The Industry is Changing
► Embedded
developers increasingly tasked to
design for a portfolio of products ranging in
performance
► 8-bit
users driven to reach performance ceiling with
increased demands for performance and
functionality
► Economies
of scale and process technology
improvements push costs down
on 32-bit MCUs making them more affordable
► Migrating
across continuum of performance and
price options isn’t easy or quick when different bit
architectures require re-coding and different tools
Freescale is breaking bit boundaries to provide a simple and seamless path
to performance between 8-bit and 32-bit MCUs

What is QE128?
Flexis™ QE128 low power devices are the industry’s first 8- and
32-bit pin, peripheral and tool compatible MCUs which make the
design process quick, easy and limitless.
Unprecedented
compatibility
Ultra-low power
Easy to use
Freescale’s Controller
Continuum provides unique
flexibility to transition from 8bit to 32-bit. With pin,
peripheral and tool
compatibility, the Flexis QE
devices simplify and speed
the design process.
Through an optimized
architecture that provides
lower operating voltage and
current, the QE128 devices
offer industry-leading ultralow power benefits to
extend battery life.
Common CodeWarrior
development tools, training
and documentation gets
you on the design fast
track. Pin and peripheral
compatibility avoids
learning new codes and
tools.
