NXP Semiconductors MPC8347EVRADDB

Overview

MPC8347EVRADDB from NXP (formerly Freescale) 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/66-MHz interface, and hardware-accelerated security engine for IPSec/SSL/TLS. It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8347EVRADDB datasheet, MPC8347EVRADDB pinout, MPC8347EVRADDB application, or MPC8347EVRADDB equivalent, key selection criteria include its e300 core frequency headroom, dual TSEC timing compliance with IEEE 802.3z/802.3ac, DDR-1 ECC support, PCI host/agent mode flexibility, and integrated crypto-channel architecture with AES-256, SHA-256, and RSA-2048 acceleration.

Technical Context

The MPC8347EVRADDB implements a superscalar PowerPC e300 core with 32-KB instruction and 32-KB data L1 caches (lockable portions), dynamic power management, and software compatibility across Power Architecture families. Its DDR SDRAM controller supports programmable timing, four banks up to 1 Gbyte each, registered DIMM, and on-the-fly CKE-based self-refresh.

Two independent TSEC modules provide full-duplex GMII/RGMII/TBI/RTBI and MII interfaces compliant with IEEE 802.3–802.3z standards, each with 2-KB TX/RX FIFOs, 9.6-KB jumbo frame support, and RMON statistics. The security engine integrates four crypto-channels with dedicated execution units for AES, DES/3DES, SHA/MD5, ARC4, and RSA/DH/ECC, enabling concurrent IPSec/SSL offload.

Key Specifications

Pinout & Package

The MPC8347EVRADDB is packaged in a 676-pin TBGA (Thin Ball Grid Array) with 1.0-mm ball pitch, thermal pad exposed on underside, and RoHS-compliant finish. Pin assignments follow the MPC8347E Hardware Specifications Rev. 11 package diagram (Section 18).

Equivalent & Alternatives

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

Compared with MPC8349EVRADDB, the MPC8347EVRADDB offers lower power and cost at 667 MHz while retaining identical peripheral sets and security capabilities; versus MPC8548CVRAG, it provides proven TSEC-based Ethernet integration and simpler migration from legacy PowerQUICC II designs but lacks PCIe and higher-frequency e500 scalability.

FAQ

What is the maximum DDR data rate supported by the MPC8347EVRADDB?

The MPC8347EVRADDB supports DDR-1 SDRAM at up to 333 MHz data rate in the TBGA package (e.g., MPC8347EVRADDB), delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This is confirmed in Section 6 of the Hardware Specifications Rev. 11, which specifies 333 MHz operation for TBGA variants with 2.5-V SSTL2 I/O compatibility and full ECC support. The PBGA variant is limited to 266 MHz.

Does the MPC8347EVRADDB support PCIe?

No, the MPC8347EVRADDB does not support PCIe. It implements a PCI 2.2-compliant 32-bit/66-MHz interface only, as documented in Section 13 of the Hardware Specifications Rev. 11. PCIe support was introduced in later PowerQUICC III (MPC85xx) and QorIQ families. The MPC8347EVRADDB's PCI interface operates in host or agent mode with parity, delayed reads, and posted writes - but lacks PCIe-specific features like serial lanes, link training, or configuration space extensions.

What cryptographic algorithms are accelerated by the MPC8347EVRADDB security engine?

The MPC8347EVRADDB security engine accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), SHA-1/SHA-256, MD5, HMAC-SHA/MD5, ARC4 (40–128-bit keys), and RSA/DH/ECC (up to 2048-bit RSA, 511-bit ECC). These are implemented in dedicated execution units (AESU, DEU, MDEU, AFEU, PKEU) with four concurrent crypto-channels, as detailed in Sections 1.1 and 1.2 of the Hardware Specifications Rev. 11.

Is the MPC8347EVRADDB pin-compatible with the MPC8349EVRADDB?

Yes, the MPC8347EVRADDB and MPC8349EVRADDB share identical 676-pin TBGA mechanical packaging, pinout, and signal definitions, making them drop-in replacements. The MPC8349EVRADDB extends the e300 core frequency to 800 MHz while retaining identical TSEC, DDR, PCI, USB, and security engine functionality - confirmed in Freescale's MPC8349E documentation and ordering information tables (Section 23.1).

What is the recommended power supply sequencing for the MPC8347EVRADDB?

The MPC8347EVRADDB does not require strict voltage sequencing: VDD (1.2 V), GVDD (2.5 V), LVDD (2.5/3.3 V), and OVDD (3.3 V) may be applied in any order. However, Freescale recommends applying VDD before I/O supplies and asserting PORESET before supplies stabilize to minimize active drive time on I/O pins during ramp-up, as specified in Section 2.2 of the Hardware Specifications Rev. 11.
