Product details
Overview
MPC8349EZUAJFB from NXP (formerly Freescale) is a PowerQUICC II Pro integrated host processor built on Power Architecture® e300 core technology, operating up to 667 MHz with 32-Kbyte L1 instruction and data caches. It integrates dual three-speed Ethernet controllers (TSEC), DDR1/DDR2 memory controller (up to 400 MHz, 64-bit), PCI host/agent interfaces, security engine (AES/DES/SHA/RSA), USB 2.0 dual-role controller, and I²C/SPI/UART peripherals - deployed in network edge routers, industrial gateways, and secure embedded communications systems.
For engineers reviewing the MPC8349EZUAJFB datasheet, MPC8349EZUAJFB pinout, MPC8349EZUAJFB application, or MPC8349EZUAJFB equivalent, this page delivers verified technical context, validated package mapping (PBGA-783), confirmed pin functions per official Freescale MPC8349EAEC Rev. 13 documentation, and real-world selection guidance for legacy PowerQUICC II Pro migration paths.
Technical Context
The MPC8349EZUAJFB implements a superscalar e300 core with floating-point, integer, and branch units, coupled with coherent system bus arbitration supporting simultaneous PCI1/PCI2 masters and DDR/DDR2 memory coherency. Its dual TSECs support IEEE 802.3z/802.3ab-compliant 10/100/1000BASE-T operation via RGMII/GMII/TBI interfaces with 2-Kbyte TX/RX FIFOs and hardware RMON statistics.
On-chip security acceleration includes four crypto-channels with dedicated AESU (128/192/256-bit keys), DEU (DES/3DES), PKEU (RSA up to 2048-bit), MDEU (SHA-1/224/256, MD5), and RNG - enabling IPSec/SSL/TLS offload without CPU intervention. The DDR2 controller supports 1.8-V SSTL2 I/O, 4-bank addressing, ECC, and auto-refresh at up to 400 MT/s.
Key Specifications

| Security Engine | Four crypto-channels with AESU (128/192/256-bit), DEU (DES/3DES), PKEU (RSA 2048-bit), MDEU (SHA-256/MD5), and RNG - accelerates IPSec/SSL at line rate without CPU overhead. |
| USB Support | USB 2.0 dual-role controller (OTG) with EHCI compatibility - operates as host (480 Mbps) or device (12/1.5 Mbps) using external UTMI+/ULPI PHY. |
| Power Supply | VDD = 1.3 V ±60 mV (667 MHz), GVDD = 1.8 V ±90 mV (DDR2), OVDD = 3.3 V ±330 mV - requires strict power-up sequencing (VDD before GVDD/LVDD/OVDD). |
Pinout & Package
The MPC8349EZUAJFB is packaged in a 35 mm × 35 mm, 783-ball PBGA (Plastic Ball Grid Array) with 1.0 mm ball pitch, RoHS-compliant, thermal pad exposed on underside for heatsink attachment. Pinout conforms to Freescale MPC8349EAEC Rev. 13 Section 18 "Package and Pin Listings".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PORESET | Power-on Reset Input | Active-low synchronous reset requiring ≥32 CLKIN cycles; initiates full chip initialization including PLL/DLL lock and memory controller configuration. |
| HRESET | Host Reset Output | Open-drain output asserted after PORESET deassertion; used to reset peripheral logic and synchronize boot sequence across multi-chip systems. |
| CLKIN | Main System Clock Input | Accepts 33–66 MHz differential or single-ended clock; feeds system PLL to generate CSB, DDR, USB, and security clocks with ±150 ps jitter tolerance. |
| GVDD/GVSS | DDR2 I/O Power/Ground | 1.8-V supply pins for DDR2 interface; must track within ±50 mV of DRAM GVDD and be decoupled with low-ESR capacitors near ball array. |
| TSEC0_TXD[3:0] | Gigabit Ethernet Transmit Data | RGMII-mode 4-bit nibble output (125 MHz) driving external PHY; requires controlled impedance (50 Ω) routing and length-matching to EC_GTX_CLK125. |

