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
