10 Facts About PowerPC 601

PowerPC 601 was the first generation of microprocessors to support the basic 32-bit PowerPC instruction set.

The PowerPC 601 used the IBM CMOS-4s process and the PowerPC 601+ used the IBM CMOS-5x process.

The PowerPC 601+ design was remapped from CMOS-4s to CMOS-5x by an IBM-only team.

PowerPC 601 603 was the first processor implementing the complete 32-bit PowerPC 601 Architecture as specified.

The PowerPC 601 603e is still sold today by IBM and Freescale, and others like Atmel and Honeywell who makes the radiation hardened variant RHPPC.
