Description
The FC1698-QF-AC is an electronic component model in the IC Chips product category. It is a full 32-bit implementation of the M68000 family of microprocessors from Motorola. The MC68020 is implemented with 32-bit registers and data paths, 32-bit addresses, a rich instruction set, and versatile addressing modes. It is object-code compatible with earlier members of the M68000 family and has new addressing modes for enhanced support of high-level languages. The MC68020 also features an on-chip instruction cache, a flexible coprocessor interface with full IEEE floating-point support, and parallel operation capabilities.
