i.MX233 Applications Processor
32-bit Embedded Microprocessor – ARM^®
Overview
The i.MX233 applications processor extends
Freescale’s ARM9 portfolio and introduces
several unique features such as power
management, analog audio, 12-bit ADC’s and
a touch screen controller that allows customers
to eliminate external components, reducing
their overall system bill of materials cost. The
i.MX233 integrates industry-leading power
management technology to manage the power
sequencing required by the processor itself
and supplies power to other components in
the system, such as external memories, from
a single Li-Ion battery. Additionally, analog
audio features such as the stereo ADC/DAC
and amplifiers, plus a mono speaker amplifier
provide a complete solution in a single device
for multimedia applications. Furthermore, many
consumer applications require a rich graphical
user interface which is supported with the LCD
touch screen controller and basic hardware
graphics acceleration with the pixel pipeline
processor.

Key Features
CPU
• ARM926EJ-S™ runs up to 454MHz
• 16KB I & D L1 Cache
Power Management
• Integrated DC-DC converter with multiple
channel outputs
• Supports Li-Ion batteries
• Direct power from 5V source (USB, wall
power or other source)
• Battery charging capability
• On-chip silicon speed and temp sensors
The i.MX233 is offered in two packages to
provide more tailored options for the various
target applications. The 169 BGA package
provides access to all of the features of the
i.MX233. The 128 LQFP package provides
a subset of these features in order to fit into
the smaller pin count package. This smaller
package option is ideal for cost-sensitive entry
level applications that use small displays, don't
require touchscreen user interface and have
manufacturing restrictions (number of board
layers). The feature differences are shown in the
block diagram and table.

Benefits
CPU Performance and Low Power
454MHz ARM9 CPU with ample headroom
for many consumer and embedded
applications without sacrificing battery life.
For plugged in “always on” devices, the low
power consumption of the i.MX233
can improve energy efficiency.
Simplified Development
The integration of mixed-signal analog such
as power management, analog audio and
A/D channels reduces system complexity
and speeds time-to-market. In addition, an
image processing unit supporting 24-bit VGA
displays is integrated to provide rich user
interfaces.With a wide range of connectivity
options, such as UART, SDIO, USB and I²C,
the i.MX233 processor provides the ability to
connect wirelessly to other devices, through
the use of off-chip Bluetooth^™, Wi-Fi and other
wireless protocols.
