I2C(3)
I2C module
Connectivity
peripherals
Inter-IC Communication (I2C) is an industry-standard, bidirectional serial bus
that provides a simple, efficient method of data exchange, minimizing the
interconnection between devices. I2C is suitable for applications requiring
occasional communications over a short distance between many devices.
The interface operates up to 100 kbps with maximum bus loading and timing.
The I2C system is a true multiple-master bus, including arbitration and
collision detection that prevents data corruption if multiple devices attempt to
control the bus simultaneously. This feature supports complex applications
with multiprocessor control and can be used for rapid testing and alignment
of end products through external connections to an assembly-line computer.
IIM
IC
Identification
Module
Security
The IIM provides the primary user-visible mechanism for interfacing with
on-chip fuse elements. Among the uses for the fuses are unique chip
identifiers, mask revision numbers, cryptographic keys, and various control
signals requiring a fixed value.
IOMUX
I/O multiplexer Pins
Each I/O multiplexer provides a flexible, scalable multiplexing solution:
Up to eight output sources multiplexed per pin
Up to four destinations for each input pin
Unselected input paths are held at constant level for reduced power
consumption
KPP
Keypad port
Connectivity
peripherals
KPP can be used for either keypad matrix scanning or general purpose I/O.
LCDC
LCD
Controller
Multimedia
peripherals
LCDC provides display data for external gray-scale or color LCD panels.
LCDC is capable of supporting black-and-white, gray-scale, passive-matrix
color (passive color or CSTN), and active-matrix color (active color or TFT)
LCD panels.
MAX
ARM platform
multilayer
AHB crossbar
switch
ARM platform
MAX concurrently supports up to five simultaneous connections between
master ports and slave ports. MAX allows for concurrent transactions to
occur from any master port to any slave port.
PWM(4)
Pulse width
modulation
Connectivity
peripherals
The Pulse-Width Modulator (PWM) has a 16-bit counter and is optimized to
generate sound from stored sample audio images. It can also generate
tones. The PWM uses 16-bit resolution and a 4x16 data FIFO to generate
sound.
SDMA
Smart DMA
engine
System control
The SDMA provides DMA capabilities inside the processor. It is a shared
module that implements 32 DMA channels.
SIM(2)
Subscriber
identity
module
interface
Connectivity
peripherals
The SIMv2 is an asynchronous interface with additional features for allowing
communication with smart cards conforming to the ISO/IEC 7816
specification. The SIM is designed to facilitate communication to SIM cards
or pre-paid phone cards.
SJC
Secure JTAG
interface
System control
peripherals
The System JTAG Controller (SJC) provides debug and test control with
maximum security.
SLCD
Smart LCD
controller
Multimedia
peripherals
The SLCDC module transfers data from the display memory buffer to the
external display device.
SPBA
Shared
peripheral bus
arbiter
System control
The SPBA controls access to the shared peripherals. It supports shared
peripheral ownership and access rights to an owned peripheral.
