NXP Semiconductors MPC8548ECVTAUJB

Overview

MPC8548ECVTAUJB from NXP Semiconductors (formerly Freescale) is a high-performance Power Architecture® e500-based integrated communications processor targeting network infrastructure and embedded control applications. It integrates a 1.0 GHz e500 core, 512-Kbyte L2 cache/SRAM with ECC, dual DDR/DDR2 memory controller (64-bit, up to 16 GB), four enhanced three-speed Ethernet controllers (10/100/1000 Mbps), integrated security engine (SEC) supporting AES-256, SHA-256, RSA-2048, and PCI Express x8 interface.

For engineers reviewing the MPC8548ECVTAUJB datasheet, MPC8548ECVTAUJB pinout, MPC8548ECVTAUJB application, or MPC8548ECVTAUJB equivalent, key selection considerations include its dual-voltage I/O support (1.1 V core / 1.8–3.3 V I/O), hardware-accelerated IPsec/SSL offload, RapidIO™ 3.125 Gbaud capability, and configurable high-speed interface multiplexing (PCIe vs. Serial RapidIO).

Technical Context

The MPC8548ECVTAUJB 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 eight-way set-associative (32-byte lines), configurable for cache-only, SRAM-only, or mixed mode, with full ECC on 64-bit boundaries and programmable line locking.

It features a dual-bus architecture: a 133 MHz local bus controller (LBC) with eight chip selects and three protocol engines (GPCM/UPM/SDRAM), and a 1066 MT/s CCB interconnect linking CPU, memory, and I/O subsystems. The integrated security engine includes dedicated execution units for AES, DES/3DES, SHA/MD5, RSA, ECC, and Kasumi, each with independent command chaining and 256-byte buffer depth.

FAQ

What is the maximum DDR2 memory capacity supported by the MPC8548ECVTAUJB?

The MPC8548ECVTAUJB supports up to 16 GB of DDR2 SDRAM using its 64-bit memory controller across four independent banks, with each bank accommodating up to 4 GB of memory. This configuration requires ×8 or ×16 DRAM devices ranging from 64 Mbits to 4 Gbits density, and fully supports registered DIMMs with on-die termination enabled for signal integrity at 400 MT/s data rates.

Does the MPC8548ECVTAUJB support PCIe Gen2 or only Gen1?

The MPC8548ECVTAUJB supports only PCI Express 1.0a specification, with maximum link speed of 2.5 GT/s per lane. It does not implement PCIe Gen2 (5.0 GT/s) or Gen3 features. Its PCIe interface is fully compliant with root complex and endpoint modes, supports x1/x2/x4/x8 link widths, and includes 256-byte maximum payload size and virtual channel 0 only - consistent with the Rev. 10 hardware specifications document.

How many independent Ethernet PHY interfaces can be configured simultaneously on the MPC8548ECVTAUJB?

The MPC8548ECVTAUJB integrates four enhanced three-speed Ethernet controllers (eTSECs), each configurable for independent PHY interfaces including GMII, RGMII, TBI, RTBI, MII, or RMII. All four eTSECs operate concurrently, enabling true quad-port 10/100/1000 Mbps Ethernet with separate MAC-layer control, VLAN tagging, and QoS queueing - verified in Section 8 of the MPC8548EEC Rev. 10 specification.

Is the MPC8548ECVTAUJB pin-compatible with other PowerQUICC III processors like the MPC8543E?

No, the MPC8548ECVTAUJB is not pin-compatible with MPC8543E or MPC8545E. While sharing the same FC-PBGA-783 package footprint, pin assignments differ significantly - particularly for high-speed interfaces (PCIe vs. RapidIO multiplexing), DDR address/control signals, and security engine debug ports. The MPC8548EEC Rev. 10 documentation explicitly states that "pinout differences" exist between family members and must be verified per device.

What boot sources are supported by the MPC8548ECVTAUJB's integrated boot sequencer?

The MPC8548ECVTAUJB boot sequencer supports loading initial configuration and firmware exclusively from serial ROM devices connected via the dual I2C controllers, using extended 10-bit addressing mode. It performs CRC-16 validation on loaded data and supports preamble signature checking. No NAND/NOR flash, SPI, or parallel ROM boot modes are implemented - this is confirmed in Section 1.2.2 of the MPC8548EEC Rev. 10 specification.
