Introduction

1.1

Document overview

This document provides electrical specifications, pin assignments, and package diagrams

for the SPC5x series of microcontroller units (MCUs). For functional characteristics, see the

SPC5x microcontroller reference manual.

1.2

Description

The SPC58xNx microcontroller belongs to a family of devices superseding the SPC5x

family. SPC58xNx is built on the legacy of the SPC5x family, while introducing new features

coupled with higher throughput to provide substantial reduction of cost per feature and

significant power and performance improvement (MIPS per mW).
