Overview

Pressing its leadership in 32-bit processing

into new territory, Freescale Semiconductor

introduces a single-chip solution to address

the need for a cost-sensitive, low-power,

32-bit microcontroller that fills the gap

between existing 16-bit and 32-bit products.

Applications requiring traditional general

purpose microcontroller functionality have

rising computational performance and memory

requirements. The challenge is to provide a

microcontroller that offers it all—low-power

operation in small footprint configurations with

options for computational-intensive tasks.

There is also a requirement for a roadmap

with seamless migration that includes

robust full-featured embedded controllers.

Freescale’s MCF521x embedded controller

family encompasses all this and more.

It features power management options and

low-power modes along with right-sized

feature sets offering a host of peripherals

commonly used in microcontroller applications.

Trends

As a competitive advantage in the embedded

marketplace becomes harder to secure,

protecting a company’s intellectual property (IP)

becomes more critical. The robust and secure

flash technology offered by the MCF521x family

of embedded controllers gives designers a

tool for protecting intellectual property. For

applications requiring code security, the

MCF521x family of embedded controllers offers

a single-chip solution with up to 256 KB of high

performance, near-single access, interleaved

and securable embedded Flash memory.

Moreover, the MCF521x embedded controller

communication peripherals provide easy

connection to other systems. Three universal

asynchronous receiver/transmitters (UARTs)

enable medium to long-distance communication

to other control systems or computers.

An inter-integrated circuit (I

2

C) and

queued serial peripheral interface (QSPI)

enable in-system communication to

connected peripherals and systems,

including LCDs and keyboards. All this

is offered along with the high performance

V2 ColdFire core that even incorporates a

multiply and accumulate module (MAC)

for DSP-like operation.

Building on years of experience in

industrial control and communications,

the MCF521x embedded controller family

adds to a portfolio that today includes

32-bit embedded controllers with Flash

memory and on-chip Ethernet and CAN

networking interfaces as well as 16-bit

microcontrollers that offer optimized

system solutions with Ethernet and

Physical interfaces for complete

networking solutions. The MCF521x

family of embedded controllers offers

designers a powerful, cost-effective

solution with a variety of supporting

software and development tools that ease

the transition into 32-bit technology.

Tools and Support

The ColdFire embedded controller family

benefits from extensive support by

world-class development tools suites

offered through leading third-party tools

developers. The MCF5213EVB

development system includes, at no extra

cost, CodeWarrior Special Edition

software in each kit and professional tools

and systems from such partners as Green

Hills, Wind River Systems, Accelerated

Technology, ARC and others. The open

source software and graphical initialization

tools used in the MCF5213EVB system

make no-cost development easy

to get and easy to use.
