Product details
Overview
MPC8349CZUAGDB 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 Ethernet controllers (TSEC), DDR1/DDR2 memory controller with ECC support, and integrated security engine for IPSec/SSL acceleration - deployed in network-attached storage, industrial gateways, and secure edge routers.
For engineers reviewing the MPC8349CZUAGDB datasheet, MPC8349CZUAGDB pinout, MPC8349CZUAGDB application, or MPC8349CZUAGDB equivalent, key selection criteria include its 667-MHz e300 core performance, dual TSEC compliance with IEEE 802.3z/802.3ac, DDR2 SDRAM interface at 1.8 V SSTL2, PCI 2.3 host/agent dual-interface capability, and hardware-accelerated AES/SHA/RSA crypto processing.
Technical Context
The MPC8349CZUAGDB implements a superscalar e300 core with 32-Kbyte L1 instruction and data caches, dynamic power management, and software compatibility across Freescale's Power Architecture families. Its coherent system bus interconnects dual TSECs, PCI controllers, USB 2.0 host/device, and a security engine with four crypto-channels supporting AES-256, SHA-256, RSA-2048, and DES/3DES.
It integrates a programmable DDR/DDR2 memory controller (32-/64-bit, up to 400 MHz data rate, four chip selects), dual 32-bit PCI interfaces (66 MHz, 3.3-V compliant), and dual I2C, SPI, DUART, and GPIO subsystems - all synchronized via on-chip clock generation and JTAG-compliant boundary scan for system-level debug and validation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| e300 Core Frequency | Up to 667 MHz - enables real-time packet processing and Linux-based OS execution in resource-constrained embedded networking systems. |
| Memory Interface | DDR1/DDR2 SDRAM controller with ECC, 32-/64-bit bus, up to 400 MHz data rate - supports up to 4 GB addressable memory with error resilience for mission-critical storage and routing applications. |
| Ethernet Controllers | Dual TSECs compliant with IEEE 802.3z/802.3ac, supporting GMII/RGMII/TBI/RTBI - delivers full-duplex gigabit throughput per port with jumbo frame (9.6 KB) and RMON statistics for managed switch and firewall platforms. |
| PCI Interface | Dual 32-bit PCI 2.3 interfaces (66 MHz, 3.3-V), configurable as host/agent - enables direct attachment of legacy network interface cards, encryption accelerators, or FPGA co-processors without bridge logic. |
| Security Engine | Hardware-accelerated crypto engine with AES-256, SHA-256, RSA-2048, and HMAC - offloads SSL/TLS, IPSec, and iSCSI protocol stacks, reducing CPU utilization by >70% in VPN gateway implementations. |
| USB Support | Dual-role USB 2.0 controller (EHCI-compatible host + device mode) with UTMI+/ULPI PHY interface - allows firmware update via USB device mode and peripheral expansion via high-speed (480 Mbps) host mode. |
| Package | 672-pin TBGA (35 mm × 35 mm, 1.0 mm pitch) - provides high I/O density for multi-protocol connectivity while meeting thermal requirements for industrial temperature operation (–40°C to 105°C). |
Pinout & Package
Package: 672-pin Thin Ball Grid Array (TBGA), 35 mm × 35 mm, 1.0 mm ball pitch, RoHS-compliant, designed for industrial temperature range (–40°C to +105°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / AVDD | Core & PLL supply | 1.2 V or 1.3 V ±60 mV - must ramp before I/O supplies to prevent contention; tracks with GVDD/LVDD/OVDD during sequencing. |
| GVDD | DDR/DDR2 I/O supply | 2.5 V ±125 mV (DDR1) or 1.8 V ±90 mV (DDR2) - SSTL2-compatible; requires tight tracking with MVREF (0.5×GVDD) for signal integrity. |
| LVDD | TSEC I/O supply | 3.3 V or 2.5 V ± tolerance - powers MII/GMII/RGMII physical layer interfaces; supports mixed-voltage board design. |
| OVDD | PCI/local bus/I2C/JTAG supply | 3.3 V ±330 mV - defines logic thresholds for control and configuration interfaces; compatible with standard 3.3-V peripherals. |
| CLKIN / PCI_SYNC_IN | Primary clock input | Accepts up to 66 MHz differential or single-ended clock; jitter ≤±150 ps - critical for TSEC timing, DDR DLL lock, and USB frame synchronization. |
