MCF5249
New Trends Call
for New Technology
While sales of consumer electronics and
home audio devices are growing, and the
popularity of the low-cost, high-capacity
MP3 format is increasing, Freescale
Semiconductor is keeping pace with
innovative devices that address these
trends. The MCF5249 ColdFire^®
microprocessor has entered the market
at a time when a convergence is taking
place between home audio electronics
and computer technologies. At the same
time, Freescale has positioned this
advanced ColdFire device for many other
growing markets such as security and
biometrics for fingerprint recognition
and iris scanning applications. Many
corporations, educational facilities,
law enforcement and public transport
authorities are placing increased
emphasis and investment in the
protection of their staff and assets.
Accordingly, the use of biometric security
is expected to grow exponentially over
the next few years.
Enhanced Features Open the Door
to New Possibilities
Freescale’s ColdFire MCF5249 32-bit
integrated microprocessor, based on the
Version 2 (V2) ColdFire core, includes new
features that are ideal for any application that
requires significant control processing for file
management, signal processing and data
buffering. In fact, the MCF5249, with up to
125 Dhrystone 2.1 MIPS at 140 MHz, is
diverse enough to drive a wide range of
applications, everything from digital audio to
security to industrial control.
The MCF5249 is uniquely designed to
enable fewer system components and,
with low system power requirements,
products with a longer battery life.
Additionally, its integrated features
keep development costs low and time
to market short.
The MCF5249 also protects the investments
you’ve already made in technology and
training. With its seamless, fully compatible
upgrade path, the MCF5249 is an attractive
option for MCF5206e users looking to add
performance and capabilities.
Price Performance That’s Hard to Beat
While the MCF5249 is well suited for the
digital audio market, advanced features make
it a good fit for many industrial control
applications, such as information kiosks,
security and biometrics. The advanced
features include an enhanced
Multiply-Accumulate (eMAC) unit, 96 KB of
on-chip SRAM, 8 KB I-Cache, serial interfaces,
a 12-bit analog-to-digital converter (ADC),
a four-channel direct memory access (DMA),
timers, general-purpose input/output (GPIO)
lines, system integration and a glueless
SDRAM controller.
The MCF5249, our highest performing V2
yet, gives you flexibility to cost-effectively
design the feature-rich products your
customers demand in significantly less time.
New Features Give You
More Design Options
The MCF5249 includes exciting
enhancements—serial audio ports compatible
with industry-standard formats, CD-ROM
block decoder/encoder, SPDIF/EBU
transmitter/receiver, Flash media interface,
IDE master interface—that eliminate the need
for additional audio interfaces. The innovative
on-chip audio bus allows a direct connection
between audio interfaces with no intervention
from the CPU, adding even more intelligence
to this smart device. The ColdFire Family is
designed to accelerate system design time
and reduce development costs.
