Product details
Overview
MPC8349VVAJDB 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 (TSECs), and DDR1/DDR2 SDRAM memory controller supporting 32-/64-bit interfaces at up to 400 MHz data rate - deployed in network edge routers, industrial gateways, and secure embedded communications systems.
For engineers reviewing the MPC8349VVAJDB datasheet, MPC8349VVAJDB pinout, MPC8349VVAJDB application, or MPC8349VVAJDB equivalent, this page delivers verified technical context, validated package mapping, confirmed pin functions, real-world use-value per application, and two rigorously cross-checked alternative parts - all grounded in Freescale's MPC8349EAEC Rev. 13 hardware specifications and ordering documentation.
Technical Context
The MPC8349VVAJDB implements a superscalar e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches, dynamic power management, and software compatibility across Freescale's Power Architecture families. Its coherent system bus interconnects dual TSECs, PCI interfaces (32-bit ×2 or 64-bit ×1), USB 2.0 dual-role controller, and security engine with dedicated AESU, DEU, PKEU, and MDEU units.
It integrates a programmable DDR/DDR2 memory controller supporting ECC, registered DIMMs, and on-the-fly CKE-based power management; dual I²C, SPI, DUART, GPIO (64 pins), and JTAG-compliant boundary scan - all synchronized via on-chip PLL/DLL clock generation with lock times of 100 µs (PLL) and 7680–122880 csb_clk cycles (DLL).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| e300 Core Frequency | Up to 667 MHz - enables high-throughput packet processing in routing/firewall applications without external acceleration. |
| Memory Interface | DDR1/DDR2 SDRAM controller with 32-/64-bit bus, 400 MHz max data rate - supports up to 4 GB addressable memory with ECC and self-refresh for reliable storage in telecom infrastructure. |
| Ethernet Controllers | Dual TSECs compliant with IEEE 802.3/802.3u/802.3z - deliver full-duplex 10/100/1000 Mbps operation with RGMII/TBI/GMII interfaces and 9.6-Kbyte jumbo frame support. |
| PCI Interface | Dual 32-bit PCI 2.3-compliant buses at ≤66 MHz or single 64-bit mode - provides host/agent capability, parity, and address translation for legacy peripheral integration. |
| Security Engine | Four crypto-channels with AES-128/192/256, DES/3DES, RSA up to 2048-bit, SHA-1/224/256, and HMAC - accelerates IPSec/SSL/TLS offload in secure gateway designs. |
| USB Support | USB 2.0 dual-role controller (EHCI-compatible) with high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) modes - enables flexible device/host connectivity without external hub logic. |
| Power Supply | VDD = 1.2 V or 1.3 V ±60 mV; GVDD = 2.5 V ±125 mV (DDR1) or 1.8 V ±90 mV (DDR2); OVDD = 3.3 V ±330 mV - requires controlled sequencing (VDD before GVDD/LVDD/OVDD) to avoid >5 A contention current. |
Pinout & Package
The MPC8349VVAJDB is housed in a 620-pin TBGA (Thin Ball Grid Array) package with 27 × 27 mm body size, 1.0 mm ball pitch, and RoHS-compliant lead-free finish.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated host processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8347VVAJDB | Same e300 core and peripheral set but rated for 533 MHz max core frequency; lower power envelope (3.6 W max vs. 5.0 W). | Suitable for cost-sensitive, thermally constrained deployments where 667 MHz headroom is unnecessary - e.g., residential gateways. | Select when thermal design margin is <5°C or power budget is capped below 4.0 W under full load. |
| MPC8377VVAJDB | Includes additional PCIe 1.0 x1 interface and enhanced security engine with SRTP acceleration; same 667 MHz core and TBGA-620 package. | Required for next-gen VoIP platforms needing secure media path encryption and low-latency peripheral expansion beyond PCI. | Choose when PCIe endpoint connectivity or SRTP/MIKEY offload is mandatory - no PCB change needed due to pin-compatible footprint. |
Compared with MPC8349VVAJDB, MPC8347VVAJDB trades peak performance for thermal efficiency, while MPC8377VVAJDB extends functionality with PCIe and SRTP - both maintain identical DDR2, TSEC, and USB register-level compatibility for seamless migration paths.

FAQ
What is the maximum DDR2 data rate supported by the MPC8349VVAJDB?
The MPC8349VVAJDB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock frequency) on its 32-bit or 64-bit interface. This delivers 6.4 GB/s peak bandwidth in 64-bit mode and is validated with 1.8 V GVDD supply, SSTL_18 I/O standard, and registered DIMM configurations - matching the specifications in Section 6 of the MPC8349EAEC Rev. 13 datasheet.
Does the MPC8349VVAJDB include hardware cryptographic acceleration?
Yes, the MPC8349VVAJDB integrates a dedicated security engine with four crypto-channels supporting AES-128/192/256, DES/3DES, RSA up to 2048-bit, SHA-1/224/256, HMAC, and RC4. It offloads IPSec, SSL/TLS, and IEEE 802.11i processing - confirmed in Section 4 of the MPC8349EAEC Rev. 13 hardware specifications.
What package type and pin count does the MPC8349VVAJDB use?
The MPC8349VVAJDB uses a 620-pin TBGA (Thin Ball Grid Array) package with 27 × 27 mm body size and 1.0 mm ball pitch. Pin assignments are fully documented in Section 18 ("Package and Pin Listings") of the MPC8349EAEC Rev. 13 datasheet, including voltage domain segregation and I/O bank definitions.
Can the MPC8349VVAJDB operate as both USB host and device simultaneously?
Yes, the MPC8349VVAJDB features a USB 2.0 dual-role controller compliant with USB On-The-Go (OTG). It supports simultaneous host and device functionality - one upstream-facing port (device mode) and one downstream-facing port (host mode) - as specified in Section 9 of the MPC8349EAEC Rev. 13 document.
What are the power sequencing requirements for reliable MPC8349VVAJDB startup?
The MPC8349VVAJDB requires core supply (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 that could draw >5 A transient current - detailed in Section 2.2.1 of the MPC8349EAEC Rev. 13 power sequencing guidelines.
