MPC603/MPC604 Evaluation System—Big Bend Technical Summary

PublishTime：2021-11-24

●This document describes an evaluation system that demonstrates the capabilities of two PowerPC™ microprocessors—the MPC603 or MPC604. The system, named Big Bend, is a PowerPC Reference Platform (PReP) compliant design. The motherboard inside the Big Bend system is an 8-layer PCB design, baby AT-size (9-inch x 13-inch) form factor, and uses the MPC105 processor to PCI bridge device for core logic. Other major components on the motherboard include the UMC PCI-ISA bridge, National Semiconductor's Super I/O controllers, and NCR's SCSI controller. Big Bend provides an example that can be used in designing other systems using PowerPC microprocessors. In addition to the Big Bend evaluation system, an evaluation kit containing design information and a manufacturing kit containing in-depth manufacturing information are available.
●System Features:
