system. In order to minimize software overhead and improve operational reliability, all major systems such

as CPU core, DMA controller, interrupt controller, crossbar bus system, memory systems, peripheral

systems, and memory protection unit, include built in redundancy and or robust system monitoring. Lock

Step Redundancy Checking Units are implemented at each output of this Sphere of Replication (SoR).

ECC is available for on-chip RAM and flash memories. A programmable fault collection and control unit

monitors the integrity status of the device and provides flexible safe state control.

The host processor core of the PXS20 is the latest CPU from the e200 family of compatible Power

allowing high performance with minimum power consumption.

The peripheral set provides high-end electrical motor control capability with very low CPU intervention,

thanks to the on-chip Cross Triggering Unit (CTU).

This device incorporates high-performance 90 nm embedded flash-memory technology to provide sub-

stantial cost reduction per feature and significant performance improvement.
