The MC68020RC20E is the first full 32-bit implementation of the M68000 family of microprocessors from Motorola. Using VLSI technology, the MC68020RC20E is implemented with 32-bit registers and data paths, 32-bit addresses, a rich instruction set, and versatile addressing modes. The MC68020RC20E is object-code compatible with earlier members of the M68000 family and has the added features of new addressing modes in support of high-level languages, an on-chip instruction cache, and a flexible coprocessor interface with full IEEE floating-point support (the MC68881 and MC68882).
