MPC8378VRALGA

Overview

The NXP MPC8378VRALGA is a PowerQUICC II Pro microprocessor based on the 90 nm e300 core. It operates at frequencies up to 800 MHz and features a 32-bit architecture with dual integer units and a floating-point unit. The device integrates two Gigabit Ethernet controllers, PCI Express interfaces supporting x1 or x2 widths, and Serial-ATA (SATA) controllers compatible with SATA I and II standards. It includes a 32 KB L1 data and instruction cache, a DDR/DDR2 memory controller, and an optional integrated security engine for cryptographic acceleration.

Feature Summary

• Integrates high-performance e300 cores with floating-point capabilities for computational efficiency
• Combines dual Gigabit Ethernet ports with PCI Express and Serial-ATA controllers for reduced component count
• Includes an integrated security engine supporting various encryption algorithms and hardware acceleration

Applications

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

Procurement Notes

Verify the specific suffix 'VRALGA' against official NXP documentation to confirm frequency, package type, and security feature availability. Confirm current lifecycle status as older MPC837x variants may be discontinued. Ensure compatibility with existing board designs regarding voltage levels and pin configurations before procurement.

Selection Notes

Select this processor for applications requiring high integration of networking and storage interfaces within a single chip. The e300 core offers software compatibility with legacy 603e products. Consider the integrated security engine if cryptographic offloading is required. Evaluate the trade-off between the integrated SATA/PCIe solution and discrete controller alternatives for cost and space optimization.

Part Context

The MPC8378VRALGA belongs to the MPC837xE family of PowerQUICC II Pro processors. This family targets SMB and consumer applications by providing a System-on-Chip solution that simplifies board design. It shares architectural similarities with the MPC8377E and MPC8379E but differs in specific interface configurations such as the number of SATA ports and Ethernet PHY types.

Replacement Considerations

NXP recommends using Power Architecture T1013 or Arm Architecture LS1012/LS1023 families for new designs instead of the MPC837x series.
