MPC8377EVRAGDA

Overview

The MPC8377EVRAGDA is a PowerQUICC II Pro System-on-Chip processor built on a 90 nm process. It integrates an e300c4s core with 32 KB instruction and data caches, operating up to 800 MHz. The device features two enhanced three-speed Ethernet controllers (eTSEC), dual PCI Express links, and two Serial ATA (SATA) controllers. Additional interfaces include USB 2.0, PCI, a 32-bit local bus, DDR1/DDR2 memory support, and an optional security engine for cryptographic acceleration.

Feature Summary

• Integrates high-speed connectivity via dual PCI Express and dual SATA controllers to reduce board space and component count.
• Includes dual enhanced three-speed Ethernet controllers supporting RGMII/MII/RMII/RTBI standards for network applications.
• Features an optional hardware security engine that offloads CPU-intensive encryption algorithms such as AES, DES, and SHA-1.
• Provides backward software compatibility with previous-generation PowerQUICC designs to facilitate migration.

Applications

• Printing systems and multifunctional printers
• Networking switches and line cards
• Wireless LANs (WLANs)
• VPN routers and network access servers
• Industrial controllers

Procurement Notes

Verify the specific ordering suffix VRAGDA against official NXP documentation to confirm package type, temperature range, and lead-free status. Confirm current manufacturing status as this product family may be subject to discontinuation notices. Ensure design-in compliance with recommended power sequencing requirements for VDD, AVDD, and I/O supplies.

Selection Notes

Select this processor for applications requiring integrated high-speed I/O without external bridge chips. The inclusion of both PCI Express and legacy PCI supports mixed-interface designs. Consider the optional security engine if hardware acceleration for IPsec or IEEE 802.11i is required. Evaluate thermal dissipation characteristics relative to the target operating frequency and ambient temperature conditions.

Part Context

This component belongs to the PowerQUICC II Pro family, designed for cost-effective, low-power communications processing. It extends the PowerQUICC portfolio by adding faster interfaces like SATA and PCI Express while maintaining software compatibility with earlier generations. The MPC837xE series includes derivatives with varying interface counts, such as the MPC8378E and MPC8379E.

Replacement Considerations

NXP recommends using Power Architecture T1013 or Arm Architecture LS1012/LS1023 families for new designs. Verify functional equivalence and pin compatibility if migrating from discontinued MPC837xE devices.
