Product details
Overview
MPC8349CVVAJDB from Freescale Semiconductor is a PowerQUICC II Pro integrated host processor built on Power Architecture® technology, featuring an e300 core operating up to 667 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSECs), DDR1/DDR2 memory controller with ECC support, and integrated security engine for IPSec/SSL acceleration. It serves as the central processing and networking hub in carrier-grade edge routers and industrial gateways requiring deterministic real-time packet handling and hardware-accelerated crypto.
For engineers reviewing the MPC8349CVVAJDB datasheet, MPC8349CVVAJDB pinout, MPC8349CVVAJDB application, or MPC8349CVVAJDB equivalent, this page delivers verified technical context on its e300 core timing, TSEC GMII/RGMII interface compatibility, DDR2-400 memory controller constraints, PCI 2.3 host/agent dual-mode operation, and security engine crypto-channel allocation - all critical for board-level bring-up and long-lifecycle embedded deployment.
Technical Context
The MPC8349CVVAJDB implements a superscalar e300 core with 32-Kbyte L1 instruction and data caches, dynamic power management, and software compatibility across Freescale's Power Architecture families. Its coherent system bus interconnects dual TSECs, PCI controllers, DDR/DDR2 memory controller, and security engine with four independent crypto-channels.
It supports simultaneous DDR1 (2.5-V SSTL2) and DDR2 (1.8-V SSTL2) interfaces at up to 400 MHz data rate across 32- or 64-bit buses, with full ECC, up to 4 physical banks, and registered DIMM support. The security engine integrates dedicated execution units for RSA (up to 2048-bit), AES (128/192/256-bit), SHA-256, MD5, and RC4, each accessible via programmable descriptor chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| e300 Core Frequency | Up to 667 MHz - enables Dhrystone 2.1 DMIPS/MHz performance for real-time packet forwarding and control-plane processing. |
| DDR/DDR2 Controller | 32-/64-bit interface, up to 400 MHz data rate - supports 1 Gbyte per bank with ECC, essential for reliable buffer memory in telecom infrastructure. |
| TSEC Interfaces | Dual 10/100/1000 Mbps Ethernet with GMII/RGMII/TBI/RTBI - provides IEEE 802.3-compliant line-rate switching without external PHY arbitration logic. |
| PCI Interface | Dual 32-bit or single 64-bit, up to 66 MHz, PCI 2.3 compliant - enables direct attachment of legacy network accelerators or FPGA co-processors with host/agent flexibility. |
| Security Engine | Four crypto-channels with PKEU, AESU, DEU, MDEU, RNG - offloads IPSec ESP/AH, TLS handshake, and iSCSI digest generation from main CPU. |
| Power Supply | VDD = 1.3 V ±60 mV (667 MHz), GVDD = 2.5 V ±125 mV (DDR1) or 1.8 V ±90 mV (DDR2) - requires tight tracking between core and I/O rails to prevent contention during power-up. |
| Thermal Dissipation | Max 5.0 W at 667 MHz, TJ = 105°C - mandates heatsink design with ≥1.8°C/W junction-to-ambient thermal resistance for sustained operation. |
Pinout & Package
Package: 672-pin TBGA (35 mm × 35 mm, 1.0 mm pitch), RoHS-compliant, lead-free, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | Primary clock input | Accepts 1–66 MHz differential or single-ended reference; determines CSB frequency via PLL ratio; must be stable before PORESET negation. |
| PORESET | Power-on reset input | Active-low asynchronous reset; requires ≥32 CLKIN cycles assertion when in PCI host mode; initiates boot sequence from configured chip select. |
| HRESET | Host reset output | Open-drain signal driven after internal reset flow completes; used to synchronize peripheral resets; asserts for ≥512 PCI_SYNC_IN cycles. |
| EC_GTX_CLK125 | Gigabit Ethernet reference clock | 125 MHz LVDS-compatible clock for TSEC transmitter; duty cycle 47–53%; jitter ≤±150 ps RMS - critical for RGMII/RTBI timing margin. |
| GVDD/GVSS | DDR/DDR2 I/O supply | Separate 2.5 V (DDR1) or 1.8 V (DDR2) rail; must track within ±50 mV of DRAM VDD; MVREF derived at 0.5×GVDD with ±2% noise tolerance. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Security Engine | Four independent crypto-channels with dedicated PKEU, AESU, DEU, and MDEU - enables concurrent IPSec tunnel setup, SSL record encryption, and SHA-256 hashing without CPU intervention. |
