The PXS20 series microcontrollers are system-on-chip

technology, are 100% user-mode compatible with the

enhancements that improve the architecture’s fit in

embedded applications, include additional instruction

support for digital signal processing (DSP), and integrate

technologies to support highly reliable and safe

operation across a range of industrial, medical and

transportation safety critical applications. These

microcontrollers include a rich set of peripherals for

complex real time control, such as an enhanced timer

unit, analog-to-digital converters, and multiple serial

communications modules.

The PXS20 is designed for applications requiring a high

Safety Integrity Level (SIL).

All devices in this family are built around a dual core

safety platform with an innovative safety concept that

reduces system cost and effort for the customer to

achieve IEC61511 or IEC61508 certification of their
