The MPC755 and MPC745 Host Processors are high-performance, low-power, 32-bit implementations of the Reduced Instruction Set Computer (RISC) architecture, specially enhanced for embedded applications.
MPC755 and MPC745 processors differ only in that the MPC755 features an enhanced, dedicated L2 cache interface with on-chip L2 tags. The MPC755 is a drop-in replacement for the award winning MPC750 processor and is footprint and user software code compatible with the MPC7400 processor with AltiVec® ™ technology.
The MPC745 is a drop-in replacement for the MPC740 processor and is also footprint and user software code compatible with the MPC603e processor. MPC755/745 processors provide on-chip debug support and are fully JTAG-compliant.
