Processor Expert Software is a development system to create, configure, optimize, migrate, and deliver software components that generate source code for Freescale silicon.

The main features of PEx are:

  • Extensive and comprehensive knowledgebase for all supported silicon encapsulating all pins, registers, etc.
  • Silicon resource conflicts flagged at design time, allowing early correction
  • Simple creation of peripheral drivers without reading silicon documentation
  • Easy integration of an RTOS with peripheral drivers
  • The generated drivers have a cross-platform API that allows easy migration among supported processors.


The user builds an application or library using a wide range of basic building block called Embedded components covering all common tasks (for example, serial communication, timers, ADC, DAC, digital I/O etc.). These components can be configured in graphical user interface and Processor Expert generate a C source code of initialization and runtime control drivers of the processor and its peripherals.


Processor Expert is available:

  • Integrated with CodeWarrior for Microcontrollers
  • As a standalone package called Microcontroller Driver Suite. It supports Kinetis and ColdFire+ microcontrollers. It does not include a compiler or linker and can be used with other non-CodeWarrior IDEs.
  • Integrated with Kinetis Design Stuido (KDS)