| Dual TSEC Controllers | Each with 2-Kbyte TX/RX FIFO, jumbo frame (9.6 KB), RMON statistics, and MII management - eliminates need for external switch fabric in dual-homed firewall appliances. |
| Flexible Memory Interface | Programmable DDR1/DDR2 timing, 32-/64-bit data bus, up to 4 banks, and read-modify-write support - allows migration between memory generations without PCB redesign. |
| PCI Dual-Mode Operation | PCI1 supports host bridge + agent mode; PCI2 supports host-only - enables use as both system controller and peripheral expansion root in modular chassis designs. |
| Boot Flexibility | Configurable boot source via CFG_RESET_SOURCE pins: local bus ROM, I2C EPROM, or serial flash - simplifies field firmware recovery and secure boot key loading. |
Applications
| Carrier-Grade Edge Router | Industrial Protocol Gateway |

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated host processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8349EVRAGDB | Same e300 core, identical pinout, but rated for 533 MHz max (vs. 667 MHz); lower thermal envelope (3.6 W max). | Suitable for cost-sensitive, lower-throughput edge nodes where 100 Mbps crypto offload suffices. | Select when thermal budget is constrained and full 667 MHz performance is unnecessary; verify DDR2 timing margins at reduced frequency. |
| MPC8377EVRAGDB | Enhanced variant with additional USB 2.0 host port, larger L2 cache (256 KB), and higher PCI bandwidth (dual 64-bit); not pin-compatible. | Required for multi-protocol gateways needing three independent USB hosts (e.g., cellular modem + GPS + storage). | Choose only if new PCB layout is feasible; offers 30% higher Dhrystone score but increases BOM cost and power by ~1.2 W. |
Compared with MPC8349CVVAJDB, MPC8349EVRAGDB trades peak frequency for thermal headroom while retaining full functional equivalence, whereas MPC8377EVRAGDB extends capability at the cost of mechanical and electrical redesign - making MPC8349CVVAJDB optimal for high-throughput, thermally demanding carrier-edge deployments where pin compatibility and proven reliability are mandatory.

FAQ
What is the maximum DDR2 data rate supported by the MPC8349CVVAJDB?
The MPC8349CVVAJDB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock) on a 32- or 64-bit bus. This is achieved with GVDD = 1.8 V ±90 mV and requires DLL lock times ranging from 7680 to 122,880 csb_clk cycles depending on the system PLL ratio. The controller enforces strict setup/hold timing validated for JEDEC-compliant DDR2-400 components.
Does the MPC8349CVVAJDB support PCIe or only legacy PCI?
The MPC8349CVVAJDB supports only PCI Specification Revision 2.3 - not PCIe. It features two configurable PCI interfaces: PCI1 operates in host or agent mode, and PCI2 operates in host-only mode. Both support 32-bit or 64-bit data widths at up to 66 MHz, with parity, address translation, and coherency enforcement - but lack PCIe's serial topology, link training, or advanced power states.
How many crypto algorithms can the MPC8349CVVAJDB execute concurrently?
The MPC8349CVVAJDB security engine supports true concurrency across four crypto-channels, each capable of independent command descriptor chains. This allows simultaneous execution of RSA key exchange (PKEU), AES-GCM encryption (AESU), SHA-256 hashing (MDEU), and RC4 stream cipher (AFEU) - confirmed in the hardware specifications for revision 3.x silicon and later, which includes MPC8349CVVAJDB.
What boot sources are supported by the MPC8349CVVAJDB?
The MPC8349CVVAJDB supports boot from local bus ROM (8/16/32-bit configurable), I2C-1 EPROM, or serial flash via SPI, selected by CFG_RESET_SOURCE[0:2] pins at reset. Boot sequencer hardware loads initial instructions directly from these sources without CPU intervention, enabling secure, field-upgradable firmware with minimal external components.
Is the MPC8349CVVAJDB pin-compatible with earlier MPC8347 variants?
No, the MPC8349CVVAJDB is not pin-compatible with MPC8347 series devices. While both belong to the PowerQUICC II Pro family and share architectural similarities, MPC8349CVVAJDB uses a 672-pin TBGA package with distinct pin assignments for DDR2 I/O, TSEC clocks, and security engine interfaces - confirmed in Section 18 "Package and Pin Listings" of the MPC8349EA Hardware Specifications Rev. 13.
