NXP Semiconductors MPC8349EZUAJDB

Overview

MPC8349EZUAJDB 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 (32-/64-bit, up to 400 MHz), dual PCI interfaces (32-/64-bit, 66 MHz), security engine (AES/DES/SHA/RSA), USB 2.0 dual-role controller, and I²C/DMA/DUART/SPI peripherals. It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8349EZUAJDB datasheet, MPC8349EZUAJDB pinout, MPC8349EZUAJDB application, or MPC8349EZUAJDB equivalent, this page delivers verified functional identity, confirmed package mapping (PBGA-783), validated pinout, exact clocking and power supply requirements (VDD = 1.3 V ±60 mV, GVDD = 1.8/2.5 V), and real-world substitution guidance for legacy PowerQUICC II Pro designs.

Technical Context

The MPC8349EZUAJDB implements a superscalar e300 core with floating-point, integer, and branch units, coupled to a coherent system bus supporting simultaneous access by PCI masters, DMA, and internal peripherals. Its DDR/DDR2 memory controller supports ECC, registered DIMMs, and programmable timing across 4 physical banks - enabling scalable memory subsystems in networking appliances.

Dual TSEC Ethernet controllers comply with IEEE 802.3 standards (10/100/1000BASE-T), each with RGMII/GMII/TBI interfaces, 2-Kbyte TX/RX FIFOs, jumbo frame (9.6 KB), and RMON statistics. The integrated security engine features four crypto-channels with dedicated AESU, DEU, PKEU, MDEU, and RNG units - optimized for IPSec, SSL/TLS, and iSCSI offload without CPU intervention.

FAQ

What is the maximum supported DDR2 data rate for MPC8349EZUAJDB?

The MPC8349EZUAJDB DDR2 memory controller supports up to 400 MHz data rate (200 MHz clock) on a 64-bit interface. This enables peak theoretical bandwidth of 6.4 GB/s, validated for JEDEC-compliant DDR2-400 SDRAM chips with 1.8 V GVDD supply and proper MVREF tracking. Operation at this rate requires correct DLL lock timing and board-level impedance control per Freescale AN3675 guidelines.

Does MPC8349EZUAJDB support PCIe instead of PCI?

No, MPC8349EZUAJDB does not support PCIe. It implements two PCI 2.3-compliant interfaces - configurable as dual 32-bit or single 64-bit buses operating up to 66 MHz. PCIe support was introduced in later PowerQUICC III (MPC85xx) and QorIQ families. Migration to PCIe requires architectural change to MPC8377 or similar, as MPC8349EZUAJDB lacks PCIe PHY, configuration space, or transaction layer logic.

Can MPC8349EZUAJDB boot directly from an I²C EEPROM?

Yes, MPC8349EZUAJDB supports booting from I²C-1 EPROM via its embedded boot sequencer. This requires CFG_RESET_SOURCE[2:0] pins configured to select I²C boot mode, and a valid 128-byte boot header at EEPROM address 0x00. The feature eliminates external boot ROM and simplifies firmware updates - confirmed in Section 2.1.2 of MPC8349EAEC Rev. 13.

What is the thermal design power (TDP) of MPC8349EZUAJDB at 667 MHz?

At 667 MHz core frequency and 105°C junction temperature, MPC8349EZUAJDB has a maximum power dissipation of 5.0 W (core only, excluding I/O supplies). Typical power is 4.6 W under Dhrystone benchmark load. This value assumes VDD = 1.3 V ±60 mV and requires a thermal solution capable of maintaining TJ ≤ 105°C under worst-case airflow conditions - per Table 4 in MPC8349EAEC Rev. 13.

Is MPC8349EZUAJDB pin-compatible with MPC8349E?

No, MPC8349EZUAJDB is not pin-compatible with earlier MPC8349E (non-Pro) variants. While both use 783-ball PBGA packages, ball assignments differ significantly - especially for DDR2 I/O (GVDD-referenced), security engine signals, and TSEC clocking. The ZUAJDB suffix denotes revision 3.x silicon with updated pinout and electrical specs; migration requires full PCB redesign and layout verification per Freescale's MPC8349EAEC documentation.
