The PPS-4 (Parallel Processing System - 4-bit word) was a family of 4-bit microprocessor chips designed by Rockwell International and introduce in 3rd quarter of 1972.

The original PPS-4 chipset was designed to provide complete functionality in three chips - CPU, program memory, and a clock generator. A later version known as the PPS-4/2 ("/2" denoting a two-chip system) eliminated the external clock generator chip by incorporating it internally. A third variation known as the PPS-4/1 ("/1" being a single-chip microcomputer) was actually a microcontroller, including the program memory internally.

PPS-4/1 microcontrollers

Rockwell expanded the family by introducing the PPS-4/1 which is a microcontroller incorporating the PPS-4 CPU, the program memory, and clock generator internally. The PPS-4/1 were considerably slower than their multi-chip counterparts, operating at only up to half of their frequency (40 KHz-100 KHz).
