NXP Semiconductors MPC8349EVVAJDB

Overview

MPC8349EVVAJDB 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 10/100/1000-Mbps TSEC Ethernet controllers, DDR1/DDR2 memory controller (32-/64-bit, up to 400 MHz), and integrated security engine supporting AES, DES, SHA, RSA, and RNG. It serves as a system-on-chip for network-attached storage, industrial gateways, and secure edge routers.

For engineers reviewing the MPC8349EVVAJDB datasheet, MPC8349EVVAJDB pinout, MPC8349EVVAJDB application, or MPC8349EVVAJDB equivalent, this page delivers verified electrical specs (VDD = 1.3 V ±60 mV, GVDD = 1.8 V/2.5 V, OVDD = 3.3 V), thermal power data (5 W max at 667 MHz), DDR2 timing lock requirements (7680–122880 csb_clk cycles), and confirmed alternative part options aligned with Freescale's documented ordering matrix.

Technical Context

The MPC8349EVVAJDB 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 interfaces (32/64-bit, 66 MHz), USB 2.0 dual-role controller, and security engine with four crypto-channels.

It supports DDR/DDR2 SDRAM with full ECC, registered DIMM, and programmable timing; dual PCI buses with host/agent mode flexibility; and IEEE 802.3-compliant Ethernet with RGMII/TBI/GMII physical layer support. The security engine integrates dedicated execution units for AES (128/192/256-bit), DES/3DES, SHA-1/224/256, MD5, and true random number generation.

FAQ

What is the maximum DDR2 data rate supported by the MPC8349EVVAJDB?

The MPC8349EVVAJDB supports DDR2 SDRAM up to 400 MHz data rate (200 MHz clock) on its 32- or 64-bit interface. This is confirmed in Section 6 of the hardware specifications, where AC timing parameters and DLL lock times are defined for 200 MHz operation under GVDD = 1.8 V. Higher rates are not validated or guaranteed for MPC8349EVVAJDB.

Does the MPC8349EVVAJDB include hardware support for AES encryption?

Yes, the MPC8349EVVAJDB includes a dedicated Advanced Encryption Standard Unit (AESU) within its security engine, supporting AES-128, AES-192, and AES-256 in ECB, CBC, CCM, and counter modes. This is explicitly documented in Section 1, Overview, and Section 4.4 of the reference manual, enabling full-line-rate IPSec and SSL acceleration.

What are the power sequencing requirements for the MPC8349EVVAJDB?

The MPC8349EVVAJDB requires VDD (core) to reach 90% of nominal before any I/O supply (GVDD, LVDD, OVDD) exceeds 0.7 V, per Figure 4 and Section 2.2.1. Failure to follow this prevents I/O contention and avoids transient current spikes up to 5 A. PORESET must be asserted before supplies stabilize.

Is the MPC8349EVVAJDB pin-compatible with the MPC8379EVVAJDB?

No, the MPC8349EVVAJDB is not pin-compatible with the MPC8379EVVAJDB. Although both are 620-pin TBGA packages, the MPC8379EVVAJDB reassigns pins for additional USB PHY signals, thermal monitoring, and enhanced DDR2 timing controls - confirmed in Freescale's MPC8379EC document revision history and ordering matrix.

What Ethernet physical layer interfaces does the MPC8349EVVAJDB support?

The MPC8349EVVAJDB supports RGMII, GMII, TBI, and RTBI for 1000-Mbps operation, plus MII for 10/100-Mbps, as specified in Section 8. Each TSEC includes configurable I/O voltage (LVDD = 2.5 V or 3.3 V) and internal FIFOs, enabling direct connection to common PHYs without level-shifting.
