Exposure to absolute maximum rating conditions for extended periods may affect reliability.


Description

The IDT79RC32134 is a high performance system controller chip that supports IDT's RISCore32300 CPU family. The RC32134 offers a direct connection to IDT's RC32364 32-bit embedded microprocessor. The RC32134 provides the system logic for boot memory, main memory, I/O, and PCI. It also includes on-chip peripherals such as DMA channels, reset circuitry, interrupts, timers, and UARTs. Together, the RC32364 CPU and the RC32134 system controller form a complete CPU subsystem for embedded designs.

Figure 1 illustrates the typical system implementation, based on the RC32364 CPU and the RC32134 system controller. The RC32134 interfaces directly to the RC32364 and provides all of the necessary control and address signals to drive the external memory and I/O. Note that, depending on the loading of the CPU data bus, external data buffers could be used to reduce the loading and isolate different memory regions. As illustrated in the system block diagram, the memory and I/O data path is external to the RC32134.
