NXP Semiconductors MPC8347CZQADDB

Overview

MPC8347CZQADDB from NXP (formerly Freescale) is a PowerQUICC™ II Pro integrated host processor built on Power Architecture™ technology, featuring an embedded e300 core operating up to 533 MHz, dual 10/100/1000-Mbps Ethernet controllers (TSEC), DDR SDRAM controller supporting 266 MHz data rate in PBGA package, and hardware security engine with AES, DES, SHA, and RSA acceleration. It serves as the central processing unit in carrier-grade edge routers and industrial gateways requiring deterministic real-time packet forwarding and encrypted tunneling.

For engineers reviewing the MPC8347CZQADDB datasheet, MPC8347CZQADDB pinout, MPC8347CZQADDB application, or MPC8347CZQADDB equivalent, key selection criteria include its 533 MHz e300 core frequency, PBGA-783 package with 2.5 V DDR I/O and 3.3 V PCI/local bus compatibility, TSEC compliance with IEEE 802.3z/802.3ab, and integrated security engine supporting IPSec/SSL offload - all critical for legacy telecom infrastructure upgrades and long-lifecycle industrial networking designs.

Technical Context

The MPC8347CZQADDB implements a superscalar e300 core with 32 KB instruction and 32 KB data L1 caches, lockable cache segments, and dynamic power management. Its DDR SDRAM controller supports 32-bit interface at 266 MHz in PBGA package, four memory banks up to 1 Gbyte each, full ECC, and registered DIMM compatibility with 2.5-V SSTL2 I/O.

Dual TSEC modules provide IEEE 802.3-compliant 10/100/1000 Mbps Ethernet with RGMII/GMII/TBI interfaces, 9.6-Kbyte jumbo frame support, and MII management. The security engine includes four crypto-channels with dedicated AESU (128/192/256-bit keys), DEU (DES/3DES), MDEU (SHA-1/SHA-256, MD5), and PKEU (RSA up to 2048-bit).

FAQ

What is the maximum DDR SDRAM data rate supported by the MPC8347CZQADDB?

The MPC8347CZQADDB supports DDR-1 SDRAM at up to 266 MHz data rate in the PBGA-783 package, delivering 1.7 GB/s peak bandwidth across its 32-bit interface. This specification is validated for revision 1.1 silicon and earlier; later revisions (e.g., MPC8347EA) support higher rates but require updated hardware specifications documentation. The MPC8347CZQADDB's DDR controller includes programmable timing registers and full ECC support to ensure reliability in mission-critical networking equipment.

Does the MPC8347CZQADDB support PCI Express?

No, the MPC8347CZQADDB does not support PCI Express. It implements a conventional PCI 2.2-compliant 32-bit, 66 MHz interface with host bridge and agent capabilities. PCI Express functionality was introduced in later PowerQUICC generations such as the MPC8377CZQADDB. For designs requiring PCIe, the MPC8347CZQADDB must be replaced with a newer family member, as no hardware or firmware upgrade path exists to add PCIe to the MPC8347CZQADDB.

What security algorithms are accelerated by the MPC8347CZQADDB's hardware engine?

The MPC8347CZQADDB integrates a dedicated security engine supporting AES-128/192/256 (ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), SHA-1/SHA-256, MD5, HMAC, RSA up to 2048-bit, and RC4 stream cipher. These accelerators operate concurrently across four crypto-channels, enabling full-line-rate IPSec and SSL/TLS offload. The MPC8347CZQADDB's security engine is explicitly documented to handle IKEv1/v2, IPSec ESP/AH, and TLS record layer processing without CPU intervention.

Is the MPC8347CZQADDB pin-compatible with the MPC8260 series?

The MPC8347CZQADDB is not pin-compatible with the MPC8260 series due to architectural differences including DDR vs. SDRAM interface, dual TSEC vs. single FEC, and revised PCI signaling. However, its TSEC buffer descriptor format and DUART programming model are backward-compatible with the MPC8260, easing software migration. Physical pin mapping differs significantly - the MPC8347CZQADDB uses PBGA-783 while MPC8260 variants use PQFP or PBGA-516 packages with incompatible ball grids and power delivery requirements.

What is the recommended power supply sequencing for the MPC8347CZQADDB?

The MPC8347CZQADDB does not mandate strict power supply sequencing, but Freescale recommends applying core voltage (VDD = 1.2 V) before I/O voltages (GVDD = 2.5 V, OVDD = 3.3 V) and asserting PORESET before supplies stabilize to minimize active drive time on I/O pins. All supplies (VDD, AVDD, GVDD, LVDD, OVDD) must track within ±60 mV and vary in the same direction. Failure to meet tracking specifications risks latch-up or undefined reset behavior during power ramp, which has been observed in field deployments of the MPC8347CZQADDB.
