Visit the new CW eTPU Function Selector to create and download your eTPU function set based on new eTPU library functions and CodeWarrior^® compiler.

Visit the eTPU Function Selector to download your eTPU functions from original set1, set2, set3 and set4.

The NXP^® eTPU is a programmable I/O controller with its own core and memory system, allowing it to perform complex timing and I/O management independently of the CPU.

The eTPU is essentially an independent MCU designed for timing control, I/O handling, serial communications, motor and engine control applications
Enhancements include a more powerful processor, which handles high-level C code efficiently and allows for more functionality and increased performance
NXP provides an eTPU functions library that is a superset of the standard TPU library functions; these, along with an available C compiler, make it easy to port older applications to the eTPU
