NXP Semiconductors MPC8568VTAUJJ

Overview

MPC8568VTAUJJ from NXP Semiconductors (formerly Freescale) is a PowerQUICC III integrated communications processor featuring a 32-bit e500v2 Power Architecture core, 512 KB L2 cache/SRAM, dual 10/100/1000-Mbps eTSEC Ethernet controllers, DDR/DDR2 memory controller, and integrated QUICC Engine™ for protocol offload. It targets high-reliability network edge infrastructure including enterprise routers, carrier-grade access gateways, and secure VPN appliances.

For engineers reviewing the MPC8568VTAUJJ datasheet, MPC8568VTAUJJ pinout, MPC8568VTAUJJ application, or MPC8568VTAUJJ equivalent, key selection considerations include its dual eTSECs with TCP/IP acceleration, x1/x4 PCI Express + Serial RapidIO I/O flexibility, hardware security engine supporting IPSec/SSL/TLS, and 36-bit physical addressing for scalable memory mapping in embedded networking systems.

Technical Context

The MPC8568VTAUJJ implements a coherent e500v2 core with double-precision floating-point APU and embedded vector/scalar single-precision FP units, coupled to an 8-way set-associative 512 KB L2 cache configurable as SRAM. Its coherency module (ECM) enables snooping between CPU and I/O masters across local and external address spaces via ATMUs supporting 64-bit PCI Express and RapidIO environments.

Its QUICC Engine provides eight UCCs supporting up to eight 10/100-Mbps MII/RMII ports, three 1-Gbps GMII/RGMII/TBI interfaces, ATM SAR up to OC-12, HDLC/Transparent (256 channels), and IP termination for IPv4/IPv6 - all managed independently of the main e500 core. The integrated Security Engine includes PKEU, DEU, AESU, MDEU, KEU, RNG, and XOR units enabling single-pass SSL 3.0/TLS 1.0, IPSec, and 802.11i processing.

Key Specifications

FAQ

What is the maximum DDR2 memory capacity supported by the MPC8568VTAUJJ?

The MPC8568VTAUJJ supports up to 16 GB of main memory via its DDR/DDR2 SDRAM controller. This is achieved using four chip select signals, bank sizes ranging from 64 MB to 4 GB, and 16 multiplexed address lines supporting densities up to 4 Gbit per device. ECC protection is integrated for single-bit correction and double-bit detection.

Does the MPC8568VTAUJJ support both PCI Express and Serial RapidIO simultaneously?

Yes, the MPC8568VTAUJJ supports simultaneous operation of x1/x2/x4 PCI Express and 1x/4x Serial RapidIO, but with constraints: both share the same clock source and are limited to 2.5 Gbaud per lane; spread-spectrum clocking is disabled when RapidIO is active. An x8 PCI Express configuration disables RapidIO due to pin multiplexing limitations.

How does the QUICC Engine in the MPC8568VTAUJJ differ from the main e500v2 core?

The QUICC Engine is a separate, autonomous RISC-based coprocessor with eight Universal Communication Controllers (UCCs), independent of the e500v2 core. It handles time-critical protocol processing - including ATM SAR, HDLC, PPP, and Ethernet framing - freeing the e500v2 to run the OS and control-plane software. They communicate via shared memory and doorbell interrupts, not shared execution resources.

What cryptographic algorithms are accelerated by the Security Engine in the MPC8568VTAUJJ?

The MPC8568VTAUJJ Security Engine accelerates DES, 3DES, AES (128/192/256-bit), SHA-1, MD5, HMAC-SHA1, RSA (up to 2048-bit via PKEU), Kasumi, and random number generation. It supports single-pass processing for compound operations like 3DES-HMAC-SHA1 and is validated for SSL 3.0/TLS 1.0, IPSec ESP/AH, SRTP, and 802.11i WPA2.

Is the MPC8568VTAUJJ pin-compatible with the MPC8567E series?

No, the MPC8568VTAUJJ is not pin-compatible with the MPC8567E. Although both share the same 783-pin PBGA package footprint, their pin assignments differ significantly - particularly for eTSEC1/eTSEC2, TLU, and RapidIO/PCIe signal routing. The MPC8567E omits eTSEC1, eTSEC2, and TLU entirely, and supports only x1/x2/x4 PCIe (no x8), confirming distinct pinout definitions per device.
