NXP Semiconductors MPC8547EVJAQGD

Overview

MPC8547EVJAQGD from NXP Semiconductors (formerly Freescale) is a PowerQUICC III integrated communications processor featuring an e500v2 32-bit Power Architecture 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 routing, secure gateway, and industrial control applications requiring hardware-accelerated crypto and deterministic I/O.

For engineers reviewing the MPC8547EVJAQGD datasheet, MPC8547EVJAQGD pinout, MPC8547EVJAQGD application, or MPC8547EVJAQGD 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-256/SHA-256/RSA-2048, and 105°C junction temperature rating for extended thermal operation.

Technical Context

The MPC8547EVJAQGD implements the e500v2 core with 32-Kbyte L1 instruction and data caches (parity-protected), SPE and double-precision FPU APUs, and 36-bit real addressing. Its memory subsystem includes programmable DDR/DDR2 timing, on-die termination for DDR2, and battery-backed memory support.

It integrates dual I²C controllers, DUART with 16550 compatibility, four eTSECs with TCP/IP offload (IPv4/IPv6 checksum, VLAN, jumbo frames), and a 4-channel DMA controller with scatter-gather and misaligned transfer support. The device supports PCI Express 1.0a (x8/x4/x2/x1), Serial RapidIO 1.2 (1.25–3.125 Gbaud), and OCeaN switch fabric for packet reordering and starvation avoidance.

Key Specifications

Pinout & Package

FAQ

What is the maximum DDR2 data rate supported by the MPC8547EVJAQGD?

The MPC8547EVJAQGD supports DDR2 SDRAM up to 800 MT/s (400 MHz clock), enabled by its 64-bit DDR2 memory controller with programmable timing, on-die termination, and auto-refresh capability. This allows sustained bandwidth of up to 6.4 GB/s in dual-channel configurations when paired with compatible DIMMs, as confirmed in Section 6 of the MPC8548EEC Rev. 10 specification document.

Does the MPC8547EVJAQGD support PCI Express root complex mode?

Yes, the MPC8547EVJAQGD supports configurable PCI Express operation as either root complex or endpoint, per Section 17 of the MPC8548EEC Rev. 10 datasheet. This enables flexible system topology design-such as hosting add-in cards in root mode or connecting as a peripheral in endpoint mode-without requiring external bridge logic.

How many cryptographic algorithms does the integrated security engine (SEC) in the MPC8547EVJAQGD support?

The MPC8547EVJAQGD's integrated SEC supports AES (128/192/256-bit keys), SHA-1/SHA-256, MD5, RSA (up to 2048-bit), ECC (F2m/Fp up to 511-bit), KEU (Kasumi F8/F9), AFEU (ARC4), and RNG-all detailed in Section 5 of the MPC8548EEC Rev. 10 specification. These are implemented in dedicated execution units enabling concurrent algorithm processing.

What is the function of the OCeaN switch fabric in the MPC8547EVJAQGD?

The OCeaN switch fabric in the MPC8547EVJAQGD is a full-crossbar packet switch that reorders packets based on priority, bypasses blocked paths to avoid deadlock, implements starvation avoidance, and supports payloads up to 256 bytes. It interconnects internal high-speed peripherals-including eTSECs, RapidIO, and PCI Express-enabling deterministic, low-latency data movement without CPU arbitration.

Can the MPC8547EVJAQGD operate with DDR and DDR2 memory simultaneously?

No, the MPC8547EVJAQGD's DDR/DDR2 memory controller operates in either DDR or DDR2 mode-not concurrently. Mode selection is configured at boot via POR configuration bits and fixed for runtime; mixing DRAM types on the same 64-bit bus is not supported due to incompatible signaling standards (SSTL_2 vs. SSTL_1.8) and timing requirements.
