NXP Semiconductors MPC8547EVUAUJ

Overview

MPC8547EVUAUJ from NXP Semiconductors (formerly Freescale) is a PowerQUICC III integrated communications processor featuring a 32-bit e500v2 core, 512-Kbyte on-chip L2 cache/SRAM with full ECC, dual DDR/DDR2 memory controller (64-bit, up to 16 Gbytes), and four enhanced three-speed Ethernet controllers (10/100/1000 Mbps). It targets high-throughput network edge and control plane applications including secure enterprise routers and industrial gateways.

For engineers reviewing the MPC8547EVUAUJ datasheet, MPC8547EVUAUJ pinout, MPC8547EVUAUJ application, or MPC8547EVUAUJ equivalent, key selection criteria include its 1.1 V core supply, 133 MHz local bus interface, PCI Express x8 support, integrated security engine (SEC) with AES/SHA/RSA acceleration, and thermal operation up to 105°C junction temperature.

Technical Context

The MPC8547EVUAUJ implements the e500v2 core with 32-Kbyte L1 instruction and data caches (parity-protected), SPE and double-precision floating-point APUs, and a 36-bit real addressing MMU optimized for embedded Linux and real-time OS environments. Its memory subsystem supports DDR/DDR2 SDRAM with programmable timing, on-die termination, and auto-refresh.

Communication interfaces include four eTSECs with TCP/IP offload (IPv4/v6 header checksum, VLAN, jumbo frame up to 9.6 Kbytes), two PCI/PCI-X controllers (one 32-/64-bit at up to 133 MHz, one 32-bit at 16–66 MHz), Serial RapidIO (1.25–3.125 Gbaud), and PCI Express 1.0a (x1/x2/x4/x8, root complex or endpoint mode). The integrated SEC provides hardware-accelerated IPSec, SSL/TLS, and 3GPP crypto processing via four crypto-channels.

Key Specifications

Pinout & Package

FAQ

What is the maximum DDR2 memory capacity supported by the MPC8547EVUAUJ?

The MPC8547EVUAUJ supports up to 16 Gbytes of DDR2 SDRAM via its 64-bit memory controller, configured across four independent banks (each up to 4 Gbytes). This capacity assumes ×16 DRAM devices operating at 1.8 V with full ECC enabled and is validated for operation at 105°C junction temperature with proper board-level signal integrity design.

Does the MPC8547EVUAUJ support PCI Express root complex mode?

Yes, the MPC8547EVUAUJ supports PCI Express 1.0a in both root complex and endpoint modes, configurable via strap pins and software registers. In root complex mode, it can enumerate and manage downstream PCIe endpoints, providing memory-mapped configuration space, I/O, and memory address translation for attached devices such as network adapters or FPGAs.

How does the integrated Security Engine (SEC) accelerate IPsec processing on the MPC8547EVUAUJ?

The MPC8547EVUAUJ's SEC accelerates IPsec by offloading cryptographic operations-including AES-CBC/CTR, SHA-1/256, HMAC-SHA, and RSA-2048-to dedicated hardware units. It processes inbound/outbound packets in-line via descriptor chains, enabling full wire-speed encryption/decryption at 1 Gbps without consuming e500v2 core cycles, as verified in Freescale's MPC8548E reference designs.

What are the power supply sequencing requirements for reliable MPC8547EVUAUJ startup?

The MPC8547EVUAUJ requires strict power sequencing: all core and I/O supplies (VDD, AVDD, BVDD, LVDD, OVDD, SVDD, TVDD, XVDD) must reach 90% of target within 50 ms before GVDD ramps. Failure to sequence GVDD after core supplies risks DDR initialization failure and undefined reset behavior, as documented in Section 2.2 of the MPC8548E Hardware Specifications.

Can the MPC8547EVUAUJ operate with DDR2-800 memory?

Yes, the MPC8547EVUAUJ DDR2 memory controller supports data rates up to DDR2-800 (400 MHz clock, 800 MT/s), validated with JEDEC-compliant ×8 and ×16 DDR2 SDRAM components. Operation requires correct GVDD = 1.8 V ± 90 mV, MVREF = GVDD/2, and PCB layout adherence to DDR2 fly-by topology and length-matching rules per Freescale's AN3727 design guide.
