MPC8240EC Datasheet Microprocessor

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: Freescale Semiconductor, Inc. Advance Information MPC8240EC Rev. 4, 11/2003 MPC8240 Integrated Processor Hardware Specifications Freescale Semiconductor, Inc... The MPC8240 combines a MPC603e core microprocessor with a PCI bridge. The MPC8240 PCI support allows system designers to rapidly create systems using peripherals already designed for PCI and the other standard interfaces. The MPC8240 also integrates a high-performance memory controller that supports various types of DRAM and ROM. The MPC8240 is the first of a family of products that provide system-level support for industry standard interfaces with PowerPC™ microprocessor cores. This hardware specification describes pertinent electrical and physical characteristics of the MPC8240. For functional characteristics of the processor, refer to the MPC8240 Integrated Processor User’s Manual (MPC8240UM). This hardware specification contains the following topics: Topic Section 1.1, “Overview” Section 1.
