Description:
The Intel D82288 Bus Controller is a 20 pin HMOS component for
use in M80286 microsystems. 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 I compatible bus cycles, and high speed bus cycles.
The M82288 device has been replaced with the 82C288.
