NXP Semiconductors MPC8548EVTAVHD

Overview

MPC8548EVTAVHD from NXP Semiconductors (formerly Freescale) is a high-performance Power Architecture® e500-based integrated communications processor for embedded networking and control applications. It integrates a 1.5 GHz e500 core, 512-Kbyte L2 cache/SRAM with ECC, dual DDR2/DDR memory controller (64-bit, up to 16 GB), four enhanced three-speed Ethernet controllers (10/100/1000 Mbps), PCI Express x8, Serial RapidIO 3.125 Gbaud, and an integrated security engine supporting AES-256, SHA-256, RSA-2048, and IPsec acceleration - deployed in carrier-grade routers, industrial gateways, and secure edge servers.

For engineers reviewing the MPC8548EVTAVHD datasheet, MPC8548EVTAVHD pinout, MPC8548EVTAVHD application, or MPC8548EVTAVHD equivalent, key selection considerations include its dual-voltage I/O support (1.1 V core / 1.8–3.3 V I/O), programmable SerDes lane allocation (PCIe vs. RapidIO), hardware-accelerated crypto throughput, and thermal design at Tj = 105°C under Dhrystone load.

Technical Context

The MPC8548EVTAVHD 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 coherency module enables cache consistency across local bus, PCI, PCIe, and RapidIO masters.

Hardware acceleration is distributed across dedicated units: the Security Engine (SEC) with four crypto-channels and PKEU for RSA-2048; the XOR engine for RAID parity; and TCP/IP offload in all four eTSECs - including IPv4/v6 header checksum, VLAN tagging, jumbo frame (9.6 KB), and RMON statistics.

FAQ

What is the maximum operating frequency of the MPC8548EVTAVHD core?

The MPC8548EVTAVHD operates at a maximum core frequency of 1.5 GHz, validated under recommended conditions (VDD = 1.1 V ± 55 mV, Tj ≤ 105°C). This frequency is achieved using the e500v2 core architecture and is supported by the 133 MHz CCB platform clock driving the DDR2 interface. The MPC8548EVTAVHD datasheet specifies this rating in Table 4 (Power Characteristics) and Section 1.1 (Key Features).

Does the MPC8548EVTAVHD support DDR2 memory with ECC?

Yes, the MPC8548EVTAVHD supports full ECC on its 64-bit DDR2 memory interface, covering both data and check bits across the entire 64-bit boundary. ECC correction is implemented in hardware and applies to all memory transactions, including cache line fills and DMA transfers. This capability is documented in Section 3 (DDR and DDR2 SDRAM) of the MPC8548EVTAVHD hardware specifications.

How many Ethernet controllers does the MPC8548EVTAVHD integrate, and what speeds do they support?

The MPC8548EVTAVHD integrates four enhanced three-speed Ethernet controllers (eTSEC1–eTSEC4), each supporting 10 Mbps, 100 Mbps, and 1000 Mbps full-duplex operation. Each controller is configurable for MII, RMII, GMII, RGMII, TBI, or RTBI physical interfaces. Hardware offload includes TCP/UDP checksum, VLAN tagging, jumbo frames up to 9.6 KB, and RMON statistics - all detailed in Section 8 of the MPC8548EVTAVHD reference manual.

What cryptographic algorithms are accelerated by the Security Engine in the MPC8548EVTAVHD?

The MPC8548EVTAVHD Security Engine (SEC) accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), SHA-1/256, MD5, RSA-2048, Elliptic Curve Cryptography (F2m/Fp up to 511 bits), Kasumi F8/F9, A5/3, GEA-3, and HMAC. These are implemented in dedicated execution units (AESU, MDEU, PKEU, KEU) with four parallel crypto-channels - confirmed in Section 1.1.5 of the MPC8548EVTAVHD hardware specifications.

Is the MPC8548EVTAVHD pin-compatible with other PowerQUICC III processors like the MPC8543E or MPC8545E?

No, the MPC8548EVTAVHD is not pin-compatible with MPC8543E or MPC8545E due to differences in SerDes lane count, DDR interface width (64-bit vs. 32-bit), and security engine integration. While functional similarities exist within the PowerQUICC III family, the MPC8548EVTAVHD uses a 783-pin PBGA package with unique pin assignments for its eight PCIe lanes and dual DDR2 channels - as specified in Section 19 (Package Description) of the MPC8548EVTAVHD datasheet.
