MPC8378CVRALGA

Overview

The MPC8378CVRALGA is a PowerQUICC II Pro microprocessor featuring the e300c4s core, operating at 667 MHz. It utilizes a 90 nm process and integrates dual Gigabit Ethernet controllers with SGMII support, PCI Express (2x1 or 1x2), and Serial-ATA (SATA) controllers. The device includes DDR/DDR2 memory controllers supporting up to 400 MHz data rates, USB 2.0, and standard I/O interfaces like SPI and I2C. It is housed in a 689-BBGA package.

Feature Summary

• Integrates dual Gigabit Ethernet controllers with SGMII interface for high-speed networking connectivity.
• Includes integrated PCI Express and Serial-ATA controllers to reduce external component requirements.
• Features an e300 core built on Power Architecture technology with floating-point capabilities.
• Supports multiple memory types including DDR and DDR2 via integrated controllers.

Applications

• Wireless access points
• Network attached storage
• Small-to-medium business routers

Procurement Notes

Verify the specific suffix 'V' against official documentation to confirm voltage and temperature specifications. Confirm the part status as obsolete before procurement planning. Ensure compatibility with existing board designs referencing the 689-BBGA package dimensions. Cross-reference errata documents for known silicon revisions prior to implementation.

Selection Notes

Select this component when a single-chip solution combining networking, storage, and processing is required. The integration of SATA and PCIe reduces bill-of-materials complexity compared to discrete controller approaches. Verify that the 667 MHz operating frequency meets system performance requirements. Ensure the design supports the necessary DDR/DDR2 memory configurations.

Part Context

This part belongs to the MPC837x family of PowerQUICC II Pro processors. The family shares the e300 core architecture but varies in peripheral integration, such as the presence of SATA controllers in the MPC8378 variant. These devices are designed for cost-effective, highly integrated communication applications.
