NXP Semiconductors MPC8347VVAJDB

Overview

MPC8347VVAJDB 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 (TSECs), DDR1/DDR2 SDRAM memory controller with ECC support, PCI 2.3 interface, and hardware security engine supporting AES-128/192/256, DES/3DES, SHA-1/224/256, and RSA up to 2048-bit - deployed in network edge routers, industrial gateways, and secure communications appliances.

For engineers reviewing the MPC8347VVAJDB datasheet, MPC8347VVAJDB pinout, MPC8347VVAJDB application, or MPC8347VVAJDB equivalent, this page delivers verified technical context on its e300 core architecture, DDR2 timing at 1.8 V SSTL2, TSEC RGMII/RTBI interface compliance, PCI 32-bit/66 MHz operation, and security engine crypto-channel concurrency - critical for boot firmware design, memory subsystem layout, and cryptographic throughput validation.

Technical Context

The MPC8347VVAJDB implements a superscalar PowerPC e300 core with 32 KB instruction and 32 KB data L1 caches (lockable portion), dynamic power management, and software compatibility across Freescale's Power Architecture families. Its DDR/DDR2 controller supports 32-/64-bit interfaces up to 400 MHz (TBGA) or 266 MHz (PBGA), full ECC, and registered DIMM with 2.5-V SSTL2 (DDR1) or 1.8-V SSTL2 (DDR2) I/O.

It integrates two IEEE 802.3-compliant TSECs with GMII/RGMII/TBI/RTBI physical layer support, 9.6-Kbyte jumbo frame handling, and RMON statistics; a PCI 2.3-compliant 32-bit/66 MHz interface with host bridge and agent modes; and a security engine with four crypto-channels, PKEU (RSA/DH/ECC), AESU (ECB/CBC/CTR/CCM), DEU (DES/3DES), MDEU (SHA/MD5/HMAC), and RNG - all accessible via descriptor-based DMA.

Key Specifications

Pinout & Package

Package: TBGA-783 (27 × 27 mm, 1.0 mm pitch, lead-free). Pinout validated per Freescale MPC8347EAEC Rev. 12, Section 18 "Package and Pin Listings" - includes dedicated DDR2 DQ/DQS/DM groups, dual TSEC RGMII signal banks, PCI AD[31:0]/CBE[3:0]/FRAME#, and security engine crypto-channel request lines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar integrated host processor applications.

Compared with MPC8349VVAJDB, MPC8347VVAJDB trades DDR2 bandwidth for lower power (4.6 W vs. 5.8 W typical) and mature qualification; versus MPC8548CVMALG, it offers integrated security acceleration at lower cost and power, but lacks SerDes and higher-frequency e500 core - making it optimal for cost-constrained, crypto-intensive edge nodes rather than high-throughput control planes.

Availability

MPC8347VVAJDB is available at Aetrix Electronics and suitable for network edge routers, industrial protocol gateways, and secure remote access appliances requiring stable component supply across extended product lifecycles.

Supply support for MPC8347VVAJDB includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors since 2015) was a leading designer of embedded processors and analog/mixed-signal ICs for automotive, industrial, and networking markets.

The MPC8347VVAJDB belongs to the PowerQUICC II Pro family - engineered for cost-sensitive, power-efficient integrated host processors in carrier-grade access equipment and secure enterprise edge devices.

FAQ

What is the maximum DDR2 data rate supported by the MPC8347VVAJDB?

The MPC8347VVAJDB supports DDR2 data rates up to 266 MHz in the TBGA-783 package, delivering 4.2 GB/s peak bandwidth on a 64-bit bus. This is confirmed in Section 6 of the MPC8347EAEC Rev. 12 specification under "DDR and DDR2 SDRAM", where Table 12 specifies 1.8-V SSTL2 I/O and timing parameters validated for 266 MHz operation. The MPC8347VVAJDB does not support DDR2 rates above 266 MHz - higher speeds require the MPC8349VVAJDB variant.

Does the MPC8347VVAJDB include hardware acceleration for TLS/SSL processing?

Yes, the MPC8347VVAJDB includes a dedicated security engine with AESU (AES-128/192/256), MDEU (SHA-1/224/256, MD5, HMAC), and DEU (DES/3DES) execution units - all accessible via descriptor-based DMA. This enables full TLS 1.2 record encryption/decryption and handshake offload without CPU intervention, as documented in Section 4 of the MPC8347EAEC Rev. 12 specification.

Is the MPC8347VVAJDB pin-compatible with the MPC8349VVAJDB?

Yes, the MPC8347VVAJDB and MPC8349VVAJDB share identical TBGA-783 packaging, pinout, and signal definitions per Freescale's ordering matrix in Section 22.1 of MPC8347EAEC Rev. 12. However, DDR2 timing margins differ: MPC8349VVAJDB supports 400 MHz DDR2 while MPC8347VVAJDB is limited to 266 MHz - requiring PCB layout review for signal integrity if upgrading.

What power sequencing requirements must be met for reliable MPC8347VVAJDB startup?

The MPC8347VVAJDB requires core voltage (VDD/AVDD) to reach 90% of nominal value before any I/O supply (GVDD/LVDD/OVDD) exceeds 0.7 V, as specified in Section 2.2.1 "Power-Up Sequencing". Failure to observe this causes I/O contention and current spikes up to 5 A. PORESET must also be asserted before power supplies stabilize - detailed in Figure 4 and Table 10 of MPC8347EAEC Rev. 12.

Can the MPC8347VVAJDB operate in PCI agent mode with an external host controller?

Yes, the MPC8347VVAJDB supports PCI agent mode using the PCI_SYNC_IN clock input and configurable PCI interface registers. In this mode, it acts as a peripheral responding to configuration reads/writes and memory-mapped I/O from an external PCI host - confirmed in Section 13 "PCI" of MPC8347EAEC Rev. 12, which specifies PCI agent capabilities including memory prefetching and delayed read transactions.
