The F14 CADC was NOT multichip. This is a cannard put out by the pro-Intel forces to attempt to discredit the CADC as being a microprocessor developed before the 4004. The only thing the CADC did NOT have that the Intel 4004 does is a program counter. The program counter in the CADC architecture was placed on the RAS (Random Access Storage, otherwise known as RAM) and ROM chips to facilitate multi-tasking/processing. A PC could have easily been implemented on the primary processor but this was a pratical design decision only.

There is also the Four Phase Systems AL8, which preceded the CADC by a couple years, and may well have also been a single-chip 8-bit microprocessor, but it was intended to be utilized as an 8-bit slice of a 24-bit architecture.
