Embedded Controllers

Fact Sheet

The Market Challenge

The need for connectivity and system

communication continues to be a steadily

growing trend. However, the challenge

most designers face is how to accommodate

the different methods of connectivity within

a system. There is a need to select a

processor with the right level of integration

and performance enhancement features to

accommodate system-to-system, in-system

and secure networked communication. There

is also a need for a roadmap with seamless

migration that includes an entire portfolio of

full-featured embedded processors with an

emphasis on connectivity. By introducing the

integrated USB host and integrated USB

On-The-Go (USB-OTG) modules to the

68K/ColdFire portfolio, the MCF537x family

of microprocessors offers a single chip

solution to address the growing need for

flexible communication within industrial

control systems.

Connectivity

To address the growing need for

system-to-system communications, the MCF537x

introduces the integrated USB host and integrated

USB-OTG module to the 68K/ColdFire portfolio

of features. These on-chip USB modules address

the need for system flexibility and enables support

for a rapidly growing number of applications where

direct communication is required between USB

devices such as printers, mass storage devices

and input devices. The MCF537x also includes

three on-chip universal asynchronous

receiver/transmitters (UARTs), common on a

majority of 68K/ColdFire devices, for direct

communication between computers, terminals and

other devices. Both the I

C and queued serial

peripheral interface (QSPI) peripherals are ideal

for supporting in-system communication to

connected peripherals. The MCF537x family

further accommodates flexibility in communication

by supporting networked communication via the

integrated 10/100 Ethernet controller. This

Integrated Fast Ethernet Controller (FEC) in

conjunction with the on-chip hardware encryption

module ensures secure connectivity with no

compromise to system performance.

Flexibility and Performance

The MCF537x offers many peripherals that

give designers the flexibility they need to

accommodate the multiple functions in their

systems. The MCF537x features an integrated

USB-O

TG module that allows a system to serve

as either the master or a device in a given

application. The MCF537x also features an

integrated SDRAM controller that supports either

DDR or SDR memory for designers who wish to

modify their designs to accommodate one or the

other. Other advanced features include an

enhanced multiply-accumulate (eMAC) unit, which

handles DSP-like instructions. The MCF537x

family of devices also builds upon the competitive

high-performance legacy of the 68K/ColdFire

family, offering up to 211 (Dhrystone 2.1) MIPS

at 240 MHz of performance, making them

one of the highest performing microprocessors

in its class.

Security

As the need for networked connectivity increases

in embedded applications, a higher level of data

protection is required. The MCF537x family offers

an optional on-chip Hardware Encryption Module

to address this need. The integrated hardware

encryption module is designed to support a variety

of encryption algorithms and protocols while

maintaining overall system performance.

68K/ColdFire Hardware and Software

Tools Support

The ColdFire

embedded processor family benefits

from world-class support by several leading

third-party developers. These developers support a

wide variety of 68K/ColdFire devices, making it

possible to use the same tool set across several

devices in the ColdFire portfolio. In addition to

maintaining this similar tool support across the

entire ColdFire family, the MCF537x offers

peripherals that are similar across several ColdFire

devices, further enabling smooth migration within

the ColdFire device portfolio. The Freescale

M5373EVB evaluation and development system

includes, at no extra cost*, CodeWarrior

Special

Edition software. Professional tool support is also

available to ColdFire third-party tool vendors.

Open source software is available for the MCF537x

family of microcontrollers.
