NXP Semiconductors MPC8349VVAGDB

Overview

MPC8349VVAGDB from Freescale Semiconductor is a PowerQUICC II Pro integrated host processor featuring an embedded PowerPC 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 - deployed in network edge routers, industrial gateways, and secure communications appliances.

For engineers reviewing the MPC8349VVAGDB datasheet, MPC8349VVAGDB pinout, MPC8349VVAGDB application, or MPC8349VVAGDB 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 Freescale's MPC8349EAEC Rev. 13 hardware specification.

Technical Context

The MPC8349VVAGDB implements a superscalar e300 core with 32-Kbyte L1 instruction and data caches, dynamic power management, and software compatibility across Power Architecture families. Its coherent system bus interconnects dual TSECs, PCI controllers (32-bit/66 MHz or 64-bit/66 MHz), USB 2.0 host/device controller, and security engine with four crypto-channels supporting AES-256, SHA-256, RSA-2048, and DES/3DES.

It integrates DDR/DDR2 SDRAM controller with 32-/64-bit interface, up to 400 MHz data rate, four chip-select banks, and on-the-fly ECC correction. Clocking supports CLKIN or PCI_SYNC_IN primary input (≤66 MHz), with dedicated 125 MHz EC_GTX_CLK125 for TSEC gigabit operation and ±150 ps jitter tolerance.

FAQ

What is the maximum DDR2 data rate supported by the MPC8349VVAGDB?

The MPC8349VVAGDB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock) on its 64-bit interface. This is confirmed in Section 6 of the MPC8349EAEC Rev. 13 specification, which states "32- or 64-bit data interface, up to 400 MHz data rate" for DDR1/DDR2 operation. The MPC8349VVAGDB implements this capability with 1.8 V GVDD supply and SSTL2-compatible I/O.

Does the MPC8349VVAGDB support PCIe interfaces?

No, the MPC8349VVAGDB does not support PCIe. It features two PCI 2.3-compliant interfaces (32-bit/66 MHz or 64-bit/66 MHz), as documented in Section 13 of the MPC8349EAEC Rev. 13 specification. PCIe capability was introduced in later PowerQUICC families such as MPC8377, not in the MPC8349 series.

What are the required power supply sequencing requirements for the MPC8349VVAGDB?

The MPC8349VVAGDB requires core voltage (VDD/AVDD) to be applied before I/O supplies (GVDD/LVDD/OVDD), with VDD reaching 90% of nominal value before any I/O supply exceeds 0.7 V. This prevents I/O contention and excessive current draw (3–5 A), as specified in Section 2.2.1 of the MPC8349EAEC Rev. 13 document.

Can the MPC8349VVAGDB operate as a USB host and device simultaneously?

Yes, the MPC8349VVAGDB includes a USB 2.0 dual-role controller supporting On-The-Go (OTG) operation. It can function as either a host (with EHCI compliance and 480 Mbps high-speed support) or a device (with six programmable endpoints), as detailed in Section 9 of the MPC8349EAEC Rev. 13 specification.

Is the MPC8349VVAGDB pin-compatible with the MPC8347 series?

No, the MPC8349VVAGDB is not pin-compatible with the MPC8347 series. While both belong to the PowerQUICC II Pro family, they differ in package (MPC8347 uses PBGA-516 vs. MPC8349VVAGDB's TBGA-740), I/O count, and peripheral allocation - confirmed by comparing pin listings in Sections 18 of their respective hardware specifications.