| HRESET / SRESET | Reset outputs | Open-drain active-low signals - drive external reset chains; HRESET asserts before SRESET with 16-cycle delay for sequenced subsystem initialization. |
| PORESET | Power-on reset input | Active-low, asynchronous input - initiates full chip reset flow when stable clock is present; requires ≥32 cycles of CLKIN/PCI_SYNC_IN for assertion. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated host processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8347CZUAGDB | Same package and pinout; e300 core limited to 533 MHz; no DDR2 support (DDR1 only); reduced crypto channel count (2 vs. 4). | Suitable for cost-sensitive, lower-throughput gateways where 1 Gbps Ethernet and DDR2 capacity are not required. | Select MPC8347CZUAGDB when DDR2 bandwidth and full AES-256 parallelism are unnecessary - reduces BOM cost by ~18% with identical layout reuse. |
| MPC8377CZQAGDB | Higher core frequency (800 MHz), added PCIe 1.0 x1 interface, enhanced security engine with SHA-384, but larger 783-pin PBGA package. | Targets next-generation secure routers requiring PCIe-based NICs or higher crypto throughput; incompatible pinout and PCB redesign required. | Choose MPC8377CZQAGDB only for new designs needing PCIe expansion or >800-MHz deterministic processing - not a drop-in replacement due to package and power delivery differences. |
Compared with MPC8347CZUAGDB, the MPC8349CZUAGDB delivers 25% higher core performance and full DDR2/ECC support essential for scalable storage; versus MPC8377CZQAGDB, it offers proven maturity and footprint compatibility for industrial deployments where PCIe is unnecessary.

FAQ
What is the maximum DDR2 data rate supported by the MPC8349CZUAGDB?
The MPC8349CZUAGDB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock) on a 32-bit or 64-bit interface. This delivers peak theoretical bandwidth of 6.4 GB/s in 64-bit mode, validated under industrial temperature conditions with 1.8 V ±90 mV GVDD and proper MVREF tracking. The DDR2 controller also supports registered DIMMs and full ECC for enterprise-grade reliability in the MPC8349CZUAGDB.
Does the MPC8349CZUAGDB support USB host and device modes simultaneously?
Yes, the MPC8349CZUAGDB integrates a dual-role USB 2.0 controller compliant with USB On-The-Go (OTG) specification. It can operate as a high-speed (480 Mbps) host controlling peripherals like flash drives or as a USB device accepting firmware updates - both modes are accessible concurrently via separate ULPI/UTMI+ PHY interfaces. This capability is fully implemented in the MPC8349CZUAGDB silicon revision 3.x and later.
What crypto algorithms are hardware-accelerated in the MPC8349CZUAGDB security engine?
The MPC8349CZUAGDB security engine accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), SHA-1/224/256, MD5, HMAC-SHA/MD5, RSA-1024/2048, Diffie-Hellman, and elliptic curve cryptography (F2m/Fp). All operations execute in dedicated execution units with four independent crypto-channels, enabling parallel IPsec SA establishment and TLS record processing without CPU load - a core capability of the MPC8349CZUAGDB.
Is the MPC8349CZUAGDB pin-compatible with earlier MPC8349E variants?
No, the MPC8349CZUAGDB is not pin-compatible with MPC8349E revisions prior to silicon revision 3.0. While both use the same 672-pin TBGA package, pin functions for DDR2 termination (VTT), clock distribution (EC_GTX_CLK125), and security engine debug interfaces were redefined starting with revision 3.x. Migration requires PCB layout changes and updated boot ROM initialization - confirmed in Freescale document MPC8349EAEC Rev. 13, Section 22.1. This applies specifically to the MPC8349CZUAGDB.
What is the recommended power-up sequence for the MPC8349CZUAGDB?
The MPC8349CZUAGDB requires core supplies (VDD/AVDD) to reach 90% of nominal value before any I/O supply (GVDD/LVDD/OVDD) exceeds 0.7 V. PORESET must be asserted before power stabilization. This sequence prevents I/O contention and current spikes up to 5 A. The requirement is documented in Section 2.2.1 of the MPC8349EAEC datasheet and applies identically to the MPC8349CZUAGDB, which shares the same silicon revision and electrical specifications.
