Overview

The Flexis series of controllers is the connection

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 V1

microcontrollers that share a common set ofperipherals 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 controlperfect 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.
