32-bit Fact Sheet
Target Applications
• HVAC building and control systems
• Health care monitoring
• Fire/security control and
• Factory and automation systems
• Measurement equipment
• Hand-held medical/industrial applications
• Low-power industrial applications
Overview
The Flexis
point on the Freescale Controller Continuum,
where 8- and 32-bit compatibility becomes
reality. The Flexis series includes complementary
families of 8-bit S08 and 32-bit ColdFire
microcontrollers that share a common set of
peripherals and development tools to deliver the
ultimate in migration flexibility.
The QE family, comprised of a pin-compatible
8-bit and 32-bit device duo, is the first family in
the Flexis series.
The 32-bit MCF51QE128 device extends the low
end of the ColdFire embedded controller family
with up to 128 KB flash memory and a 12-bit
analog to digital converter (ADC) with up to 24
channels. The MCF51QE128 includes up to 3.6V
supply voltage, a 50 MHz CPU core and three
timers for improved motor control—perfect for
medical devices such as health care monitoring
instrumentation and industrial equipment
including networked smoke detectors and
security cameras.
The 32-bit MCF51QE128 is pin-, peripheral- and
tool-compatible with the 8-bit S08QE128 device,
providing unprecedented design freedom across
the performance spectrum.
