The PPS-4/1 (Parallel Processing System - 4-bit word - 1 chip) was a family of 4-bit microcontrollers chips designed by Rockwell International and introduce in 1st quarter of 1976. The PPS-4/1 is the third iteration of the original PPS-4. The PPS-4/1 were architecturally identical to the PPS-4 and PPS-4/2 with the addition of a clock generator and program memory incorporated internally, making it a single-chip system (hence the "/1"). It's full compatible with all the original PPS-4 CPU and all the other parts.

Members

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).
