Product details
Overview
MPC8347VRADD 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), DDR SDRAM controller supporting 32-/64-bit interfaces at up to 333 MHz (TBGA), PCI 2.2-compliant 32-bit interface at 66 MHz, and hardware-accelerated security engine for IPSec/SSL/TLS with AES-128/192/256, DES/3DES, SHA-1/256, and RSA.
For engineers reviewing the MPC8347VRADD datasheet, MPC8347VRADD pinout, MPC8347VRADD application, or MPC8347VRADD equivalent, this page delivers verified technical context on its e300 core architecture, DDR timing constraints, TSEC RGMII/GMII interface support, PCI host/agent mode operation, and security engine crypto-channel configuration - all critical for networking gateway, industrial router, and secure edge appliance design.
Technical Context
The MPC8347VRADD implements a superscalar PowerPC e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches, lockable cache segments, and dynamic power management. It integrates a DDR SDRAM controller with full ECC, page-mode support, and programmable timing for DDR-1 devices up to 1 Gbit x8/x16.
Its dual TSECs comply with IEEE 802.3z/802.3ab/802.3ac, support GMII/RGMII/TBI/RTBI physical interfaces, and include 2-Kbyte TX/RX FIFOs per channel plus RMON statistics. The security engine contains four independent crypto-channels with dedicated AESU, DEU, MDEU, PKEU, and AFEU units.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated host processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8349EVRADD | Same e300 core, higher max frequency (800 MHz), added SATA controller, no USB OTG support | Better suited for storage-integrated gateways; lacks USB device mode needed for peripheral attachment | Select MPC8349EVRADD only if SATA interface and >667 MHz performance are required and USB device functionality is unnecessary |
| MPC8377VRADD | Includes integrated SerDes supporting SGMII/XAUI, adds second PCI interface, same security engine | Targeted for multi-port 10G-capable switches; higher pin count and thermal envelope than MPC8347VRADD | Choose MPC8377VRADD when 10-Gigabit Ethernet backplane connectivity or dual PCI domains are mandatory |
Compared with MPC8347VRADD, MPC8349EVRADD trades USB flexibility for higher compute headroom and SATA, while MPC8377VRADD adds SerDes and dual PCI at the cost of increased complexity and board area - making MPC8347VRADD the optimal balance for cost-sensitive, dual-gigabit, crypto-accelerated edge routing.

FAQ
What is the maximum DDR data rate supported by the MPC8347VRADD?
The MPC8347VRADD supports DDR-1 SDRAM at up to 333 MHz in the TBGA package variant, delivering 2.7 GB/s peak bandwidth on the 64-bit interface. This is confirmed in Section 6 of the MPC8347E Hardware Specifications (Rev. 11, Feb 2009), which specifies 333-MHz operation for TBGA and 266-MHz for PBGA. The MPC8347VRADD uses the TBGA package, so its maximum DDR data rate is 333 MHz.
Does the MPC8347VRADD support USB On-The-Go functionality?
Yes, the MPC8347VRADD includes a dual-role USB 2.0 controller compliant with USB On-The-Go (OTG) specifications. As documented in Section 4 of the MPC8347E Hardware Specifications, it supports both device and host modes simultaneously - including upstream-facing port operation as a device and downstream-facing root hub operation as a host - with EHCI compatibility and high-speed (480 Mbps) capability.
What are the power supply sequencing requirements for the MPC8347VRADD?
The MPC8347VRADD does not require strict voltage ramp ordering, but Freescale recommends applying core voltage (VDD = 1.2 V) before I/O voltages (GVDD = 2.5 V, OVDD/LVDD = 3.3 V) and asserting PORESET prior to full power stabilization. This minimizes unintended I/O driving during power-up, as specified in Section 2.2 "Power Sequencing" of the MPC8347E Hardware Specifications (Rev. 11).
How many crypto algorithms does the MPC8347VRADD security engine accelerate?
The MPC8347VRADD security engine accelerates five major algorithm families: AES (128/192/256-bit keys in ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), SHA-1/SHA-256 and MD5 hash functions, RSA and ECC public-key operations (up to 2048-bit RSA, 511-bit ECC), and RC4 stream cipher. These are implemented across dedicated execution units (AESU, DEU, MDEU, PKEU, AFEU) within its four crypto-channels.
Is the MPC8347VRADD pin-compatible with other PowerQUICC II Pro processors like the MPC8349E?
No, the MPC8347VRADD is not pin-compatible with the MPC8349E. Although both use 672-pin TBGA packages, their pinouts differ significantly - particularly in DDR signal allocation, PCI bus routing, and security engine interface signals - as confirmed by comparing Tables 18–1 and 18–2 in the MPC8347E and MPC8349E Hardware Specifications. PCB layout reuse is not feasible without redesign.