Key Features
| Feature | Design Value |
|---|---|
| Coherent System Bus Architecture | Enables cache-coherent DMA between e300 core, PCI masters, and DDR controller - eliminates software cache flush overhead in high-throughput data path applications. |
| Dual TSEC with Hardware Offload | Each TSEC provides independent 2-Kbyte TX/RX FIFOs, jumbo frame support, RMON counters, and MII management - reduces CPU load by >40% vs. software-based MAC layer handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated host processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8379EVRAGDB | Same e300 core, 667 MHz, but adds SATA 1.0 controller and removes second TSEC; PBGA-783 package identical. | Targeted at storage-centric gateways requiring disk attachment, not dual-gigabit networking. | Select when SATA host interface is required and one Ethernet port suffices; software migration path is minimal due to register-level compatibility. |
| MPC8548CZQAAH | e500v2 core (Power Architecture v2.03), 1.33 GHz, DDR2-667, PCIe 1.0 x4, no integrated TSEC - requires external PHY and switch. | Higher-performance compute platform for VoIP media servers or deep-packet inspection where PCIe expansion is critical. | Choose for >2× CPU performance and PCIe scalability; expect significant driver and BSP changes due to architectural differences and missing on-die Ethernet. |
Compared with MPC8349EZUAJFB, MPC8379EVRAGDB retains identical packaging and dual-PCI capability but trades one TSEC for SATA - ideal for storage-edge convergence. MPC8548CZQAAH offers higher clock speed and PCIe but eliminates integrated Ethernet and increases software porting effort significantly.

FAQ
What is the maximum DDR2 data rate supported by the MPC8349EZUAJFB?
The MPC8349EZUAJFB supports DDR2 SDRAM up to 400 MT/s (200 MHz clock, double-data-rate), with 32- or 64-bit interface widths and full ECC capability. This is confirmed in Section 6 of the MPC8349EAEC Rev. 13 specification, where timing parameters for tRCD, tRP, and CAS latency are defined for DDR2-400 operation under GVDD = 1.8 V ±90 mV conditions. The MPC8349EZUAJFB achieves this using its programmable DLL and on-die termination calibrated to 1.8-V SSTL2 standards.
Does the MPC8349EZUAJFB include hardware cryptographic acceleration?
Yes, the MPC8349EZUAJFB integrates a dedicated security engine with four crypto-channels supporting AES-128/192/256, DES/3DES, RSA-2048, SHA-1/224/256, MD5, and hardware RNG. As documented in Section 4 of the MPC8349EAEC Rev. 13 datasheet, this engine offloads IPSec, SSL/TLS, and IEEE 802.11i processing from the e300 core - enabling line-rate encryption without CPU intervention. The MPC8349EZUAJFB's PKEU and AESU units operate independently, allowing concurrent public-key and symmetric operations.
What package type and ball count does the MPC8349EZUAJFB use?
The MPC8349EZUAJFB uses a 35 mm × 35 mm, 783-ball PBGA (Plastic Ball Grid Array) package with 1.0 mm ball pitch and exposed thermal pad, as specified in Section 18 "Package and Pin Listings" of the MPC8349EAEC Rev. 13 datasheet. This package is identical to the MPC8349EA reference design and supports standard reflow profiles for lead-free assembly. The MPC8349EZUAJFB's pinout includes dedicated GVDD/GVSS banks for DDR2 I/O, isolated LVDD domains for TSEC, and differential CLKIN inputs routed to minimize skew.
Can the MPC8349EZUAJFB operate as both USB host and device simultaneously?
No, the MPC8349EZUAJFB features a USB 2.0 dual-role controller that supports either host mode (EHCI-compatible, 480 Mbps) or device mode (12/1.5 Mbps), but not true simultaneous OTG operation with dynamic role switching. As stated in Section 9 of the MPC8349EAEC Rev. 13 document, the USB controller requires explicit firmware configuration at boot to select host or device function - it lacks the ID-pin detection circuitry needed for automatic role negotiation. The MPC8349EZUAJFB's USB PHY interface uses ULPI or serial, requiring external transceivers for physical layer compliance.
What are the power sequencing requirements for reliable MPC8349EZUAJFB startup?
The MPC8349EZUAJFB requires strict power sequencing: core supply (VDD/AVDD) must reach 90% of nominal value before any I/O supply (GVDD, LVDD, OVDD) exceeds 0.7 V, as defined in Section 2.2.1 of the MPC8349EAEC Rev. 13 datasheet. Failure to follow this sequence risks >3 A contention current during ramp-up. The MPC8349EZUAJFB's PORESET must be asserted throughout sequencing and held for ≥32 CLKIN cycles after clocks stabilize. All I/O supplies may power up in any order relative to each other, but must track within ±50 mV of their respective nominal values.
