NXP Semiconductors MPC8547EHXAUJ

Overview

MPC8547EHXAUJ from NXP Semiconductors (formerly Freescale) is a Power Architecture®-based integrated communications processor featuring an e500v2 core, 512-Kbyte L2 cache/SRAM, DDR/DDR2 memory controller, four eTSEC Ethernet controllers, PCI Express, Serial RapidIO, and integrated security engine (SEC). It operates at up to 1.5 GHz core frequency and targets high-performance networking and telecom infrastructure applications including enterprise routers, wireless baseband units, and secure gateways.

For engineers reviewing the MPC8547EHXAUJ datasheet, MPC8547EHXAUJ pinout, MPC8547EHXAUJ application, or MPC8547EHXAUJ equivalent, key selection criteria include its dual-voltage I/O support (1.1 V core / 1.8–3.3 V I/O), 133 MHz local bus interface, 64-bit DDR2 SDRAM controller with ECC, and hardware-accelerated IPsec/SSL/TLS processing via the SEC v3.2 engine.

Technical Context

The MPC8547EHXAUJ implements the e500v2 core with 32-Kbyte L1 instruction and data caches (parity-protected), 36-bit real addressing, and MMU supporting 4-Kbyte to 4-Gbyte page sizes. Its L2 cache/SRAM is configurable as 512-Kbyte unified cache (eight-way set-associative, 32-byte lines) or SRAM with byte-accessible ECC and snoopable regions for I/O coherency.

It integrates dual PCI/PCI-X controllers (one 32-/64-bit up to 133 MHz, one 32-bit up to 66 MHz), a PCI Express 1.0a x8 interface (root complex or endpoint mode), and a 4× Serial RapidIO™ interface compliant with Revision 1.2 at 1.25/2.5/3.125 Gbaud per lane. The security engine supports AES-128/192/256, SHA-1/256, RSA-2048, and elliptic curve cryptography with dedicated PKEU, AESU, and MDEU units.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MPC8547EHXAUJ core?

The MPC8547EHXAUJ operates at a maximum core frequency of 1.5 GHz, validated under typical conditions (VDD = 1.1 V, Tj = 105°C). This frequency enables high-throughput packet processing in networking applications while maintaining thermal compliance in standard convection-cooled enclosures. The MPC8547EHXAUJ achieves this performance using the e500v2 core with dual-issue superscalar execution and integrated L2 cache.

Does the MPC8547EHXAUJ support DDR2 memory with ECC?

Yes, the MPC8547EHXAUJ DDR/DDR2 memory controller fully supports ECC on 64-bit data transfers. It implements chipkill-capable ECC protection for single-bit error correction and double-bit error detection across the entire 64-bit interface. ECC is enabled via configuration registers and applies to both DDR and DDR2 modes, with GVDD set to 1.8 V ± 90 mV for DDR2 operation. The MPC8547EHXAUJ uses this ECC to ensure data integrity in mission-critical telecom and industrial applications.

How many Ethernet controllers does the MPC8547EHXAUJ integrate, and what speeds do they support?

The MPC8547EHXAUJ integrates four enhanced three-speed Ethernet controllers (eTSECs), each supporting 10/100/1000 Mbps full-duplex operation. They comply with IEEE 802.3, 802.3u, 802.3z, and 802.3ab standards and support multiple physical interfaces including GMII, RGMII, MII, RMII, TBI, and RTBI. Each eTSEC includes hardware TCP/IP offload for checksum generation/verification, VLAN insertion/deletion, and jumbo frames up to 9.6 KB - all essential features for the MPC8547EHXAUJ's role in multi-port networking equipment.

What cryptographic algorithms are accelerated by the MPC8547EHXAUJ security engine?

The MPC8547EHXAUJ integrates the SEC v3.2 security engine, which accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), SHA-1/256, MD5, RSA-2048, Diffie-Hellman, elliptic curve cryptography (F2m/Fp up to 511 bits), and Kasumi (F8/F9). These algorithms are executed in dedicated hardware units (AESU, MDEU, PKEU, KEU) with four independent crypto-channels, enabling concurrent processing of IPsec, SSL/TLS, and 3GPP security protocols. The MPC8547EHXAUJ uses this acceleration to sustain encrypted throughput exceeding 1 Gbps without burdening the e500v2 core.

Is the MPC8547EHXAUJ pin-compatible with other PowerQUICC III processors?

Yes, the MPC8547EHXAUJ shares the same 1296-ball PBGA package and pinout as the MPC8548EHXAUJ and MPC8545EHXAUJ, enabling direct PCB footprint compatibility within the PowerQUICC III family. This allows design reuse across performance tiers - for example, upgrading from MPC8547EHXAUJ to MPC8548EHXAUJ requires only firmware and minor BIOS updates, with no PCB redesign. However, functional differences (e.g., presence/absence of Serial RapidIO or fifth eTSEC) must be validated in software. The MPC8547EHXAUJ maintains this compatibility while delivering optimized feature balance for mid-range applications.
