i.MX Applications Processors
i.MX50 Family of Applications
Processors
Streamlined Performance
Overview
From the family that introduced the market-leading i.MX508 applications processor for eReaders,
the expanded i.MX50 family is the latest addition to Freescale’s ARM
®
Cortex™-A8 product
portfolio. The i.MX502, i.MX503 and i.MX507 derivatives are targeted toward a variety of portable
applications and offer support for electronic paper display (EPD) in addition to LCD. Along with its
companion Freescale MC34708 power management IC (PMIC), the i.MX50 family delivers a low-
power, streamlined solution for customers seeking ARM Cortex-A8 performance levels with flexible
design features.
Target Applications
• eReaders
• Portable navigation devices
• Outdoor and digital signage
• Patient/client monitoring
• Home and office automation
• DECT phones
Electronic Paper Displays
The i.MX50 family consists of the
first ARM based device with an
integrated EPD hardware interface.
EPDs offer the following
advantages:
• High resolution from any angle
• Sunlight readability
• Mimics the appearance of ink
on paper
• Flexible
• Light weight
• Durable
• Extremely low power
• Replaces paper in many
applications
• Enhanced pixel processing
pipeline (ePxP) to handle post
display frame pre-processing in
hardware with minimal memory
overhead
• OpenVG™ 2-D graphics
acceleration for enhanced User
Interfaces (UIs)
• LP-DDR2 DRAM support for
next-generation, low-power
and high-speed memories, in
addition to mDDR and DDR2
•
•
• Advanced security features
such as high-assurance
boot, DRM support and AES
encryption/decryption

Design Flexibility
The i.MX50 family supports
both LCD and EPD displays to
allow customers the flexibility
in designing their system. The
supported memories include
i.MX
mDDR, DDR2, LP-DDR2, SD/MMC and
raw-NAND with up to 32-bit ECC. Connectivity
features like dual USB with PHY and Fast
Ethernet controller allow customers to connect
to the interfaces they need.

Power Efficiency
The Freescale MC34708 PMIC is optimized for
use with the i.MX50 and helps maximize power
efficiency and battery life while supporting higher
levels of integration to minimize board space
and cost. The MC34708 provides dual phase
switchers for the i.MX50 core and memory, and
USB/UART/audio switching for the mini/micro
USB connector which reduces the connector
count for a more compact design. A switching
charger with dual inputs enables faster charging
from a current limited source, such as USB and
the dual path enables power on even when
the battery has died. The MC34708 supports
the universal charging standard to enable the
selection of the optimal charging profile for the
given charger source.
Freescale PMICs are exclusively designed to
work with our i.MX processor family, providing
optimized feature sets for specific applications.
Freescale’s proven combined solutions are
available as reference designs with full board
support packages (BSPs) and backed by
integrated technical support to offer quality
solutions that get our customers to market faster.
The i.MX50 family also includes power
saving modes and techniques such as state
retention power gating (SRPG) and dynamic
voltage frequency scaling (DVFS) and has five
independent power domains to allow for low
power modes. The i.MX50 solution provides
the performance today’s customers need,
while maintaining low power consumption.
