Product details
Overview
MPC8349VVALFB 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 (TSEC), DDR1/DDR2 memory controller with ECC support, and integrated security engine for IPSec/SSL acceleration. It serves as a system-on-chip solution for network-attached storage, enterprise routing, and industrial gateway applications requiring deterministic real-time processing and hardware-accelerated cryptography.
For engineers reviewing the MPC8349VVALFB datasheet, MPC8349VVALFB pinout, MPC8349VVALFB application, or MPC8349VVALFB equivalent, this page delivers verified technical context including DDR2 timing compliance, TSEC GMII/RGMII interface support, PCI 2.3 host/agent mode operation, e300 core cache configuration, and security engine crypto-channel architecture - all specific to the MPC8349VVALFB TBGA-757 package and revision 3.x silicon.
Technical Context
The MPC8349VVALFB implements a superscalar e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches, lockable cache segments, and dynamic power management. Its coherent system bus interconnects dual TSECs, PCI controllers, DDR/DDR2 memory controller, and security engine - enabling simultaneous high-throughput packet forwarding, encrypted data path processing, and local bus peripheral control.
It supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock) with 64-bit interface, full ECC, registered DIMM compatibility, and SSTL18 I/O. The security engine integrates four independent crypto-channels with dedicated AESU (128/192/256-bit keys), DES/3DES, SHA-1/224/256, MD5, RNG, and PKEU supporting RSA up to 2048 bits - all accessible via descriptor-based DMA without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| e300 Core Frequency | Up to 667 MHz - enables Dhrystone 2.1 performance >1,400 DMIPS for real-time packet classification and routing. |
| DDR2 Interface | 64-bit, 400 MT/s - supports up to 4 GB addressable memory with ECC, critical for reliable NAS and firewall buffer management. |
| TSEC Ethernet | Dual 10/100/1000 Mbps controllers with RGMII/GMII/TBI - provides two independent gigabit PHY interfaces for WAN/LAN separation in edge routers. |
| PCI Interface | Dual 32-bit @ 66 MHz or single 64-bit @ 66 MHz, PCI 2.3 compliant - enables direct attachment of x86 co-processors, FPGA accelerators, or legacy I/O cards. |
| Security Engine | Four crypto-channels with AES-256, SHA-256, RSA-2048, and HMAC - offloads SSL/TLS handshake and IPsec ESP processing from main CPU. |
| Package | 757-pin TBGA (27 mm × 27 mm, 1.0 mm pitch) - requires controlled-impedance PCB stackup with dedicated VDD/AVDD/GVDD/LVDD/OVDD power planes. |
| Power Supply | VDD = 1.3 V ±60 mV (667 MHz), GVDD = 1.8 V ±90 mV (DDR2), OVDD = 3.3 V ±330 mV - mandates strict voltage tracking and sequencing per Figure 4. |
Pinout & Package
Package: 757-pin TBGA (27 mm × 27 mm, 1.0 mm pitch), RoHS-compliant, lead-free, thermal pad on underside for heatsink mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PORESET | Power-On Reset Input | Active-low synchronous reset requiring ≥32 CLKIN cycles; initiates boot sequence and configures CFG_RESET_SOURCE[0:2]. |
| HRESET | Host Reset Output | Open-drain output asserting system-wide reset; drives external peripherals and must be negated before SRESET. |
| CLKIN | Main System Clock Input | Accepts 33–66 MHz differential or single-ended clock; feeds PLL to generate CSB, DDR, USB, and TSEC clocks. |
| GVDD/GVSS | DDR2 I/O Power/Ground | Dedicated 1.8 V supply pair for DDR2 DQ/DQS/DM pins; requires low-noise regulation and tight decoupling near package corners. |
| TSEC0_TXD[0:3] | Gigabit Ethernet Transmit Data | RGMII-mode outputs driving PHY TXD lines; require 50-Ω series termination and length-matched routing to meet tskew ≤100 ps. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Security Acceleration | Four parallel crypto-channels process AES-256, SHA-256, and RSA-2048 concurrently - sustains >1 Gbps IPsec throughput without CPU load. |
| Memory Subsystem Flexibility | Single controller supports DDR1 (2.5 V SSTL2) and DDR2 (1.8 V SSTL18) with programmable timing - enables migration path from legacy to high-density memory. |
| Multi-Protocol Ethernet | Dual TSECs configurable as GMII, RGMII, MII, or TBI - allows direct connection to copper/fiber PHYs or switch fabric without glue logic. |
| PCI Host/Agent Dual Mode | PCI1 operates as host bridge; PCI2 as agent - permits MPC8349VVALFB to act as both system master and peripheral in modular chassis designs. |
| Boot Flexibility | Supports boot from I2C EPROM, local bus flash, or PCI device - simplifies field firmware updates and secure key provisioning. |

FAQ
What is the maximum DDR2 data rate supported by the MPC8349VVALFB?
The MPC8349VVALFB supports DDR2 SDRAM at up to 400 MT/s (200 MHz clock), with 64-bit interface width and full ECC capability. This is confirmed in Section 6 of the MPC8349EA Hardware Specifications Rev. 13, which applies to MPC8349VVALFB as a revision 3.x silicon part. The DDR2 controller uses SSTL18 I/O and supports registered DIMMs - enabling robust 4 GB memory configurations for network buffering in MPC8349VVALFB-based systems.
Does the MPC8349VVALFB include hardware cryptographic acceleration?
Yes, the MPC8349VVALFB integrates a dedicated security engine with four crypto-channels supporting AES-128/192/256, DES/3DES, SHA-1/224/256, MD5, HMAC, RSA-2048, and elliptic curve cryptography. As documented in Section 4 of the MPC8349EA Hardware Specifications, this engine operates independently of the e300 core and enables line-rate IPsec and SSL/TLS processing - a defining feature distinguishing MPC8349VVALFB from lower-tier PowerQUICC II Pro variants.
What package type and pin count does the MPC8349VVALFB use?
The MPC8349VVALFB uses a 757-pin TBGA package (27 mm × 27 mm, 1.0 mm pitch) with exposed thermal pad. This is explicitly stated in Section 18 "Package and Pin Listings" of the MPC8349EA Hardware Specifications Rev. 13, which covers all orderable MPC8349EA variants including MPC8349VVALFB. The pinout includes dedicated power domains (VDD, AVDD, GVDD, LVDD, OVDD), dual TSEC interfaces, DDR2 DQ/DQS groups, and PCI signal banks - requiring careful PCB layout per Freescale's design guidelines.
Can the MPC8349VVALFB operate in both PCI host and PCI agent modes simultaneously?
No - the MPC8349VVALFB supports PCI host mode on PCI1 and PCI agent mode on PCI2, but not simultaneous dual-role operation on the same interface. As specified in Section 13 of the MPC8349EA Hardware Specifications, PCI1 is configured as a host bridge with memory prefetching and posting capabilities, while PCI2 operates as an agent interface. This asymmetric configuration enables MPC8349VVALFB to serve as system controller while also connecting to PCI-based expansion cards - a key architectural feature of the MPC8349VVALFB design.
What boot sources are supported by the MPC8349VVALFB?
The MPC8349VVALFB supports boot from multiple sources: I2C-connected EPROM (via I2C-1), local bus flash memory (using GPCM protocol), or PCI device (in agent mode). Section 1 "Overview" and Section 22 "Ordering Information" of the MPC8349EA Hardware Specifications confirm this flexibility, allowing field-upgradable firmware and secure key loading. Boot source selection is controlled by CFG_RESET_SOURCE[0:2] pins at reset - a configurable feature implemented in all MPC8349VVALFB units.
