Freescale Semiconductor, Inc. Fact Sheet MPC107 PCI BRIDGE MEMORY CONTROLLER The MPC107 PCI Bridge/Integrated Memory Controller provides a bridge between the INTEGRATED MEMORY CONTROLLER Peripheral Component Interconnect (PCI) bus and Motorola MPC6xx, MPC7xx, and The memory interface controls processor and PCI . MPC74xx microprocessors. PCI support allows system designers to design systems interactions to main memory. It supports a variety of . quickly using peripherals already designed for PCI and the other standard interfaces programmable timing supporting DRAM (FPM, EDO), c available in the personal computer hardware environment. The MPC107 provides many SDRAM, and ROM/Flash ROM configurations, up to n of the other necessities for embedded applications, including a high-performance speeds of 100 MHz. I , memory controller and dual-processor support; two-channel flexible DMA controller; an r interrupt controller; an I2O-ready message unit; an inter-integrated circuit controller PCI BUS SUPPORT o (I2C); and low-skew clock drivers. The MPC107 contains an Embedded Programmable The MPC107 PCI interface is designed to connect the t Interrupt Controller (EPIC) featuring five hardware interrupts (IRQs) as well as 16 serial c processor and memory buses to the PCI local bus without u interrupts along with four timers. The MPC107 uses an advanced, 2.5V HiP3 process the need for “glue” logic at speeds up to 66 MHz. The d technology and is fully compatible with TTL devices.
