The IXP1250 interfaces to a maximum of 256 Mbytes of SDRAM over a 64-bit data bus.
A separate 32-bit SRAM bus supports up to 8 Mbytes of SSRAM and 8 Mbytes of BootRom.
The SRAM Bus also supports memory-mapped I/O devices within a 2 Mbyte memory space.
A 32-bit PCI interface supports interfacing with industry-standard PCI devices.
The IX Bus, a flexible 64-bit or dual 32-bit interface, supports attachment of MACs, framers,
custom logic devices, and an additional IXP1250.
An asynchronous serial interface is supported for a debugger console over an RS-232 link.
An IEEE 1149.1 interface is supported for Boundary Scan testing.
