BUS CONTROLLER FOR M80286 PROCESSORS

The Intel M82C288 Bus Controller is a 20-pin CHMOS III component for use in M80C286 microsystems. The M82C288 is fully compatible with its predecessor the HMOS M82288. The bus controller is fully static and supports a low power mode. The bus controller provides command and control outputs with flexible timing options. Separate command outputs are used for memory and I/O devices. The data bus is controlled with separate data enable and direction control signals.

Two modes of operation are possible via a strapping option: MULTIBUS Compatible bus cycles, and high speed bus cycles.
