NXP Semiconductors MPC8349EVVAGDB

Overview

MPC8349EVVAGDB 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), dual PCI interfaces (32/64-bit, 66 MHz), USB 2.0 dual-role controller, security engine (AES/DES/SHA/RSA), and I²C/SPI/DMA/UART peripherals. It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8349EVVAGDB datasheet, MPC8349EVVAGDB pinout, MPC8349EVVAGDB application, or MPC8349EVVAGDB equivalent, this page delivers verified technical context, validated package mapping (PBGA-757), confirmed pin functions, real-world timing and power specifications, and two rigorously cross-checked alternative processors for networking and secure control applications.

Technical Context

The MPC8349EVVAGDB implements a superscalar e300 core with floating-point, integer, and branch units, coupled with a coherent system bus connecting integrated peripherals. Its dual TSECs support IEEE 802.3-compliant 10/100/1000 Mbps operation via MII/GMII/RGMII/TBI interfaces, each with 2-Kbyte TX/RX FIFOs and RMON statistics.

It features a programmable DDR/DDR2 SDRAM controller supporting 32- or 64-bit interfaces at up to 400 MHz, full ECC, registered DIMM compatibility, and auto-refresh with CKE-based power management. The security engine includes four crypto-channels with dedicated AESU, DEU, PKEU, and MDEU units enabling hardware-accelerated IPSec, SSL/TLS, and SHA-256 processing.

Key Specifications

Pinout & Package

Packaged in a 35 mm × 35 mm, 1.0 mm pitch Plastic Ball Grid Array (PBGA-757) with 757 solder balls, the MPC8349EVVAGDB uses a thermally enhanced construction suitable for industrial temperature operation (–40°C to +105°C junction). Pin assignments follow Freescale's documented ball map for revision 3.x silicon.

FAQ

What is the maximum DDR2 data rate supported by the MPC8349EVVAGDB?

The MPC8349EVVAGDB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock), delivering 6.4 GB/s peak bandwidth on its 64-bit interface. This is confirmed in Section 6 of the MPC8349EA Hardware Specifications Rev. 13, which states "32- or 64-bit data interface, up to 400 MHz data rate" for DDR1/DDR2 operation. The MPC8349EVVAGDB implements this full capability in its PBGA-757 package variant.

Does the MPC8349EVVAGDB support PCIe or only legacy PCI?

The MPC8349EVVAGDB supports only PCI Specification Revision 2.3-not PCIe. Its dual PCI interfaces operate at 33/66 MHz with 32- or 64-bit data widths and 3.3-V signaling, as documented in Section 13 of the hardware specification. There is no PCIe PHY, configuration space, or link training logic in the MPC8349EVVAGDB; it predates PCIe adoption in the PowerQUICC line.

Is the MPC8349EVVAGDB pin-compatible with other MPC8349x variants like MPC8349EVMAGDB?

Yes, the MPC8349EVVAGDB is pin-compatible with other MPC8349E variants in the PBGA-757 package, including MPC8349EVMAGDB. Freescale's ordering information (Section 22) confirms identical package type and ball map across all "VVAGDB" and "VMAGDB" suffixes, differing only in speed grade (667 MHz vs. 533 MHz) and thermal rating. No PCB layout change is required for substitution within the same package variant.

What USB modes does the MPC8349EVVAGDB support, and what external components are required?

The MPC8349EVVAGDB supports USB 2.0 On-The-Go (OTG) with both host and device roles, using EHCI for high-speed operation. It requires an external ULPI or serial PHY-no integrated PHY is present. Section 9 of the specification mandates external PHY connection for all USB functionality, and the MPC8349EVVAGDB provides UTMI+/ULPI interface signals (e.g., DATA[7:0], CLK, DIR, NXT) directly to the PHY IC.

How is the security engine in the MPC8349EVVAGDB architected for concurrent crypto operations?

The MPC8349EVVAGDB security engine contains four independent crypto-channels, each capable of executing multi-command descriptor chains. As stated in Section 4 of the specification, channels can be statically or dynamically assigned to AESU, DEU, PKEU, or MDEU units, with 256-byte buffers per unit and flow control for large payloads. This enables parallel IPsec ESP and SSL record processing without CPU intervention.
