Fact Sheet
Overview
Freescale Semiconductor continues to
expand the broad portfolio of ColdFire
embedded controllers with the low cost,
low power MCF5221x product family.
The MCF5221x represents a family of
highly-integrated 32-bit microcontrollers
based on the popular Version 2 ColdFire
core with a multiply-accumulate unit (MAC)
and divider providing 76 Dhrystone 2.1 MIPS
at a frequency up to 80 MHz out of flash
memory. An integrated USB On-The-
Go (OTG) controller makes it ideal for
applications requiring device or host
connectivity functionality.
The MCF5221x gives product designers
a cost-effective, full-featured solution
that allows them to create next-generation
systems quickly and efficiently. In addition
to the USB-OTG, the MCF5221x features
16 Kbytes of internal static random access
memory (SRAM) and up to 128 Kbytes
of flash memory, 8-channel, 12-bit
analog-to-digital converter (ADC), four
32-bit timers with DMA request capability
and a 4-channel DMA controller.
The communications peripherals enable
easy connection to other systems. Three
universal asynchronous receiver/transmitters
(UARTs) provide medium to long distance
communication to other control systems
or computers. Two inter-integrated
circuit (I
peripheral interface (QSPI) allow in-system
communication to connected peripherals.
The MCF5221x family is ideal for embedded
control applications needing USB connectivity
such as general industrial control, factory
and home automation, electronic point-of-sale
terminals, medical devices, electronic test
equipment and consumer applications.
