Introduction

1.1

Document overview

This document describes the features of the family and options available within the family members, and highlights important

electrical and physical characteristics of the devices.

This document provides electrical specifications, pin assignments, and package diagrams for the PXS20 series of

microcontroller units (MCUs). For functional characteristics, see the PXS20 Microcontroller Reference Manual. For use of the

PXS20 in a fail-safe system according to safety standard IEC 61508, see the Safety Application Guide for MPC5643L.

The PXS20 MCU series is available in two silicon versions, or “cuts”. These are referred to as “cut1” and “cut2” throughout

this document. Functional differences between the two cuts are clearly identified with the labels “cut1” and “cut2”.

1.2

Description

The PXS20 series microcontrollers are system-on-chip devices that are built on Power Architecture technology and contain

enhancements that improve the architecture’s fit in embedded applications, include additional instruction support for digital

signal processing (DSP) and integrate technologies such as an enhanced time processor unit, enhanced queued analog-to-digital

converter, Controller Area Network, and an enhanced modular input-output system.

The PXS20 family of 32-bit microcontrollers is the latest achievement in integrated safety controllers. The advanced and

cost-efficient host processor core of the PXS20 family complies with the Power Architecture embedded category. It operates at

speeds as high as 120 MHz and offers high-performance processing optimized for low power consumption. It capitalizes on the

available development infrastructure of current Power Architecture devices and is supported with software drivers, operating

systems and configuration code to assist with users’ implementations.
