Chapter 1 Overview

1Instruction Set

The MN1030/MN103S Series of 32-bit microcontrollers has a simple instruction set designed to make C

compiler output compact and highly optimized. It minimizes code size by adopting a variable length instruction

format with a basic instruction length of only one byte. It is thus able to minimize increases in assembler

program code size even though the only data transfers supported by the simple instruction set are load and

store.

CPU Cores

AM30, AM31, and AM32 are 32-bit embedded application microcontroller cores from the Matsushita AM

Series of C-oriented 8-, 16-, and 32-bit microcontrollers. Their specifications differ for certain instructions.

The following are brief overviews of these three cores.

MN1030 Series

AM30: First-generation microcontroller core

AM30

supporting connection to ROM, RAM, and Flash memory for instructions and RAM

for data.

AM31: Second-generation microcontroller core

AM31

supporting connection to cache memory for both instructions and data.

General-purpose microcomputer based on this core:

MN103002A

MN103S Series

AM32: Third-generation microcontroller core

AM32

supporting connection to ROM, RAM, Flash memory, and cache memory for

instructions and RAM and cache memory for data.

This document concentrates on the AM32 microcontroller core. When the specifications differ between

cores, separate descriptions appear next to icons indicating the appropriate core or cores.
