PA-7200

The PA-7200 – also known as PCX-T', code-named Thunderbird' –, is a microprocessor that implements the PA-RISC 1.1 instruction set architecture (ISA) developed by Hewlett-Packard (HP).

The second integer unit was not identical to the first, and was only capable of executing simple but more frequently used instructions.

[1] It was fabricated by Hewlett-Packard in their CMOS14A process which they co-developed with Analog Devices.

The microprocessor uses an unusual 4.4 V power supply as a result of its development.

A 3.3 V power supply did not enable the microprocessor to achieve the intended clock frequency, so 4.4 V was chosen as a compromise.
