NXP Semiconductors MPC8349EVVAJFB

Overview

MPC8349EVVAJFB 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 three-speed (10/100/1000 Mbps) Ethernet controllers (TSEC), DDR1/DDR2 memory controller with ECC support, and integrated security engine for IPSec/SSL acceleration - deployed in network-attached storage, industrial gateways, and secure edge routers.

For engineers reviewing the MPC8349EVVAJFB datasheet, MPC8349EVVAJFB pinout, MPC8349EVVAJFB application, or MPC8349EVVAJFB equivalent, this page delivers verified electrical specs (1.3 V core, 2.5 V/1.8 V DDR I/O), thermal power data (up to 5 W at 667 MHz), PCI 2.3 compliance, and confirmed TSEC/GMII/RGMII interface timing - all validated against Rev. 13 hardware specifications.

Technical Context

The MPC8349EVVAJFB 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, PCI1/PCI2 controllers (32-bit/66 MHz or 64-bit/66 MHz), DDR/DDR2 memory controller (32-/64-bit, up to 400 MHz data rate), and security engine with four crypto-channels supporting AES-256, SHA-256, RSA-2048, and DES/3DES.

It integrates dual USB 2.0 controllers (one OTG-capable), DUART compatible with 16550D, I²C master/slave interfaces, SPI, 64 GPIO pins, and JTAG boundary scan per IEEE 1149.1. Clocking supports CLKIN or PCI_SYNC_IN primary sources with ±150 ps jitter tolerance and programmable PLL/DLL lock times (100 μs PLL, 7680–122880 csb_clk cycles DLL).

FAQ

What is the maximum DDR2 data rate supported by the MPC8349EVVAJFB?

The MPC8349EVVAJFB supports DDR2 SDRAM up to 400 MHz data rate (200 MHz clock) in 32-bit or 64-bit configurations. This is achieved with GVDD = 1.8 V ±90 mV and requires precise trace matching and termination per JEDEC DDR2-400 specifications. The controller supports registered DIMMs and full ECC, making MPC8349EVVAJFB suitable for mission-critical storage and routing applications demanding memory integrity.

Does the MPC8349EVVAJFB support PCIe interface?

No, the MPC8349EVVAJFB does not support PCIe. It implements two PCI 2.3-compliant interfaces - configurable as dual 32-bit or single 64-bit buses - but lacks PCIe physical layer, transaction layer, or configuration space. For PCIe capability, consider the pin-compatible MPC8377ERVAAJFB, which replaces PCI2 with PCIe x1 while retaining the same e300 core, dual TSEC, and security engine as MPC8349EVVAJFB.

What are the power sequencing requirements for MPC8349EVVAJFB?

MPC8349EVVAJFB requires core voltage (VDD/AVDD) to reach 90% of nominal value before any I/O supply (GVDD/LVDD/OVDD) rises above 0.7 V. Failure to observe this prevents I/O contention and avoids transient current spikes up to 5 A. PORESET must be asserted before power supplies stabilize. I/O rails GVDD, LVDD, and OVDD have no relative sequencing order among themselves, per Freescale Hardware Specifications Rev. 13.

Can MPC8349EVVAJFB operate with DDR1 and DDR2 memory simultaneously?

No, the MPC8349EVVAJFB memory controller supports either DDR1 (GVDD = 2.5 V) or DDR2 (GVDD = 1.8 V) in a given design - not both concurrently. The I/O voltage domain GVDD is shared across all DRAM pins, and the controller's timing registers are configured at boot for one standard. Mixed-mode operation is electrically and functionally unsupported; MPC8349EVVAJFB requires board-level selection of DDR1 or DDR2 during hardware design.

What USB modes does the MPC8349EVVAJFB support?

The MPC8349EVVAJFB integrates two USB 2.0 controllers: one supports On-The-Go (OTG) mode with both host and device functionality, and the other operates as a dedicated multi-port host controller. Both support high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operation, with external PHY connectivity via UTMI+, ULPI, or serial interfaces - enabling flexible firmware updates, peripheral attachment, and debug interfaces in final products.
