.6 V, covering both core and I/O from a single rail.
Yes, the connectivity list includes USB 2.0 OTG, allowing host or device operation without an external PHY.
