Product details
Overview
MPC8349ECVVAJDB from NXP (formerly Freescale) 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 TSEC Ethernet controllers, and DDR1/DDR2 memory controller supporting up to 400 MHz data rate - deployed in network-attached storage, industrial gateways, and secure edge routers.
For engineers reviewing the MPC8349ECVVAJDB datasheet, MPC8349ECVVAJDB pinout, MPC8349ECVVAJDB application, or MPC8349ECVVAJDB equivalent, key selection criteria include e300 core frequency headroom, dual-TSEC IEEE 802.3 compliance, DDR2 1.8-V I/O compatibility, security engine crypto-channel concurrency, and PCI 2.3 host/agent mode flexibility.
Technical Context
The MPC8349ECVVAJDB implements a superscalar e300 core with 32-Kbyte L1 instruction and data caches, lockable cache segments, and dynamic power management. Its coherent system bus interconnects dual TSECs, PCI controllers (PCI1 agent + PCI2 host), DDR/DDR2 memory controller, and security engine with four crypto-channels.
It integrates hardware-accelerated cryptographic functions including AES-128/192/256, DES/3DES, SHA-1/224/256, MD5, RSA up to 2048-bit, and ECC - all accessible via descriptor-based DMA channels independent of CPU execution. Clocking supports multiple PLL-derived domains: CSB at 333 MHz, DDR at 400 MHz, and TSEC GTX at 125 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| e300 Core Frequency | Up to 667 MHz - enables real-time packet processing and Linux kernel scheduling for multi-service edge nodes. |
| DDR/DDR2 Interface | 32-/64-bit, up to 400 MHz data rate - supports 1 Gbyte per bank across 4 banks with full ECC and self-refresh. |
| TSEC Ethernet | Dual 10/100/1000-Mbps controllers compliant with IEEE 802.3z/ac/u - each with 2-Kbyte TX/RX FIFOs and RMON statistics. |
| Security Engine | Four crypto-channels with AESU, DEU, PKEU, MDEU, RNG - handles concurrent IPSec/SSL/TLS offload without CPU intervention. |
| PCI Interface | Dual 32-bit or single 64-bit PCI 2.3-compliant interface - supports host bridge and agent modes with address translation and parity. |
| Power Supply | VDD = 1.3 V ± 60 mV (667 MHz); GVDD = 1.8 V ± 90 mV (DDR2) or 2.5 V ± 125 mV (DDR1) - requires strict voltage tracking. |
| Thermal Dissipation | Max 5 W at 667 MHz core / 333 MHz CSB - mandates heatsink design per JEDEC JESD51-2 for TBGA package. |
Pinout & Package
Package: 620-pin TBGA (35 mm × 35 mm, 1.27 mm pitch), RoHS-compliant, thermal pad exposed on underside for heatsink attachment.
| 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 asserted after PORESET negation; drives downstream peripherals and triggers SRESET after 16 cycles. |
| CLKIN | Main System Clock Input | Accepts 33–66 MHz differential or single-ended clock; feeds system PLL to derive CSB, DDR, USB, and TSEC clocks. |
| GVDD/GVSS | DDR2 I/O Power/Ground | 1.8-V supply pair for DDR2 DQ/DQS/DM pins; must track within ±50 mV of DRAM GVDD and maintain MVREF = 0.5×GVDD. |
| TSEC0_TXD[0:3] | Gigabit Ethernet Transmit Data | RGMII-mode outputs driving PHY; require 50-Ω series termination and controlled impedance routing to meet 125-MHz timing. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Cache Locking | Enables deterministic real-time interrupt latency by preventing critical code/data eviction from 32-Kbyte L1 instruction/data caches. |
| On-the-Fly DDR2 Power Management | CKE gating and self-refresh entry/exit controlled autonomously during low-traffic periods - reduces idle memory power by >40%. |
| PCI Address Translation Units | Two independent ATUs map host-to-peripheral address spaces, enabling legacy PCI devices to coexist with modern memory-mapped peripherals. |
| USB OTG Dual-Role Controller | Single EHCI-compliant controller supporting simultaneous device enumeration and host operation - eliminates need for external USB switch logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated host processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8347ECVVAJDB | Same e300 core and peripheral set but capped at 533 MHz core / 266 MHz CSB; no DDR2 support - only DDR1 at 2.5 V. | Suitable for cost-sensitive gateways where 1-Gbps Ethernet and AES-256 are not required. | Select when thermal budget is constrained (<3.6 W max) and DDR2 density (>1 Gbyte) is unnecessary. |
| MPC8377ECVVAJDB | Adds dual USB 2.0 host controllers and enhanced security engine with SHA-384/512; same 667 MHz core and DDR2 support. | Targeted at high-assurance applications requiring FIPS 140-2 Level 3 validation and dual USB peripheral hosting. | Choose when USB peripheral expansion (e.g., 4G/LTE modems, biometric readers) and extended crypto coverage are mandatory. |
Compared with MPC8347ECVVAJDB, MPC8349ECVVAJDB delivers 25% higher core throughput and DDR2 support for denser memory configurations; versus MPC8377ECVVAJDB, it trades USB host count and SHA-384/512 for lower unit cost and identical DDR2/TSEC performance - making it optimal for balanced throughput-security-cost edge nodes.

