Introduction
SCF5250 to replace both the microcontroller and the DSP in certain applications. Most peripheral pins can
also be remapped as General Purpose I/O pins.

The ColdFire processor Version 2 core consists of two independent, decoupled pipeline structures to
maximize performance while minimizing core size.The instruction fetch pipeline (IFP) is a two-stage
pipeline for prefetching instructions. The prefetched instruction stream is then gated into the two-stage
operand execution pipeline (OEP), which decodes the instruction, fetches the required operands, and then
executes the required function. Because the IFP and OEP pipelines are decoupled by an instruction buffer
that serves as a FIFO queue, the IFP can prefetch instructions in advance of their actual use by the OEP,
which minimizes time stalled waiting for instructions. The OEP is implemented in a two-stage pipeline
featuring a traditional RISC data path with a dual-read-ported register file feeding an arithmetic/logic unit
(ALU).
1.2.2
The SCF5250 provides four fully programmable DMA channels for quick data transfer. Single and dual
address mode is supported with the ability to program bursting and cycle stealing. Data transfer is
selectable as 8, 16, 32, or 128-bits. Packing and unpacking is supported.
Two internal audio channels and the dual UART can be used with the DMA channels. All channels can
perform memory to memory transfers. The DMA controller has a user-selectable, 24- or 16-bit counter and
a programmable DMA exception handler.
External requests are not supported.
