classic Power Architecture instruction set, contain
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
