Timer
The RTC module provides a current stamp of seconds,
minutes, hours, and days. Alarm and timer functions are also
available for programming. The RTC supports dates from the
year 1980 to 2050.
The RTIC ensures the integrity of the contents of the peripheral
memory and assists with boot authentication.

SAHARA2
SAHARA2 is a security co-processor which forms part of the
Platform Independent Security Architecture (PISA), and can be
used on cell phone baseband processors or wireless PDAs.

SAHARA2
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.
