PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Overview
The peripheral logic integrates a PCI bridge, memory controller, DMA controller, EPIC interrupt controller,
I2O controller, and an I
2C controller. The 603e core is a full-featured, high-performance processor with
oating-point support, memory management, 16-Kbyte instruction cache, 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.
The MPC8240 contains an internal peripheral logic bus that interfaces the 603e 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 603e core is clocked from a separate PLL, which 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 MPC8240’s memory
space are passed to the processor bus for snooping purposes when snoop mode is enabled.
The MPC8240’s features serve a variety of embedded applications. In this way, the 603e core and peripheral
logic remain general-purpose. The MPC8240 can be used as either a PCI host or an agent controller.
