The SCC is a hardware component composed of two blocks—the
Secure RAM module, and the Security Monitor. The Secure RAM
provides a way of securely storing sensitive information.
The SDHC controls the MMC (MultiMediaCard), SD (Secure Digital)
memory, and I/O cards by sending commands to cards and
performing data accesses to and from the cards.
The SDMA controller maximizes the system’s performance by
relieving the ARM core of the task of bulk data transfer from memory
to memory or between memory and on-chip peripherals.
The SIM interfaces to an external Subscriber Identification Card. It is
an asynchronous serial interface adapted for Smart Card
communication for e-commerce applications.
The SJC provides debug and test control with maximum security and
provides a flexible architecture for future derivatives or future
multi-cores architecture.
The SSI is a full-duplex, serial port that allows the device to
communicate with a variety of serial devices, such as standard
codecs, Digital Signal Processors (DSPs), microprocessors,
peripherals, and popular industry audio codecs that implement the
inter-IC sound bus standard (I2S) and Intel AC97 standard.
The UART provides serial communication capability with external
devices through an RS-232 cable or through use of external circuitry
that converts infrared signals to electrical signals (for reception) or
transforms electrical signals to signals that drive an infrared LED (for
transmission) to provide low speed IrDA compatibility.
The WDOG module protects against system failures by providing a
method for the system to recover from unexpected events or
programming errors.

supports direct connection of a FS/LS device (without external
hub). In device (bypass) mode, the OTG port functions as gateway
between the Host 1 Port and the OTG transceiver.
