The F-11 chip set (code-named 'Fonz') was DEC's second microprocessor implementation of the PDP-11 architecture. It was used in the KDF11 CPUs.
The main CPU was implemented in two chips (carried on a single DIP carrier): the data paths chip (DC302, DEC part # 21-15541-Ax, where x is a capital letter giving the revision; B is the most common, although C has been seen), which contains the registers, ALU, etc; and the control chip (DC303, DEC part # 23-001C7-Ax, although only the A revision has been seen), which contains microcode and a small amount of miscellaneous logic.
Unlike the first microprocessor implementation (the LSI-11), the F-11 chip set implemented the full PDP-11 architecture, including the optional KTJ11-A memory management chip which implemented standard PDP-11 Memory Management, and the optional KEF11-A floating point chip which implemented the FP11-compatible floating point.
(The KEF11-A requires the KTJ11-A, since the floating point registers are actually in the KTJ11-A; probably because the KEF11-A is microcode, and there aren't enough pins for both the data bus, and the microcode bus.)
There is also a 6-chip carrier implementing the PDP-11 Commercial Instruction Set (CIS).
