The Motorola MPC603r microprocessor is a low-power implementation of the PowerPC Reduced Instruction
Set Computer (RISC) architecture. The MPC603r microprocessor offers workstation-level performance packed
into a low-power, low-cost design ideal for desktop computers, notebooks and battery-powered systems,
as well as printer and imaging equipment, telecommunications systems, networking and communications infra-
structure, industrial controls, and home entertainment and educational devices. Industrial-grade, extended
temperature MPC603r microprocessors are available for harsh operating environments. The MPC603r micro-
processor is software- and bus-compatible with the MPC7xx and MPC74xx microprocessor families.
S uperscalar M icroprocessor
The MPC603r microprocessor is a superscalar design
capable of issuing three instructions per clock cycle into five
independent execution units, including:
Integer unit
Load/Store unit
Floating-point unit
System register unit
Branch processing unit

The ability to execute multiple instructions in parallel, to pipeline
instructions, and the use of simple instructions with rapid
execution times yields maximum efficiency and throughput.
P roduct Highlights
The MPC603r microprocessor features a low-
power 2.5-volt or 3.3-volt design with three
power-saving modes—doze, nap and sleep. These
user-programmable modes progressively reduce the
power drawn by the processor. The microprocessor
also uses dynamic power management to selectively
activate functional units as they are needed by the exe-
cuting instructions. Unused functional units enter a
low-power state automatically without affecting per-
formance, software execution, or external hardware.
