21285 Core Logic for SA-110 Microprocessor Datasheet

The 21285 is a single-chip interface between an SA-110 microprocessor, synchronous DRAM memory (SDRAM), read-only memory (ROM), and the PCI bus. It is designed to support the following three modes of operation:

PCI-based SA-110 computer. In this configuration, the SA-110 processor is the host Intelprocessor. It configures all PCI peripherals in the system.
Attached processor. In this configuration, the SA-110 processor system interfaces directly to the host system PCI bus. The 21285 is configured by the host processor in the system.
Intelligent add-in card. In this configuration, the SA-110 processor controls a PCI-based subsystem that is designed to be plugged into a host system PCI slot. Normally, a PCI-to-PCI bridge device interfaces the oncard PCI system to the host PCI system. The SA-110 processor typically configures the devices on the add-in card. Alternatively, these devices and the 21285 can be configured by the host processor in the system.
