This document provides an overview of the MPC565/MPC566 microcontrollers, including a

block diagram showing the major modular components, sections that list the major features,

and differences between the MPC565/MPC566 and the MPC555. The MPC565 and MPC566

devices are members of the Motorola MPC500 RISC Microcontroller family. The parts herein

will be referred to only as MPC565 unless specific parts need to be referenced.

Introduction

The MPC565 device offers the following features:

•

Unified system integration unit (USIU), a flexible memory controller, and improved

interrupt controller

•

1 Mbyte of Flash memory (UC3F)

— Typical endurance of 100,000 write/erase cycles @ 25ºC

— Typical data retention of 100 years @ 25ºC

•

36 Kbytes of static RAM (two CALRAM modules)

— 8 Kbytes of normal access or overlay access (sixteen 512-byte regions)

— 4 Kbytes in CALRAM A, 4 Kbytes in CALRAM B

•

Three time processor units (TPU3)

— TPU3 A and TPU3 B are connected to DPTRAM AB (6 Kbytes)

— TPU3 C is connected to DPTRAM C (4 Kbytes)

•

A 22-timer channel modular I/O system (MIOS14)

— Same as MIOS1 plus a real-time clock sub-module (MRTCSM), 4 counter

sub-modules (MCSM), and 4 PWM sub-modules (MPWMSM)

•

Three TouCAN modules (TouCAN_A, TouCAN_B, and TouCAN_C)

•

Two enhanced queued analog to digital converters (QADC64E A, QADC64E B)

with analog multiplexers (AMUX) for 40 total analog channels. These modules are

configured so each module can access all 40 of the analog inputs to the part.
