The peripheral logic integrates a PCI bridge, dual universal asynchronous receiver/transmitter (DUART),
memory controller, DMA controller, PIC interrupt controller, a message unit (and I

support, memory management, a 16-Kbyte instruction cache, a 16-Kbyte data cache, and power
management features. The integration reduces the overall packaging requirements and the number of
discrete devices required for an embedded system.
An internal peripheral logic bus interfaces the processor core to the peripheral logic. The core can operate
at a variety of frequencies, allowing the designer to trade off performance for power consumption. The
processor core is clocked from a separate PLL that is referenced to the peripheral logic PLL. This allows
the microprocessor and the peripheral logic block to operate at different frequencies while maintaining a
synchronous bus interface. The interface uses a 64- or 32-bit data bus (depending on memory data bus
width) and a 32-bit address bus along with control signals that enable the interface between the processor
and peripheral logic to be optimized for performance. PCI accesses to the MPC8245 memory space are
passed to the processor bus for snooping when snoop mode is enabled.
The general-purpose processor core and peripheral logic serve a variety of embedded applications. The
MPC8245 can be used as either a PCI host or PCI agent controller.
