2 Functional Description and Application Information
The i.MX35 consists of the following major subsystems:
• ARM1136 Platform—AP domain
• SDMA Platform and EMI—Shared domain
2.1 Application Processor Domain Overview
The applications processor (AP) and its domain are responsible for running the operating system and
applications software, providing the user interface, and supplying access to integrated and external
peripherals. The AP domain is built around an ARM1136JF-S core with 16-Kbyte instruction and data L1
caches, an MMU, a 128-Kbyte L2 cache, a multiported crossbar switch, and advanced debug and trace
interfaces.

Brief Description
I2C(3) I2C module ARM
ARM1136
platform
peripherals
Inter-integrated circuit (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 among many devices. The interface operates at up to
100 kbps with maximum bus loading and timing. The I2C system is
a true multiple-master bus, with arbitration and collision detection
that prevent 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.

Security
modules
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

ARM
signals and pin
multiplexing
Pins
Each I/O multiplexer provides a flexible, scalable multiplexing
solution with the following features:
• Up to eight output sources multiplexed per pin
• Up to four destinations for each input pin
• Unselected input paths held at constant levels for reduced power
consumption

Multimedia
peripherals
The IPU supports video and graphics processing functions. It also
provides the interface for image sensors and displays. The IPU
performs the following main functions:
• Preprocessing of data from the sensor or from the external
system memory
• Postprocessing of data from the external system memory
• Post-filtering of data from the system memory with support of the
MPEG-4 (both deblocking and deringing) and H.264 post-filtering
algorithms
• Displaying video and graphics on a synchronous (dumb or
memory-less) display
• Displaying video and graphics on an asynchronous (smart)
display
• Transferring data between IPU sub-modules and to/from the
system memory with flexible pixel reformatting
KPP Keypin port ARM
Connectivity Can be used for either keypin matrix scanning or general purpose
peripherals I/O.

The OSCAUDIO oscillator provides a stable frequency reference for
the PLLs. This oscillator is designed to work in conjunction with an
external 24.576-MHz crystal.
