PC740A/PC750AFS - Rev.1 – 01/11
PC740A and 750APowerPC™ Microprocessors
Fact Sheet
The PowerPC 750 and PowerPC740 microprocessors are low-power 32-bit implementations of the PowerPC Reduced
Instruction Set Computer (RISC) architecture. The PowerPC 750 and the PowerPC 740 micro-processors differ only in that
the PowerPC 750 features a dedicated L2 cache interface with on-chip L2 tags.
Both are software -compatible and bus-compatible with the PowerPC603e
TM
micro -processor families, and the PowerPC
740 is pin-compatible as well. PowerPC 750/740 micro-processors are fully JTAG
-compliant.
