The MCF5253 is a general purpose system controller

with over 125 Dhrystone 2.1 MIPS @ 140 MHz

performance. The integrated peripherals and EMAC

allow the MCF5253 to replace both the microcontroller

and the DSP in certain applications. Most peripheral pins

can also be remapped as general purpose I/O pins.
