MPC8378CVRALG

Overview

The MPC8378CVRALG is a microprocessor from the PowerQUICC II Pro family, built on the 32-bit superscalar e300 core. It operates at frequencies up to 667 MHz and integrates dual Gigabit Ethernet controllers with SGMII support. The device includes two PCI Express interfaces supporting x1 or x2 widths, integrated SATA controllers for storage applications, and USB 2.0 capabilities. It features 32 KB L1 data and instruction caches, a DDR/DDR2 memory controller, and an optional integrated security engine.

Feature Summary

• Integrates dual Gigabit Ethernet controllers with SGMII interface support
• Includes two PCI Express interfaces for high-speed I/O connectivity
• Features integrated Serial-ATA (SATA) controllers for storage solutions
• Provides an optional hardware security engine for encryption

Applications

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

Procurement Notes

Verify the specific suffix 'E' in the part number against official documentation to confirm the presence of the integrated security engine, as this feature is explicitly designated as optional within the MPC837x family specifications. Ensure compatibility with required DDR memory types and interface standards before procurement.

Selection Notes

Select this component for designs requiring high integration of networking and storage controllers on a single chip. The e300 core offers software compatibility with legacy 603e products. Consider the availability of the security engine if cryptographic functions are required, noting that it is not standard across all variants.

Part Context

This processor belongs to the MPC837x family, which utilizes a 90 nm process technology. The family is designed to address SMB and consumer application needs by reducing external controller requirements through high integration of PCI Express, SATA, and Ethernet interfaces.

Replacement Considerations

MPC8377E and MPC8379E are confirmed substitutes within the same family.
