MCF5407CAI220

The ColdFire V4 MCF540X series Integrated ColdFire V4 Microprocessor. Increasing the internal speed of the core allows higher performance and provides system designers with an easy-to-use lower speed system interface. Based on the concept of variable-length RISC technology, the ColdFire family combines the architectural simplicity of conventional 32-bit RISC with a memory-saving, variable-length instruction set. In defining the ColdFire architecture for embedded processing applications, a 68K-code compatible core combines performance advantages of a RISC architecture with the optimum code density of a streamlined, variable-length M68000 instruction set. The MCF5407 is the first standard product to implement the Version 4 ColdFire microprocessor core. The V4 micro architecture implements a number of advanced techniques, including a Harvard memory architecture, branch cache acceleration logic and limited superscalar support (dual-instruction issue).
