NXP Semiconductors MPC8548VTAUJD

Overview

MPC8548VTAUJD 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, dual PCI/PCI-X interfaces, PCI Express x8, Serial RapidIO™, and integrated security engine (SEC). It operates at up to 1.5 GHz core frequency and targets high-throughput network infrastructure applications including enterprise routers, wireless baseband units, and secure gateways.

For engineers reviewing the MPC8548VTAUJD datasheet, MPC8548VTAUJD pinout, MPC8548VTAUJD application, or MPC8548VTAUJD equivalent, key selection criteria include its dual 32-bit PCI/PCI-X support with 133 MHz capability, 64-bit DDR2 interface with full ECC, hardware-accelerated IPsec/SSL/TLS via SEC, and flexible I/O multiplexing between PCI Express and RapidIO configurations.

Technical Context

The MPC8548VTAUJD 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 in eight-way set-associative mode with ECC on 64-bit boundaries and supports stashing for external master-initiated allocation.

It integrates a programmable ATMU with eight local access windows, inbound/outbound translation for PCI/PCI-X, PCI Express, and RapidIO, and a DDR/DDR2 controller supporting up to 16 Gbytes across four banks with on-die termination (DDR2), auto-refresh, and battery-backed memory support.

FAQ

What is the maximum DDR2 data rate supported by the MPC8548VTAUJD?

The MPC8548VTAUJD DDR2 interface supports data rates up to 800 MT/s (400 MHz clock), enabled by its 64-bit bus width and programmable timing parameters. This allows peak theoretical bandwidth of 6.4 GB/s, sufficient for high-throughput control-plane and packet buffering in multi-gigabit routers. The controller also supports registered DIMMs and on-die termination to maintain signal integrity at these speeds. MPC8548VTAUJD's DDR2 implementation complies with JEDEC standards and includes full ECC for error detection and correction.

Does the MPC8548VTAUJD support PCI Express root complex mode?

Yes, the MPC8548VTAUJD supports PCI Express root complex mode, as confirmed in Section 17 of the MPC8548EEC hardware specification. It can be configured as either root complex or endpoint via software-controlled configuration registers. In root complex mode, it provides memory-mapped configuration space, supports Type 0 and Type 1 configuration transactions, and manages downstream link training. MPC8548VTAUJD implements PCI Express 1.0a with x1/x2/x4/x8 link widths and auto-detection of connected lanes, making it suitable for host-side expansion in networking blades.

How many independent Ethernet MACs does the MPC8548VTAUJD integrate?

The MPC8548VTAUJD integrates four independent enhanced three-speed Ethernet controllers (eTSECs), each with full MAC functionality, configurable PHY interface support (MII/GMII/RGMII/RTBI/RMII), and hardware offload engines. Each eTSEC has dedicated 10-Kbyte TX and 2-Kbyte RX FIFOs, supports jumbo frames up to 9.6 KB, and provides per-port VLAN insertion/deletion and QoS queueing. MPC8548VTAUJD's eTSECs operate concurrently and independently, enabling true quad-port 1 Gbps line-rate forwarding in layer-2/3 switching applications.

What cryptographic algorithms are accelerated by the MPC8548VTAUJD's Security Engine (SEC)?

The MPC8548VTAUJD's integrated Security Engine (SEC) accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), SHA-1/SHA-256, MD5, HMAC, RSA up to 2048-bit, elliptic curve cryptography (F2m/Fp up to 511 bits), KEA/Kasumi (F8/F9), and ARC4 stream cipher. It also includes a hardware random number generator (RNG) and XOR engine for RAID parity. MPC8548VTAUJD's SEC processes these algorithms in parallel across four crypto-channels, enabling wire-speed IPsec and SSL/TLS termination without CPU overhead.

Is the MPC8548VTAUJD pin-compatible with other PowerQUICC III family members like the MPC8543E?

No, the MPC8548VTAUJD is not pin-compatible with MPC8543E or MPC8545E due to differences in I/O count, ball map, and power delivery requirements. While the families share architectural similarities and software compatibility, MPC8548VTAUJD uses a 783-ball TBGA package with distinct power rail assignments (e.g., separate SVDD/XVDD for SerDes), whereas MPC8543E uses a smaller 672-ball package. Pinout differences are explicitly noted in the MPC8548EEC specification under "Package Description" and "Pin Multiplexing" sections. MPC8548VTAUJD requires its own PCB layout and power delivery design.
