The MC68322 is the first of Motorola's M68000 family designed specifically for laser printers. It provides a unique solution for new designs as well as an excellent migration path for existing M68000-powered printers.
The Motorola MC68322 is a specialized integrated circuit designed specifically for laser printers. It combines an MC68000 compatible EC000 Core processor, a RISC graphics processor (RGP), and a print engine video controller (PVC) on a single chip to optimize system performance and reduce component count.
The device utilizes a unique dual bus architecture to eliminate contention between processing units, enabling parallel processing. This design supports high-resolution printing up to 600 DPI at speeds of 4-8 pages per minute while significantly reducing memory requirements through specialized banding techniques.
