Audience
This manual is intended for system software and hardware developers and applications programmers who
want to develop products with the PXD20 device. It is assumed that the reader understands operating
systems, microprocessor system design, basic principles of software and hardware, and basic details of the
Power Architecture.
Organization
This document includes chapters that describe:
• The microcontroller as a whole
• The functionality of the individual modules on the microcontroller
When the microcontroller is specified as “PXD20,” the reader is instructed to apply this information to all
of the microcontrollers specified on the front cover of this manual, unless individual device-specific details
are provided in that chapter.
The following summary provides a brief description of the major sections of this manual:
• Chapter 1, Introduction, includes general descriptions of the modules and features incorporated in
the device while focusing on new features.
• Chapter 2, Memory Map, provides a high-level listing of the PXD20 memory map.
• Chapter 3, Signal Description, summarizes the external signal functions, their static electrical
characteristics, and pad configuration settings for the PXD20.
• Chapter 4, Safety, describes a set of features to support using the PXD20 for applications that need
to fulfill functional safety requirements.
• Chapter 5, Analog-to-Digital Converter (ADC), describes the ADC module implemented on the
PXD20.
