Embedded Controllers

The embedded market is growing at an

unprecedented rate, with the average

consumer coming into contact with 350

semiconductors a day. The proliferation

of electronics in our daily lives brings

added challenges to the designer in finding

the optimum solution for their system.

By delivering on the development roadmap

for the ColdFire

®

Family, Freescale

Semiconductor provides room to grow and

powerful new capabilities for designers

who are eager to create advanced

electronic products while leveraging

previous technology investments.

A High-Performance,

Cost-Effective Solution

Freescale’s ColdFire MCF5206e 32-bit

integrated microprocessor, an enhanced

version of the popular MCF5206, combines

a Version 2 (V2) ColdFire core with

peripheral functions such as a DRAM

controller, timers, parallel and serial

interfaces and system integration.

Designed for embedded control applications,

such as electronic point-of-sale (EPOS)

terminals, vacuum system controllers, I/O

controllers for gaming machines, local area

network (LAN) interfaces, I/O cards or

closed-circuit television (CCTV) cameras,

the MCF5206e is a cost-effective,

high-performance 54 MHz solution that

is engineered to help designers get to

market fast. These features on the

MCF5206e provide ease of use through

integration on a single chip, reducing

overall design time. Enhancements from

the MCF5206 version include 4 KB I-Cache

and 8 KB SRAM, increased frequency

, a

multiplier-accumulator (MAC) unit, hardware

divide and a two-channel DMA controller.

What’s the bottom line? The MCF5206e is

engineered to deliver enhanced system

performance without impacting the low overall

system costs or rapid development times

you’ve come to expect from the

ColdFire Family.

Impressive System Performance

The additional MAC module and hardware

divide help to significantly increase

performance of complex arithmetic functions

common to DSP applications. On-chip

instruction cache and SRAM with one-cycle

access to critical code and data help further

accelerate program performance.

For 68K users, the MCF5206e offers more

than six times the performance of the

MC68340 with a similar peripheral set and

up to 15 times the performance of the

MC68306. The MCF5206e’s package,

pinout and integration mix also create a fully

compatible upgrade path for current

MCF5206 designs and result in an almost

threefold improvement in performance.
