2 / 56 page  SCF5250 Data Sheet: Technical Data, Rev. 1.3 2 Freescale Semiconductor integrated peripherals and enhanced MAC unit allow the 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. 1.1 Orderable Part Numbers Table 1 lists the orderable part numbers for the SCF5250 processor. 1.2 SCF5250 Features This section provides brief descriptions of the features of the SCF5250 processor. 1.2.1 ColdFire V2 Core 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). Table 1.
