Security
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 Security Monitor implements the security
policy, checking algorithm sequencing, and controlling the
Secure State.
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 SLCDC module transfers data from the display memory
buffer to the external display device.
The SSI is a full-duplex, serial port that allows the chip 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 (I
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 i.MX27 processor provides two USB Host controllers and
one USBOTG of which:
Video Codec module supports full duplex video codec with 25
fps VGA image resolution, integrates H.264 BP, MPEG-4 SP
and H.263 P3 video processing standard together.
• USB Host 1 is designed to support transceiverless
• USB Host 2 is designed to support transceiverless
• The USBOTG controller offers HS/FS/LS capabilities in Host
connection to the on-board peripherals in Low Speed and
Full Speed mode, and connection to the ULPI
(UTMI+Low-Pin Court) and Legacy Full Speed transceivers
connection to the Cellular Modem Baseband Processor
mode and HS/FS in device mode. In Host mode, the
controller 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.
