Product details
Overview
MPC8568ECVTAQGG 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 carrier-grade networking equipment including edge routers, media gateways, and secure VPN appliances.
For engineers reviewing the MPC8568ECVTAQGG datasheet, MPC8568ECVTAQGG pinout, MPC8568ECVTAQGG application, or MPC8568ECVTAQGG equivalent, key selection criteria include its dual eTSEC with TCP/IP acceleration, x1/x2/x4 PCI Express + Serial RapidIO coexistence, 36-bit physical addressing, integrated security engine (SEC) supporting SSL/TLS/IPSsec in single pass, and support for up to 16 GB DDR2 main memory.
Technical Context
The MPC8568ECVTAQGG implements a dual-bus architecture: the e500v2 core interfaces via an on-chip coherency module (ECM) to 512 KB configurable L2 cache/SRAM, while I/O subsystems-including eTSEC, PCI Express, RapidIO, and QUICC Engine-are connected through a high-bandwidth crossbar. Its DDR2 controller supports 16 GB addressable memory with ECC, page-mode optimization, and dynamic power management via MCKE assertion.
It integrates two independent eTSECs compliant with IEEE 802.3/802.3u/802.3z/802.3ab, each with 2 KB RX and 10 KB TX FIFOs, hardware VLAN tagging, jumbo frame support (≤9.6 KB), and full TCP/IP header checksum offload. The QUICC Engine provides eight UCCs supporting HDLC, TDM, ATM SAR, PPP, and multi-protocol Ethernet switching, decoupled from the main CPU for deterministic real-time processing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8567ECVTAQGG | Lacks eTSEC1/eTSEC2 and TLU; no security engine; PCI Express limited to x1/x2/x4 (no x8); no Serial RapidIO | Suitable for cost-sensitive, lower-bandwidth control-plane applications without encryption or high-speed packet forwarding | Select when dual eTSEC, SEC, or RapidIO are unnecessary-reduces BOM cost and thermal load |
| MPC8548CZQHBB | Same e500v2 core and QUICC Engine but older 90 nm process; lacks DDR2 support (DDR only); no PCIe (PCI only); lower max frequency (1.33 GHz vs 1.5 GHz) | Legacy upgrade path for existing MPC8548 designs requiring minimal PCB changes but no DDR2 or PCIe migration | Choose only for backward compatibility where DDR2 bandwidth or PCIe interconnect are not required |
Compared with MPC8567ECVTAQGG and MPC8548CZQHBB, the MPC8568ECVTAQGG uniquely combines dual eTSECs, DDR2, PCIe, RapidIO, and SEC in a single die-making it the only option for new carrier-edge designs demanding wire-speed encryption, 1 Gbps Ethernet aggregation, and scalable interconnect.

FAQ
What is the maximum DDR2 memory capacity supported by the MPC8568ECVTAQGG?
The MPC8568ECVTAQGG supports up to 16 GB of DDR2 SDRAM using its integrated memory controller. This is achieved via four chip select signals, 16 multiplexed address lines, and support for densities up to 4 Gbit per device. ECC functionality detects all single-bit errors and corrects them, while also detecting all double-bit errors within a memory word-ensuring data integrity in mission-critical networking applications where the MPC8568ECVTAQGG is deployed.
Does the MPC8568ECVTAQGG support both PCI Express and Serial RapidIO simultaneously?
Yes, the MPC8568ECVTAQGG supports simultaneous operation of x1/x2/x4 PCI Express and 1x/4x Serial RapidIO, subject to pin multiplexing constraints. Both interfaces share the same 2.5 Gbaud SerDes clock domain and cannot use spread-spectrum clocking due to RapidIO limitations. If x8 PCI Express is required, RapidIO must be disabled-this trade-off is documented in the MPC8568EEC Rev. 1 specification for the MPC8568ECVTAQGG.
How does the integrated Security Engine (SEC) in the MPC8568ECVTAQGG accelerate cryptographic operations?
The MPC8568ECVTAQGG's SEC performs single-pass cryptographic processing for protocols including SSL 3.0/TLS 1.0, IPSec, SRTP, and 802.11i. It integrates dedicated execution units-PKEU, DEU, AESU, AFEU, MDEU, KEU, and RNG-and supports four crypto-channels with multi-command descriptor chains. This enables wire-speed encryption (e.g., 450 Mbps SSL throughput) without burdening the e500v2 core, making the MPC8568ECVTAQGG ideal for secure media gateways and firewall appliances.
What Ethernet interface standards are supported by the eTSECs in the MPC8568ECVTAQGG?
The MPC8568ECVTAQGG features two enhanced three-speed Ethernet controllers (eTSEC1 and eTSEC2) supporting MII, RMII, GMII, RGMII, TBI, and RTBI physical interfaces. They are fully compliant with IEEE 802.3, 802.3u, 802.3z, 802.3ab, and 802.3ac standards, enabling 10/100/1000 Mbps operation. Each eTSEC includes 2 KB RX and 10 KB TX FIFOs, jumbo frame support up to 9.6 KB, and hardware VLAN tagging-key capabilities for the MPC8568ECVTAQGG's use in edge routers and industrial firewalls.
Is the MPC8568ECVTAQGG pin-compatible with earlier PowerQUICC III processors like the MPC8548?
No, the MPC8568ECVTAQGG is not pin-compatible with the MPC8548 or other PowerQUICC III predecessors. It uses a 783-pin PBGA package (CVTAQ) with distinct pin assignments optimized for DDR2, PCIe, RapidIO, and dual eTSEC interfaces-differing significantly from the MPC8548's 672-pin or 783-pin packages. Migration requires PCB redesign, though software drivers for eTSEC, QUICC Engine, and SEC are largely compatible across the family, easing firmware transition for the MPC8568ECVTAQGG.
