32-bit ColdFire® MCU offers cost-effective connectivity
As well as cost-saving functionality,
the MCF5225x range integrates
connectivity options supporting the
main industrial protocols. These include
a 10/100BaseT Ethernet controller and
a USB On-the-Go controller, with an
optional FlexCAN controller.
To support stringent industrial requirements,
the MCF5225x integrates numerous features
such as an independently-clocked real-time
clock, a low-voltage detector module and a
second watchdog controller with
independent clock source.
For secure communications there is an
optional hardware cryptography accelerator
and random number generator.
To help reduce overall design costs,
Freescale is bundling the MCF5225x with the
MQX Real-Time Operating System (RTOS) free
of charge. In addition, Freescale and their
3rd-party developers will make available a
range of reference designs and examples.
Due to the layout of the pins in the LQFP
packages, designers can also implement
Ethernet using a low-cost 2-layer PCB
solution. The 2-layer Ethernet-enabled PCB
can save substantial bill-of-materials cost
compared to the more complex 4- or 6-layer
solutions that are normally required.
As well as enhanced connectivity, these
MCUs feature a wide range of integrated
control functionality, a selection of timers, a
dedicated PWM
timer and a variety
of serial
communications
controllers to
connect to onboard
functions
and to external
modules and
peripherals. The
MCF5225x has up
to 512kbyte Flash
memory, 64K SRAM
and an external
bus interface to
connect to external
memories and
peripherals up to a
maximum width of
16 bits.