FAQ
What is the maximum DDR2 data rate supported by the MPC8349ECVVAJDB?
The MPC8349ECVVAJDB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock) across a 32- or 64-bit interface. This enables peak theoretical bandwidth of 6.4 GB/s in 64-bit mode, sufficient for high-throughput packet buffering and video preprocessing tasks. The DDR2 I/O operates at 1.8 V with SSTL2-compatible signaling and requires precise MVREF = 0.5 × GVDD tracking per JEDEC specification. MPC8349ECVVAJDB achieves this via on-die DLL and programmable timing registers.
Does the MPC8349ECVVAJDB support PCIe or only legacy PCI?
The MPC8349ECVVAJDB implements PCI Specification Revision 2.3 - not PCIe. It provides two configurable PCI interfaces: PCI1 supports agent mode (target-only), while PCI2 supports host bridge functionality. Both operate at 33 or 66 MHz with 32-bit or combined 64-bit data paths. There is no native PCIe PHY, transaction layer, or configuration space mapping in MPC8349ECVVAJDB; PCIe capability requires external bridge ICs. MPC8349ECVVAJDB's PCI design prioritizes compatibility with legacy industrial peripherals over serial lane scalability.
How many crypto algorithms does the security engine in MPC8349ECVVAJDB accelerate?
The MPC8349ECVVAJDB security engine accelerates 12 distinct cryptographic primitives across five execution units: AES-128/192/256 (AESU), DES/3DES (DEU), RSA/DH/ECC up to 2048-bit (PKEU), SHA-1/224/256 and MD5 (MDEU), and RC4 (AFEU). Each of its four crypto-channels can execute independent descriptor chains, enabling concurrent IPSec ESP, SSL record encryption, and SSH key exchange without CPU involvement. MPC8349ECVVAJDB's crypto throughput exceeds 200 Mbps for AES-CBC and 40 Mbps for RSA-2048 signing.
What boot sources are natively supported by the MPC8349ECVVAJDB?
The MPC8349ECVVAJDB supports boot from NOR flash (via local bus chip select 0), NAND flash (with hardware BCH ECC), SPI serial flash (via dedicated SPI controller), and I2C EEPROM (using I2C-1 interface during early boot). Boot configuration is selected via CFG_BOOT[0:2] pins and optionally overridden by I2C-loaded parameters. The boot sequencer validates image integrity using CRC-32 before loading to DDR2, and supports secure boot via HMAC-SHA256 signature verification when the security engine is enabled. MPC8349ECVVAJDB does not support direct boot from USB or PCIe devices.
Is the MPC8349ECVVAJDB pin-compatible with other PowerQUICC II Pro processors?
No, the MPC8349ECVVAJDB is not pin-compatible with other PowerQUICC II Pro variants such as MPC8347 or MPC8377. While all share the 620-pin TBGA footprint, signal assignments differ significantly - particularly for DDR2 vs DDR1 I/O voltage domains (GVDD), TSEC pin multiplexing (RGMII vs GMII), and security engine interface signals. Migration requires PCB redesign due to incompatible pin functions and voltage rail routing. MPC8349ECVVAJDB's unique pinout is documented in Section 18 "Package and Pin Listings" of its hardware specifications.
